Redefining total coupling value
FALK STEELFLEX The simplest, most cost-effective coupling ®
Falk originated the tapered grid design as well as shot peening to increase fatique strength and torque ratings. Falk Steelflex redefines total coupling value up to 7.5 million in-lb, 932 000 Nm torque. Steelflex offers simpler initial installation than gear couplings. The unique “replace in place” design eliminates the need to move hubs or re-align shafts, reducing element change-out time. When you look at the overall savings in initial costs, spare parts costs, and labor costs for installation, alignment and replacement - plus improved ratings and a 5 Year Heavy-Duty Warranty - it’s easy to see what Falk’s Steelflex Grid Couplings have over the competition. No other coupling in the torque range can touch Steelflex for cost-effective performance and reliability.
Features that give Steelflex the lowest lifetime operating cost Longer Life Tapered grids, made of high strength alloy steel, are quenched and tempered to spring hardness. The grid surface is then precision shot peened to compress the surface molecules. The effect is a dramatic increase in rating, providing reserve strength for longer life or allowing a smaller size coupling to be selected. This precision technology was originally used in the production of sophisticated aircraft components.
Extended Maintenance Periods Now you can install Steelflex and lubricate it with Falk Long Term Grease (LTG) and forget periodic, routine maintenance for five years. Falk LTG grease was developed specifically for couplings. It resists the separation of the oil and thickening agent that occurs in typical greases. The initial use of Falk LTG coupling grease will eliminate routine lubrication cycles while still providing the necessary lubrication to the tapered grid. With LTG, Steellflex combines the high torque performance of a gear coupling and the low maintenance of a disc or elastomer coupling.
Quick, Easy Installation… Replace-In-Place Design The grid is the wearing member of a Steelflex coupling and it is a fraction of the complete coupling cost. Tapered grids are accessible through the quickly removable cover. The replace-in-place design of the replacement grids allows them to be dropped in without the need to remove or reposition hubs or realign shafts as required with gear couplings and many elastomer designs. When coupling-connected equipment must be moved, the job takes longer and costs a lot more.

How to Select
Standard Selection Method (except T41/T44 &T63)
Type T63 Static (holding) Brake Applications
The standard selection method can be used for most motor, turbine, or engine driven applications. The following information is required to select a flexible coupling: l Horsepower or torque. l Running rpm. l Application or type of equipment to be connected (motor to pump, gear drive to conveyor, etc.). l Shaft diameters l Shaft gaps l Physical space limitations. l Special bore or finish information and type of fit.
1. SIZE: The brake rating must equal or exceed the application requirements. Determine the required coupling size by comparing the application loads (from Steps A and B below) to the coupling brake rating listed on Page 28. Use the highest torque value calculated to determine the coupling size.
Exceptions are High Peak Loads and Brake Applications. For these conditions use the Formula Selection Method in the next column, or consult your local Falk Representative for assistance.
B. For repetitive high peak load applications, use the system peak torque in lb-ft. (Repetitive is defined as more than 1000 times during the expected coupling life.)
1. RATING: Determine system torque. If torque is not given, calculate as shown below: HP x 63,000 System Torque (lb - in) = rpm Where horsepower is the actual or transmitted power required by the application (if unknown, use the motor or turbine nameplate rating) and rpm is the actual speed the coupling is rotating. Applications that require rapid changes in direction or torque reversals should be referred to Falk Engineering. 2. SERVICE FACTOR: Determine appropriate service factor from Table 2, Page 10. 3. REQUIRED MINIMUM COUPLING RATING: Determine the required minimum coupling rating as shown below: Minimum Coupling Rating = S.F. (Service Factor) x Torque (lb-in) 4. TYPE: Refer to Page 6 and select the appropriate coupling type. 5. SIZE: Turn to appropriate pages for the coupling type chosen and trace down the torque column to a value that is equal or greater than that determined in Step 3 above. The coupling size is shown in the first column. 6. CHECK: Check speed (rpm), bore, gap, and dimensions. STANDARD SELECTION EXAMPLE: Select a coupling to connect a 75 hp, 1750 rpm electric motor driving a lobe type blower. Motor shaft diameter is 2.375”, blower shaft diameter is 1.750”. Shaft extensions are 5.375” and 4.500”. Selection is replacing a gear type coupling with a .125” gap. 1. DETERMINE REQUIRED RATING: 75 HP x 63,000 System Torque (lb - in) = = 2700 1750 rpm 2. SERVICE FACTOR: From Table 2 = 1.25 3. REQUIRED MINIMUM COUPLING RATING: 1.25 X 2700 lb-in = 3375 lb-in
A. For normal service applications, use the application torque in ft-lb. System Torque (lb - ft) =
Transmitted HP x 5250 rpm
2. CALIPER TORQUE BRAKE RATING: For the coupling size selected, compare the caliper brake torque rating on Page 29 to the holding torque requirement of the application. Falk recommends that the caliper torque rating (min.) be at least two times the holding torque requirement for static applications to compensate for the possibility of foreign matter on the disc surfaces, loss of condition of the brake pad surfaces, or other conditions that may affect the holding ability of the caliper brake. Caliper brakes and brake discs listed are designed primarily for static and/or emergency brake applications. NOTE: Check brake system and lining wear after emergency stops. They can, however, also be used for dynamic stopping if only used occasionally, such as shutting down the equipment for the day or between shift changes. For stopping high inertia systems or for applications that require more frequent stopping, consult your local Falk Representative. 3. CHECK: Check maximum bores, speeds, and dimensions.
Type T63 Stopping or Service Brake Applications 1. SIZE: The coupling brake rating must equal or exceed the application requirements. Determine the required coupling size by comparing the application loads (from Steps A, B and C below) to the coupling brake rating listed on Page 28. Use the highest torque value calculated to determine the coupling size. A. For the selected caliper brake and disc diameter, use the maximum brake torque in lb-ft. B. For normal service applications, use the application torque in lb-ft. System Torque (lb - ft) =
Transmitted HP x 5250 rpm
C. For repetitive high peak load applications, use the system peak torque in lb-ft. (Repetitive is defined as more than 1000 times during the expected coupling life.) 2. CHECK: Check maximum bores, speeds, and dimensions.
4. SIZE: From Page 12 a Size 1070T is the proper selection based on a torque rating of 8000 lb-in exceeding the required minimum coupling rating of 3,375 lb-in. 5. CHECK: Allowable speed capacity of 4125 (T10) exceeds the required speed of 1750 rpm. Maximum bore capacity of 2.500” exceeds the actual shaft diameters.

How to Select
Formula Selection Method (except T41/T44 & T63)
FORMULA SELECTION EXAMPLE — High Peak Load:
The Standard Selection Method can be used for most coupling selections. The procedures below should be used for: l High Peak Loads. l Brake Applications (where the brake disc or brake wheel is to be an integral part of the coupling, consult the Factory for design options).
Select a coupling for reversing service to connect a gear drive low speed shaft to a runout mill table roll. The electric motor rating is 50 hp at the base speed and the system peak torque at the coupling is estimated to be 150,000 lb-in. Coupling speed is 77 rpm at the motor base speed. The drive shaft diameter is 4.000 with a keyway of 1.000” x .500” The runout table roll diameter is 5.250 with a keyway of 1.250” x .625”. Maximum shaft gap is 7.00” long.
Providing system peak torque and frequency, duty cycle, and brake torque rating will allow for a more refined selection using the Formula Selection Method. 1. HIGH PEAK LOADS: Use one of the following formulas for applications using motors with torque characteristics that are higher than normal; applications with intermittent operations, shock loading, inertia effects due to starting and stopping and or system induced repetitive high peak torques. System Peak Torque is the maximum torque that can exist in the system. Select a coupling with a torque rating equal to or greater than selection torque calculated below. A. NON-REVERSING HIGH PEAK TORQUE Selection Torque (lb-in) = System Peak Torque or Selection Torque (lb - in) =
System Peak HP x 63,000 rpm
B. REVERSING HIGH PEAK TORQUE Selection Torque (lb-in) = 2 x System Peak Torque or 2 x Peak HP x 63,000 Selection Torque (lb - in) = rpm C. OCCASIONAL PEAK TORQUES (Non-Reversing) If a system peak torque occurs less than 1000 times during the expected coupling life, use the following formula: Selection Torque (lb-in) = .5 x System Peak Torque or Selection Torque (lb - in) =
.5 x Peak HP x 63,000 rpm
For reversing service select per step B. 2. BRAKE APPLICATIONS: If the torque rating of the brake exceeds the motor torque use the brake rating as follows: Selection Torque (lb-in) = Brake Torque Rating x S.F.
1. TYPE: Refer to Page 6 and select the appropriate coupling type. 2. REQUIRED MINIMUM COUPLING RATING: Use the Reversing High Peak Torque formula in Step 1B. 2 x 150,000 = 300,000 = Selection Torque 3. SIZE: From Page 17, Size 1150T35 with a torque rating of 320,000 exceeds the selection torque of 300,000 lb-in. 4. CHECK: The 1150T35 has a maximum BE dimension of 7.38”; the shaft hub has a maximum bore of 10.000” with one rectangular key, (Table 14, Page 34 ); the T hub bore has a maximum bore of 8.000”) with one rectangular key (Table 13, Page 34); and the allowable speed of 1500 rpm and the dimensions on Page 17 meet the requirements.

t For engine drives, refer to Table 3. Electric motors, generators, engines,
compressors and other machines fitted with sleeves or straight roller bearings usually require limited end float couplings. If in doubt, provide axial clearances and centering forces to Falk for a recommendation. Q For balanced opposed design, refer to Falk. s If people are occasionally transported, refer to Falk for the selection of the proper size coupling. ¨ For high peak load applications (such as Metal Rolling Mills) refer to the Falk.
TABLE 3 — Engine Drive Service Factors ª Service Factors for engine drives are those required for applications where good flywheel regulation prevents torque fluctuations greater than ±20%. For drives where torque fluctuations are greater or where the operation is near a serious critical or torsional vibration, a mass elastic study is necessary. No. of Cylinders

An automatic proximity cutout switch in the motor starter control circuit of controlled torque coupling or clutch application is recommended for protection of connected equipment and coupling or clutch where damaging thermal buildup could develop. Refer to Slip Torque Performance Charts on Pages 22 through 25 to determine if an automatic proximity sensor cutout switch is required.
When the underspeed cutout switch is wired for automatic reset, the drive is immediately ready for service (after overload is removed) without resetting the circuit at any point. To restart the drive, just press either the main or remote control start button. The motor will not maintain normal operation if the overload has not been removed because the motor contractor circuit will reopen as soon as the start button is released.
The proximity cutout switch speed control is adjustable at the control box. It is set at a required cutout speed and continually compares the actual speed of the driven shaft with the set cutout speed. The control box can be mounted in an approximate space of 3 inches wide by 3 inches deep by 5 inches high.
The customer may incorporate a warning light or an alarm to the circuit to signal the operator of an overload or shutdown condition. Refer to Service Manual 428-440 for complete details.
During overload, the coupling or clutch slips at a predetermined speed. When the driven shaft speed drops below the cutout switch speed setting, it opens the motor circuit and the drag load stops the motor shaft.
Overhanging Hubs When the distance between shaft ends is greater than the Coupling gap or when the coupling or clutch hub length is greater than the usable shaft length, overhang one or both hubs. For Type T41, if this results in less than one shaft diameter of hub engagement, check key stresses or use a semi-standard long T hub listed in Table 21, Page 39 or submit application details to the Falk CAUTION: The effect of open keyways on coupling or clutch balance should always be considered.

Slip Torque Performance Charts — Sizes 2LT, 1020-1050 T41/T44 The following charts are for LT, T41, T41-2, T44 and T44-2 couplings or clutches. The coupling or clutch slip torque setting and operating speed determine the length of time a coupling or clutch can slip without exceeding its thermal capacity. An automatic cutout switch (see Page 21) is REQUIRED on applications as indicated in the upper right of the charts (Footnote 1) and is recommended on applications where “minutes of slip and non-slip” are exceeded. CAUTION: Thermal conditions in the slip torque performance charts apply only when the controlled torque hub is mounted on the driving shaft. When the controlled torque hub is mounted on the driven shaft reduce the slip time by 50%. During slip, heat is generated at the friction lining surfaces. The following charts specify the thermal capacities. When the torque (slip torque at the slip speed — not motor horsepower) being dissipated during a slip period exceeds the thermal capacity of the coupling or clutch, the following conditions will result:
10 8 6 5 4 336
2. Excessive sleeve bearing wear. 3. Warping of controlled torque hub flange and drive plate flange. 4. Heavy smoke and possibly fire. 5. Complete coupling or clutch failure. The limits specified in these charts must be adhered to for proper operation of controlled torque couplings or clutches in overload systems. Refer to Falk all applications requiring operation beyond the coupling or clutch thermal capacity.

Floating Shaft/Selections Introduction — Floating shaft diameters have been preselected to transmit the coupling torque and need only to be checked for allowable speed.
D. Determine the allowable shaft length for the required operating speed. For Speeds under 540 rpm — Read the maximum allowable shaft length to the left of the required shaft diameter.
Construction — Standard shafts are solid, AISI 1018 or 1020 cold rolled steel. Also available is an optional solid, AISI 1018, fully turned, hot rolled steel shaft.
For Speeds over 540 rpm — Trace right from the shaft diameter determined along the diagonal line to the point of intersection with the required vertical operating speed line. Trace right along the horizontal line to the right and read the maximum allowable shaft length.
Determine the Allowable Shaft Length A. Select the coupling size per Pages 7 and 26. B. From Page 26, determine shaft diameter (Dimension SD) for the coupling selected. C. From the table below, locate the floating shaft diameter (Dimension SD) determined in Step B.
F. If a longer shaft is required, reduce the operating speed if practical, or select the next larger size coupling. Note: For such conditions, the use of a tubular shaft design should be considered, refer application details to the local Falk Representative.

Type T90
Engine Flywheel Adapter/Dimensions — Inches
Used primarily to connect the flywheel of an engine to the driven machinery. Adapter plates are designed to accommodate standard SAE J620 bolt patterns. The T90 design provides for higher torque ratings with resulting smaller sizes and lower costs than elastomer coupling designs. The flexible gridmember provides torsional damping in addition to accepting misalignment. Adapter plates are bolted and doweled to the hub to provide a secure joint. Selection — Determine the proper Steelflex coupling size using the selection method. Check size selected against those shown in table below for the clutch size used on the engine flywheel. If the coupling size is not shown, refer all details to Falk.

OVERHANGING HUBS — Hubs may be overhung on the shafting provided there is more than one shaft diameter of hub/shaft engagement for clearance fits, or more than 0.75 times shaft diameter hub/shaft engagement for interference fits. If hub engagement is less than what is required, use a standard long hub listed in Table 21 on Page 39, or submit application details to the Factory. Dimension L must be equal to or greater than Dimension SD for clearance fits, or greater than Dimension SD times .75 for interference fits. For Type T63, Dimension Y must be equal to or greater than Dimension X. Example: SD = 4”; then L must be 4” or more for clearance fits or 3” or more for interference fits.

TABLE 19 — Misalignment Capacity – Inches Q
Coupling Misalignment
RECOMMENDED INSTALLATION MAXIMUM
Maximum life and minimum maintenance for the coupling and connected machinery will result if couplings are accurately aligned. Coupling life expectancy between initial alignment and maximum operating limits is a function of load, speed and lubrication. For applications requiring greater misalignment, refer application details to the Factory. Angular misalignment is expressed in degrees and as the difference between the value of X minus Y, as illustrated. Parallel misalignment is the distance P between shaft center lines as shown.
