Torque Settings & Capacity

  • Fixed torque settings are denoted ‘F’ and adjustable torque settings are denoted ‘A’ in the configured part number
  • The torque capacities provided in the specification tables are based on continuous operation at 50 RPM and are only a guideline
    • Torque, RPM, duty cycle and life are interdependent – a reduction of any of these will allow an increase in any other variable
    • For example: running at 25 RPM will allow twice the torque, or running for only 10% of the cycle will allow higher RPM, etc.)
    • The limit is based on heat build-up measured in watts per:
      Watts = Torque (inch pounds) x RPM x Duty Cycle* x 0.011.
      *(% of the time the clutch is slipping, expressed as a decimal. For example, 0.5 = 50% of the time the clutch is slipping)
    • Please contact us to discuss high torque, high RPM, and rapid cycling applications

Note: Torque control in one direction can be achieved by combining with our overrunning (one-way) clutch.

Part Number Configuration

Example:

(1) (2) (3) ( 4) – (5) – (6) – (T=*)
(P) (F) (S) (16) – (4) – (4) – (T=2)

Written as: PFS16-4-4 T=2

*Indicate torque value for fixed/preset torque, e.g. T=2

1. Type of Clutch

S = Multi-plate Slipper
P = Single-plate Slipper
Y = Cartridge only

2. Torque Setting

A = Adjustable torque
F = Factory preset (fixed) torque. Indicate torque value as T= ___

3. Installation Type

S = Shaft to shaft
O = Shaft-through for mounting to pulley, gear, sprocket, etc.

4. Outer Diameter

Generally represented in sixteenths of an inch

5. Cartridge Bore Size

Represented in sixteenths of an inch (4/16″ = 1/4″). For metric, add MM after bore size (e.g. SAS24-4MM)

6. Housing Bore Size

Represented in sixteenths of an inch (6/16″ = 3/8″). For metric, add MM after bore size (e.g. SAS24-4MM-6MM)

*Torque (T=)

Indicate torque value if requesting fixed/preset torque, T = ___

Bore diameters (dimension ‘B’) other than the standard sizes shown are available up to the maximum diameter shown, sized in inches or millimeters
