V-Series (Vertical) Slip Clutches

The V-Series Slipper is a mechanical slip clutch that provides torque control for capping and driving applications where a thrust load is applied.

  • May be used for pulley applications
  • Design allows rebuilding, if necessary
  • Can accommodate shaft sizes up to 1 inch
  • Integrated ball bearing allows thrust loads of 150 to 650 pounds without any effect on torque
  • Torque capacities of up to 200 lb-in

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.

Written as: VAS20-4-4

1. Type of Clutch

V = V-Series Slipper

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)

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