Polyclutch®

Slip-Ease Slip Clutches

The Slip-Ease is a compact mechanical slip clutch with an axial loaded multi-plate design. For applications where space is at a premium and low backlash is required.

  • Torque capacities of up to Nm 454 kg. (1000 lb-in.)
  • Can accommodate shaft sizes up to 31,8 mm (1,25″) (see dimension B – Max. in Specifications)
  • For a smaller option for miniature applications, see Size 12 (footprint of only 19,05 mm (1,25″) diameter)
  • Available in a fixed torque or adjustable torque configuration
  • Miniature size 12 version has extremely small footprint of only 19,05 mm (3/4″) diameter

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

1. Type of Clutch

E = Slip-Ease Clutch

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″= 6,35 mm). For metric, add MM after bore size (e.g. EFO44-12MM)

6. Housing Bore Size

Represented in sixteenths of an inch (6/16″ = 3/8″ = 9,53 mm). For metric, add MM after bore size (e.g. EAO44-10MM-10MM)

Example

(1) (2) (3) ( 4) – (5) – (6)
(E) (A) (S) (32) – (12.7MM) – (12.7MM)

Written as: EAS32-12.7MM-12.7MM

Slip-Ease clutches start with the letter ‘E’

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