The adjustable friction clutches are rotary friction devices with adjustable drag or slip torque. Controlled slip takes place between the hub and housing whenever the load exceeds the set torque.

Where to use:
Light power drives, pumps and small generators.

• Three sizes – up to 3Nm torque capacity
• 4 interface styles
• Set screw or clamp connection
• Compact proportions
• Use a torque limiter, tensioning, or overrun device

Couplings: Bore Reducers
Bore adaptors offer a convenient way of adapting a coupling to a variety of shaft diameters, typically at the R & D stage. A range of motor options, for example, can be accommodated with one coupling and a selection of bore reducers.

When fitted to set screw hubs, adaptors prevent the screws from scoring the shafts and permit repeated re-positioning and easy removal of the coupling.

The adaptors feature a feathered head, which sits in the chamfer at the bore entry and prevents over-insertion.
