- 4 interface styles
- Set screw or clamp connection
- Compact proportions
- Use a torque limiter, tensioning, or overrun device
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.
