HRC Coupling

This is the most frequently used flexible shaft coupling or “spider coupling”, consisting of two metal hubs or bosses and a rubber element or spider. The hubs can be supplied in pilot bored or taper bush versions, with a choice of which way the bush is fitted i.e. from the front or back.

Tyre Coupling

This is a very popular choice of coupling which offers great versatility to designers, particularly when an amount of shaft misalignment is an issue. This is a taper bush type coupling with a choice bush fitting.

L-Flex Coupling

This is a widely used jaw coupling, comprising of two cast iron hubs and a rubber element or spider. These are very compact couplings so are not available with taper bushes; these are normally supplied with nominal pilot bore, allowing the customer to have it bored and keyed to their specifications. AR Bearings also offer a machining service.

Chain Couplings

These are made up by using two simplex (single row) sprockets bound together by wrapping duplex (double row) chain all the way around teeth and joined with a connecting link. These are compact and very powerful couplings as the torque is apportioned over the entire strand of chain and all the teeth of the sprockets. They are also fairly simple and quick to install.
