Aluminium jaw coupling hubs

Aluminium jaw coupling hubs are lightweight pilot bore hubs designed for smaller coupling sizes. They work in small pumps, fans, gearboxes and automation drives.

Aluminium jaw coupling hubs - low inertia with frequent starts

Low mass means a low moment of inertia, which is why the hubs perform well in drives with frequent starts, braking and changes of direction of rotation - the motor reaches speed faster and the bearings are less loaded. You bore the hole out precisely for your shaft.

Type A and B aluminium hubs for smaller jaw couplings

Type A and B aluminium hubs for smaller jaw coupling sizes. The size is given in the product name. In larger and heavily loaded drives, hubs from the Cast iron or Steel groups are a better choice.

Questions and answers: combining an aluminium jaw coupling hub with a cast iron one

Can an aluminium hub be combined with a cast iron hub?

Yes, if both belong to the same coupling size and work with the same insert.
