The non-positive shaft-to-hub connection. A zero backlash, frictional connection for hub bodies and hollow shafts.
Lightweight 3-piece version for medium torques. The slim design makes it ideal for thin hubs and hollow shafts.

Standard 3-piece version for high torques. Universal applications.

Large 3-piece version for very high torques. Larger version of the RfN 4061.

Small 3-piece version for low torques. Very low inertia due to the lightweight design.

Heavy-duty 3-piece version for maximum torques. Highly robust for extreme loads.

Standard 2-piece version for high torques. Wide range of applications.

Extremely slim versions for universal applications.

Identical to the RfN 7012, but optimised for extreme loads.

Transmits high combined forces and moments. Very good centring capability.
