RUKO KEB-HM-42.0mm Quick-In Clamping Bush

The RUKO KEB-HM-42.0mm Quick-In clamping bush delivers a keyless friction-fit connection for shafts and hubs, eliminating the need for keyways and enabling precise, backlash-free torque transmission. Its self-centering design and high transmissible torque make it a reliable alternative to conventional keyed connections in drive technology and general mechanical engineering.

Highlights

• Keyless friction-fit mounting principle
• Self-centering for accurate shaft alignment
• Transmissible torque: 1150 Nm
• Axial force capacity: 24 kN
• Four clamping screws for uniform radial pressure

In daily use

Mounting is straightforward: slide the bush onto the shaft, position the hub, and tighten the four clamping screws to the specified torque of 25 Nm. The resulting surface pressure of 110 N/mm² on both shaft and hub ensures a secure, backlash-free connection. Recommended tolerances are h8 for the shaft and H8 for the hub bore. The bush is supplied oiled for corrosion protection during storage and transport.
