RUKO KEB-HM-53.0mm Hydraulic Clamping Element

Hydraulic clamping elements often struggle with reliable torque transmission and precise centering in demanding drive technology applications. The RUKO KEB-HM-53.0mm solves this by using hydraulic pressure to create a friction-locked, self-centering connection between shaft and hub, eliminating the need for keyways.

Who is it for

Engineers and maintenance professionals in drive technology who need a robust, low-maintenance shaft-hub connection that can be mounted and dismounted quickly without special tools.

Main features

• Hydraulic clamping principle for high clamping force and easy assembly
• Self-centering design ensures concentricity and reduces vibration
• No keyway required, simplifying shaft and hub preparation
• Low maintenance with no periodic re-tightening
