RUKO KEB-HSS-Mod.55 Self-Centering Clamping Element 55 mm Shaft Diameter

Self-centering clamping element for shaft-hub connections, delivering a friction-locked, keyless power transmission with high torque capacity. Its tapered ring design provides precise centering and reliable clamping force for industrial drive technology.

Advantages

Keyless shaft-hub connection eliminates backlash and simplifies assembly. The self-centering mechanism ensures concentric running and reduces setup time. High-strength steel construction withstands demanding torque and axial loads.

Suitable for

• Industrial drive systems requiring backlash-free torque transmission
• Applications with frequent assembly or disassembly of hubs
• Power transmission between shafts and hubs without keyways

Key specifications

• Shaft diameter: 55 mm
• Outer diameter: 90 mm
• Overall length: 40 mm
• Nominal transmissible torque: 1500 Nm
• Max. transmissible axial force: 30 kN
• Surface pressure on shaft: 150 N/mm²
• Surface pressure on hub: 150 N/mm²
• Number of clamping screws: 6
• Clamping screw size: M8
• Tightening torque for screws: 35 Nm
