Backlash-free all-steel coupling ROBA®-DS type 951.881
Mayr Japan LLC
About This Product
ROBA®-DS transmits drive torque up to the rated torque completely backlash-free and with consistently high torsional rigidity. There is no disk flexing or friction bond separation that occurs with commercially available couplings. Shaft misalignment allows 100% of the rated and peak torque to be utilized without affecting the transmitted torque. This ensures unrestricted usage.
■Technical features
・Unaffected by alternating loads up to 100% of rated torque
・Low mass inertia due to highest power density
・Completely backlash-free up to rated torque
・Low restoring force, high misalignment correction ability
・High torsional rigidity up to rated torque
- Absolutely no wear and maintenance free
・Optimal design with abundant variations
