RKSK 2020 and RKTK 2020 friction couplings
The RKSK 2020 and RKTK 2020 miniature friction couplings are the clamping hub variants for shaft-friendly installation.
Friction couplings protect a mechanical drive from failure due to the permissible torque being exceeded. The RKSK version is equipped with a spiral spring, the RKTK version with a disc spring, depending on the speed or torque. The slipping torque can be infinitely adjusted.
Important: The gear wheel shown here is not included in the scope of delivery! However, it can be manufactured to your requirements on request. Please compare our variants with RKSS/RKTS screw hubs.
