KTR-STOP® NC passive, spring-operated clamping system

Clamping system for cylindrical shafts and piston rods

The KTR-STOP NC series is a passive clamping and braking system serving for generating a clamping/braking force or clamping/braking torque on a cylindrical piston rod or shaft to delay or brake its rotation or keep it at standstill.

The KTR-STOP NC clamping system offers added safety, firstly by means of the clamp force it supplies and the installed fail-safe function; secondly, the system absorbs axial loads thereby preventing damage to the powertrain.

Application areas of our spring-operated clamping system KTR-STOP NC:

Thanks to the multifunctional nature of this system, the passive clamping can be used both on linear drives and also as a stop system in machine tools, robots and the field of general mechanical engineering.
