Backlash-free

The backlash-free, highly rigid ROBA-guidestop profiled rail brakes are claimed to guarantee maximum safety. In machine tools and machining centres, they additionally increase the process accuracy and machining performance.

The ROBA-guidestop brakes are directly mounted onto the masses to be braked or held. This creates a decisive advantage, especially for gravity-loaded axes, where the hazard risks to people must be minimised: Drive elements between the motor and the moving mass such as spindles, spindle nuts, shaft couplings or gearboxes, have no influence on safety – this differs from concepts featuring a motor brake, in which all drive elements transmit the braking torque up to the carriage.
