Spring-engaged rail brakes feature large friction facing area

01 October 2010

Nexen Group has introduced the RB Series, Generation II linear profile guide rail brakes for stopping and holding in e stop and power off situations. RB Series brakes deliver high spring engaged/air released holding force, providing secure holding and fast response time for a broad range of linear motion control applications.

Each rail brake clamps directly to the centre of the guide rail to provide positive braking and holding on all axes, with no effect on the bearing surfaces. RB Series profile rail brakes hold their position accurately by reducing drive train backlash and elasticity. The large, field-adjustable friction facing contact area allows dependable performance and minimises rail wear.


RB Series brakes fit most popular profile guide rails, including NSK, SKF, INA, THK, IKO, HIWIN and Star. No lubrication or periodic maintenance is required. If personnel safety is required, an unrelated, redundant safety system is recommended.
