Profile Rail Brake

Nexen’s RB Series of linear profile guide rail brakes uses spring force to secure the load in holding applications. Superior response time and high force for stopping and holding in e-stop and power-off situations. Each RB brake clamps directly onto the centre of the guide rail to provide positive braking and holding in all axes, with no effect on bearing surfaces. These profile rail brakes hold position accurately by reducing drive train backlash and elasticity.

Nexen’s RB Series is engineered for dependable performance. With a revolutionary set of patent pending features, the RB Series provides an industry leading braking solution for linear profile guide rails. If personnel safety is required, an unrelated, redundant safety system is recommended.
