Linear pofile guide rail brakes deliver high holding

Paul Boughton
Nexen Group is introducing the RB Series, Generation II linear profile guide rail brakes for stopping and holding in emergency stop and power-off situations. RB Series brakes are claimed to deliver the highest spring-engaged/air-released holding force on the market, providing secure holding and a fast response time for a broad range of linear motion control applications. Each rail brake clamps directly onto 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 provides for dependable performance and minimises rail wear.
According to the Nexen Group, RB Series brakes are engineered for easy installation and use, as well as dependable performance. Brakes fit most popular profile guide rails, including those from: NSK, SKF, INA, THK, IKO, Hiwin and Star. No lubrication or periodic maintenance is required, and the static holding cycle life is in excess of one million cycles. If personnel safety is required, an unrelated, redundant safety system is recommended.
