Spring engaged, e-stop rod clamping element

Nexen’s RB Series of linear profile guide rail brakes uses spring force to secure the load in holding applications. They offer superior response time and high forces for e-stop and holding in power-off situations. The RB brake clamps directly onto the sides of the guide rail to provide positive braking and holding in all axes.  These profile rail brakes hold position accurately, eliminating drive train backlash and elasticity.

Warning: If personnel safety is required, an unrelated, redundant safety system is recommended.  Brake holding force should be checked after each dynamic stop.

Fits profile guide rail sizes 15, 20, 30, 25, 35, and 45

Holding forces up to 2600N 

  • Spring engaged, air released for power-off, e-stop and holding applications
  • Configurations  for Hiwin, NSK, Schneeberger, SKF, IKO, INA, Star, THK
  • Brake geometry is similar to system bearing cassettes for easy installation
  • Low backlash for accurate position holding
  • Adjustable facing gap for optimum brake performance
  • Field serviceable friction facing replacement
  • Large friction facing contact area
  • No lubrication or periodic maintenance required
  • Provides stiffness and eliminates vibration in linear applications
