LINEAR MOTION CONTROL
Technical Data Sheet

Profile Rail Brake, Generation II
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 center 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.
•t Large friction facing contact area for consistent performance and low rail wear
•t Field serviceable friction facing replacement
•t Ideal for power-off, e-stop and holding applications
•t Low backlash for accurate position holding
•t Brake geometry is similar to linear bearing cassettes for easy installation
•t Provides stiffness and eliminates vibration in linear drives
•t Large clearance between brake and rail compensates for installation misalignment
•t No lubrication or periodic maintenance required
•t Models available to fit most common profile guide rails
•t Highest spring engaged / air released holding force on the market
•t Static holding cycle life in excess of one million cycles
