Nexen’s Safety Rated Rail Brake Series of linear profile guide rail brakes use 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 Rated Rail Brake clamps directly onto the guide rail to provide positive braking and holding in all axes, with no effect on bearing surfaces.

Key features include:

Large friction-facing contact area for consistent performance and low rail wear
Ideal for power-off, e-stop, and holding applications
Low backlash for accurate position-holding
Brake geometry is similar to linear bearing cassettes for easy installation
Provides stiffness and eliminates vibration in linear drives
Large clearance between brake and rail compensates for installation misalignment
No lubrication or periodic maintenance required
Models available to fit most common profile guide rails
The highest spring engaged /air-released holding force on the market
Long-rated life (B10D) of 4 million cycles

Optional operating mode sensors
Optional operating mode sensor(s) are available to signal Engagement, Disengagement, or Wear. By using the Operating Mode Sensors, system manufacturers can gain higher safety category ratings per ISO 13849-1. Rating of the overall safety channel is the responsibility of the system manufacturer. Nexen’s sensors are also Industry 4.0 compatible and can provide information to maximize machine efficiency.
