Rail brakes
RB Series spring-engaged rail brakes use springs to secure load in holding applications, offering superior response time and high stopping and holding force for e-stop and power-off situations.
Features & benefits
-
Brakes maintain accurate positions on the center of guide rails for positive braking and holding in all axes, eliminating drivetrain backlash and elasticity
-
RBE Series electric rail brakes provide fast response, low backlash, plus onboard control logic for electric holding on profile rails; microcontroller receives and sends engage/disengage signals to drive, without an externally mounted controller
-
RB Series offers brake geometry similar to system bearing cassettes
-
Both series fit most profile guide rails including NSK, SKF, INA, THK, IKO, Hiwin, and Star

Stainless steel permanent magnet clutches and brakes
Suitable for harsh washdown environments, Warner permanent magnet clutches and brakes feature all stainless-steel construction and operate without electricity.
Features & benefits
-
Because torque is independent of slip speed, torque is smooth from 1 to 1,800 rpm
-
Extremely smooth slip torque provides constant torque for tension or torque-limiting applications
-
Dependable performance, with no friction surfaces to break down or wear out; 400 Series stainless-steel bearings for long life
