Available in sizes from 15–65 mm, Generation II Profile Guide Rail Brakes provide fast engagement at 0.049–0.230 seconds and static holding force to 764 lb. Spring-engaged/air-released units offer stiffness and eliminate vibration in linear drives. Large clearance between brake and rail compensates for installation misalignment. With low backlash, maintenance-free brakes are suited for power-off, e-stop, and position holding applications.
