ROBA® linearstop pneumatic: Pneumatic

As a safety brake for piston rods, the ROBA® linearstop offers unique possibilities for increasing the safety of machinery. It can be integrated into already existing machinery and system constructions easily, quickly and without extensive adjustment work and it is predestined for securing vertical axes. By combining the ROBA® linearstop with another brake, a redundant, multi-purpose braking system can be created comparatively easily. As the ROBA® linearstop brakes independently of the existing drive system, safety considerations are easier to make. The braking effect is independent of the movement direction; movement to release after braking is not necessary. The ROBA® linearstop is backlash-free, suitable for emergency stop braking and stands out thanks to its short switching times.
