linearstop is designed for use with linear movements. It can be used wherever a piston rod is available or can be additionally attached. It prevents unintentional sinking or falling of gravity-loaded axes.
The ROBA®-linearstop in electromagnetic and hydraulic versions are designed as clamping units and are suitable for EMERGENCY STOP braking. The pneumatic version Type 381.1 is also suitable for dynamic braking.

The ROBA®-linearstop is an electromagnetic, pneumatic or hydraulic safety brake.
In the de-energised state, a spring acts on a clamping element. The piston rod is clamped.
When the required operating pressure is applied or a voltage is applied, the clamping element is pushed or pulled against the spring. The piston rod can be moved.
