EAS®-compact®: The backlash-free, load-disconnecting torque limiter

Load-separating
Stepless torque adjustment
Backlash-free
High switch-off and repetitive accuracy
Automatic re-engagement

The EAS®‑compact is a positive-locking, ratchetting, or disengaging torque limiter based on the ball-detent principle. The clutch protects the drive line from excessively high, unpermitted torque impacts which can occur due to unintentional blockages.

Function with ratchetting/synchronous

If the set torque is exceeded (overload), the clutch disengages, and there is a residual torque of approx. 5 – max. 15 % of the set torque. When the overload is taken away, the clutch engages in the engagement position itself.
