Friction Locking Sleeves

Precision locking at any stroke position.

Hydraulic applied locking device for reciprocating hydraulic actuators. They can be 'built in' to new actuators or fitted over an extended piston rod.

Prevents axial motion;slippage release of overload, re-locking after load reduced.

The locking force is proportional to applied pressure and the lock releases on venting pressure.

Unique highly space efficient design giving improved power density.

Suitable for double acting and single acting cylinders, and other shaft locking applications.
