Friction Locking Sleeves

Precision locking at any stroke positon.

Hydraulic applied locking device for reciprocating hydraulic actuators.

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.

Locking force proportional to applied pressure. Lock releases on venting pressure.

Unique highly space efficient design giving improve power density.

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