Clamping for machinery and plant components
Locking units are used primarily as functional clamps for precision locking, but also for preventing unwanted movement.

locking unit design
The clamping system consists of a conical sleeve and a clamping ring with conical bore.
The sleeve is axially fixed in the housing, allowing only radial movement.The clamping ring is guided by the housing and forced over the sleeve in axial direction to clamp the unit.
The clamping force is generated by pressure or spring action and is intensified by means of conical surfaces.
In released condition, the clamping ring is pushed against the springs by the annular piston. A well-defined clearance ensures that the shaft can move without friction.
