By using clamping levers with integrated clamping force intensifier, the clamping force can be increased by up to 75% compared to standard clamping levers.

Furthermore, this product can also be used by persons with limited hand strength (e.g. in rehabilitation) to achieve comparable clamping forces with less effort. Less effort is also needed to loosen the clamping lever.

The increase in clamping force is achieved by the integral needle roller thrust bearing, which generates very low surface friction on a rigid contact surface during clamping. The hardened thrust washers are designed for high clamping forces and the bearing with its high load rating guarantees a long service life.

The clamped component is permanently protected by the large, stationary contact surface. A washer is no longer required.

Due to the modular construction many special designs are available.

Handle fibreglass reinforced plastic with die-cast zinc toothed ring.
Steel parts grade 5.8.

Steel parts black oxidised.
Axial needle bearing with hardened and ground thrust washer.

The handle lever is engaged in the toothed insert by means of a toothed ring when not actuated, enabling the thread to be tightened or loosened. By lifting the handle, it can be repositioned and re-engaged in the toothed ring by spring force.

Machine, equipment and plant construction, rehabilitation sector.

The screw-in depth must be at least 2 x the thread diameter and the thread should be lubricated lightly during installation.

Significant increase of the clamping force with the same tightening torque.
High quality axial needle bearing with high load rating and long service life.
The component surface is protected by the stationary lower ring.
