Star grips with integrated clamping force intensifier can achieve double the clamping force compared to standard star grips.
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 star grip.
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.
