Adjustable hand levers GN 300.4 are produced with a clamping area which is linked via a thrust ball bearing to the bush and screw respectively of the clamping lever. This has led to the following advantages:
- Doubled clamping force through vastly reduced friction.
- There is no movement on the contact area between adjustable hand lever and component which greatly reduces any marking on the clamping area
- In addition a reduced creep factor has been achieved by the increased preload.
