Pressure spring

Stainless steel AISI 301

Adjustable hand levers GN 300.4 are produced with a clamping area which is linked via a thrust ball bearing (axial bearing) to the insert of the hand 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.
