GN300.4 Adjustable Hand Lever, High Force
These high force adjustable hand levers, GN 300.4, are produced with a clamping area which is linked by a thrust ball bearing (axial ball bearing) to the threaded bushing of the clamping lever. This results in several advantages. The clamping force is greatly increased and often doubled through vastly reduced friction. There is no movement on the contact area between adjustable handle lever and component which also greatly reduces any marking on the clamping area. In addition a reduced creep factor has been achieved by the increased preload.
