Spring steel sheets allow the chain lubrication pinions to be installed quickly and easily. A light preload ensures the continuous supply of lubricant. A further advantage of this type of installation is that the whole assembly can flexibly yield to fluctuations and vibrations. The spring steel sheet is available in both short and long versions and can be combined with an angled axle.

Mode of operation

The lubricant passes through the axle and appropriate holes in the foam material. With just a low pressing pressure, the stored lubricant is released again. The PU foam used (open-cell) stores the lubricant and releases it again in very small dosing quantities. In this way, over lubrication is effectively prevented, as it is possible wear caused by a lack of lubrication.
