The task of the chain tensioner is to tension the timing chain in all operating conditions and to intercept unwanted vibrations even if wear elongation of the chain has occurred due to engine operation.

Quality is of enormous importance with this important component. This is why chain stretchers are precisely manufactured by bilstein group Engineering. Part of our chain stretchers are manufactured in our in-house production near the company headquaters in Germany on modern, CNC machines.

This ensures quality “Made in Germay”.
