In the case of large chains, or chains which are provided with additional interfering contours such as driving elements or support lugs, these are only conditionally suitable. Because the brush bristles are strongly deflected by passing, they wear out in a very short time.
Lubricating brushes with long bristles are able to withstand constant flexing movements for a considerably longer time, thus considerably expanding the field of application of lubricating brushes.
The use of VA spring elements on oil brushes with particularly long bristles keeps the entire brush flexible and adaptable without excessive spreading of the bristles.
In addition, the high-quality, corrugated bristles of the extra-long STW lubricant brush have a significantly increased oil holding and holding capacity that improves the “buffering” and even release of the lubricant.
