ROLLED BRONZE - METRIC FLANGES WITH DIAMOND INDENTS

ASB’s line of rolled (wrapped) bushings is produced with diamond shaped lubrication indents on the bearing surface(s). These bushings are ideally suited for thin wall applications. The indents provide lubricant reservoirs that allow for excellent and prolonged service. 

For applications that are sealed or difficult to maintain, we also manufacture this product with self-lubricating graphite filled diamond or circular indents.
