Mini Bearings0 pages

Produced to meet the high performance needs of business machines, offi ce equipment and other light duty mechanical applications, these bearings are supplied to leading OEM manufacturers worldwide.The majority of BNL mini bearings are manufactured from acetal (POM) fi tted with either stainless steel or carbon steel balls. A semi-crystalline material, acetal delivers excellent long-term wear performance and is dimensionally stable when subjected to load, temperature and most fl uids including detergents, fuel/oils/greases, brake fl uid, alkalis (pH9), alcohols, aliphatic/aromatic hydrocarbons, and acetone. Resistance to bleach and ketones is also possible, dependent on concentration. In addition, these bearings are lightweight, require no external lubrication, operate in temperatures from -40c to 100аc and offer lower friction at higher speeds. With fully moulded inner and outer races, BNL moulded bearings offer a greater life expectancy than similar bearings with machined races. Flanged options offer a fully integrated feature for accurate axial positioning. BNL (UK) Ltd offers a range of miniature plastic bearings designed to directly replace steel bearings in many demanding long-life light-load applications.
