Oilless bushes are also referred to as self lubricating bushes or bearings. that does not require traditional oil or grease lubrication. Instead, they use a variety of materials and designs to provide lubrication and reduce friction. Oilless bushes have become an important part of various industrial applications because of their ability to perform effectively without external lubrication. This is a revolutionary innovation in the field of mechanical engineering. The Oilless bushes provide an excellent alternative to lubricated bearings, reducing maintenance and operating costs while improving overall performance. Material for Oilless Bushes These bushes are typically made from a variety of materials, including: Porous Bronze Porous bronze bushes are made from a sintered bronze material that has been impregnated with a solid lubricant, such as graphite or PTFE.
