SF-2 product description
SF-2 carbon steel-based boundary self-lubricating bearing is based on steel plate, sintered spherical bronze powder in the middle, surface-rolled modified polyoxymethylene (POM), and contains an oil storage pit. It is suitable for low-speed and medium-load places under normal temperature conditions, replacing traditional copper sleeves to reduce costs and prolong service life. Used on rolling mills, it can save the frequency of refueling and simplify the replacement procedure.
