In conventionally lubricated bronze materials a„separating lubricating film“ can only be formed if themovement conditions and sliding speeds are suitable.With self-lubricating bearing, the lubrication is provided by thesliding material itself. The solid lubricant is released from the bearing material by micro abrasion as soon as thesliding movement begins. This gives the sliding partnerssmooth surfaces with a firmly adhesive solid lubricantfi lm. The solid lubricant remains within the contact zoneeven under heavy loads, resulting in a high degree ofseparation between the sliding surfaces and a sustainedlow coeffi cient of friction coupled with minimal wear.
