modern-day bearing materials. Zero maintenance is often expected under severe to extreme conditions as well as under maximum loads.
The constant pressure on costs also calls for increasing uptime of machinery and equipment and uncompromising standards of operational reliability. materials are suitable for applications involving sustained high static and dynamic loads,relatively low sliding speeds and rotary, angular, axial or linear motion. They are also suitable for applications where conventional lubrication is not possible or permissible, or where other properties are required such as durability and resistance to operational and environmental or special conditions (e.g. impact load, abrasive stress, etc).
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.
