Bronze bearing with solid
modern-day bearing materials. Zeromaintenance is often expected under severe to extreme conditions as well asunder maximum loads.
The constant pressure on costs also calls forincreasing uptime of machinery and equipment and uncompromising standards ofoperational reliability. materials are suitable for applications involvingsustained high static and dynamic loads,relatively low sliding speeds androtary, angular, axial or linear motion. They are also suitable forapplications where conventional lubrication is not possible or permissible, orwhere other properties are required such as durability and resistance tooperational and environmental or special conditions (e.g. impact load, abrasivestress, etc).
In conventionally lubricated bronze materialsa„separating lubricating film“ canonly be formed if themovement conditions and sliding speeds are suitable.Withself-lubricating bearing, the lubrication is provided by thesliding materialitself. The solid lubricant is released from the bearing material by microabrasion as soon as thesliding movement begins. This gives the slidingpartnerssmooth surfaces with a firmly adhesive solid lubricantfi lm. The solidlubricant remains within the contact zoneeven under heavy loads, resulting in ahigh degree ofseparation between the sliding surfaces and a sustainedlow coefficient of friction coupled with minimal wear.
