Bronze bearing with solid 
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.
现代轴承材料设计要求产品应用在零维护及预计经常在恶劣较端条件以及较大负荷下。成本压力不断加大的同时还要求机械设备增加正常运行时间，严格标准的运行可靠性，此型号产品的润滑材料全部集中在轴承的内径表面包裹旋转轴，既能较大限度的保留轴承的承载力又较大的满足了工况的润滑要求，材料适合应用涉及持续的高静态和动态负载。
能相对降低的滑动速度摩擦力，可以用于旋转，角度，轴向或直线运动。润滑是由提供滑动材料本身提供的，只要运转开始固体润滑剂就会通过微磨损的轴承材料来释放，润滑剂保持接触的区域内的甚至在重负载下，高性能的滑动表面和一个持续之间的分离低摩擦系数可以保证轴承的磨损量在非常小的范围内。
