Solid Lubrication Self Lubricating Bimetal Bearing Bushing Filled With Graphite
1. Product Description
Solid Lubrication Self Lubricating Bimetal Bearing Bushing Filled With Graphite is a kind of steel lead bronze alloys based with CuPb10Sn10 or CuSn8Pb10 bearing which is embedded with particular formulation of solid lubricants.Owing to the high strength, high load capacity and the spirally distributed diamond embedded with solid lubricant.With an lubrication area of 25% on the bearing surface up to,the bushing shows the better performance in good lubrication and anti-wear.

3. Application
Solid Lubrication Self Lubricating Bimetal Bearing Bushing Filled With Graphite is widely applied in metallurgical machinery,crane,automobile ,electric generator etc.
4. Advantages
Solid Lubrication Self Lubricating Bimetal Bearing Bushing Filled With Graphite to decrease abrasion,the surface of alloy is machined with diamond shape sockets in which particular solid lubricant is filled. When necessary,the steel back can be plated with an anti-erosive coating. It's fit for applications in higher temperature and the water or other conditions that is impossiable or diffucult to add oil.It's Load capacity rather high.
