JDB - 650 Mosaic solid self-lubricating bearings: belongs to a series of sliding bearing, is in the high force brass (main chemical composition Cu Al Mn Fe Ni zinc percentage respectively: 60 ~ 66% 5.0 0.2 2.5 ~ 2.5 ~ 7.5% and 5.0% ~ 7.5% ~ 0.5% 22 ~ 28%) on the base of inlaid graphite or a high-performance solid lubrication MoS2 solid lubricant products.It broke through the general bearing on the limitations of the oil film lubrication.In use process, through the friction heat make solid lubrication and shaft friction, the excellent conditions of forming, powder and oil lubrication, both to protect shaft wear and tear, and the solid lubrication characteristics of eternity.It is twice as tall as general copper sleeve, wear-resisting performance is twice as high.
It is recommended to use occasions:
Now the product has been used in metallurgical continuous casting machine, train bracket, steel rolling equipment, mining machinery, shipping, steam turbine and other high temperature, high load, etc of low speed and heavy loading.
