Straight Column Graphite Brass Copper Bushing JDB 4X6X6 Guide Sleeve Oil Free Bushing
JDB 4*6*6 Straight column graphite brass copper bushing;Plain
Bearing Bush Inlaid Sliding
JDBsolid inlaid bearing is on a high force brass substrate. A high performance solid lubrication product inlaid with graphite or MoS2 solid lubricant. It breaks through the limitation of general bearing relying on oil film lubrication. In the process of use, through friction heat to make solid lubrication and shaft friction, the formation of oil, powder coexist lubrication excellent conditions, not only protect the shaft does not wear, and make the solid lubrication characteristics eternal. Its hardness is twice as high as the general copper sleeve, and its wear-resisting performance is twice as high.
At present, the products have been used in metallurgical caster, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed and heavy load occasions.
