BR7 series products
BR7 steel back lubricated decentralized bearing
BR7 steel back lubricated dispersed bearing is a composite bearing composed of porous special oil-bearing wear-resistant material and metal steel back.
The special wear-resistant layer is made of special copper alloy powder and solid lubricant mainly composed of graphite by dispersion and sintering at high temperature. It is treated with oil to obtain excellent friction and wear properties.
Metallographic analysis
1. Made of porous special oil-bearing wear-resistant material
2. Metal layer steel back
Product characteristics&Application area
Product characteristics
- 1. In any direction of free movement, due to the uniform dispersion of solid lubricant, it has high performance and even very small movement can be applied;
- 2. Apply to self lubrication state;
- 3. High load bearing, excellent wear resistance, excellent speed characteristics;
- 4. Standard products and plates of various specifications can be provided for secondary processing.
Application area
- At present, it has been widely used in the sliding parts of various machines, such as automatic mechanical equipment (telescopic, swinging, sliding, bending, whirling, rotary parts), hydraulic cylinder guide sleeve, gear pump, textile machinery, vending machine, plastic molding machine, die-casting machine, rubber machinery, tobacco machine, fitness equipment, office machinery, hydraulic carrier, automobile, motorcycle, agricultural and forestry machinery, etc。
