Blindly choose lubricants: Lubricants act to lubricate, cool, clean and seal. The quality of the lubricant is directly related to the length of the engine life. Blackening of the engine oil is the deterioration of the engine oil
Answer: 1) Metal materials, such as high-strength brass, tin bronze inlaid graphite bearings, etc. 2) Porous metal material (powder metallurgical material). 3) Non-metallic materials (nylon, polytetrafluoroethylene).
Answer: Oil-free lubrication bearings are a type of plain bearings. Generally, the sliding bearing needs to add lubricants such as lubricating oil and grease before working, so as to form a lubricating film on the friction surface to effectively lubricate
Main Products: Copper sleeve, graphite copper sleeve, self-lubricating copper sleeve, sliding bearing, composite bushing
