Tin Bronze Eccentric Bushing Crusher Machine Spare Parts For Ore Mining

Factory Price Crusher Machine Spare Parts Tin Bronze Eccentric Bushing

Product description​ :

Copper bushing is a part of mechanical equipment, which is mainly used in mining machinery and equipment, and it is widely used. In the application process of mechanical equipment, copper bushing is an indispensable part.

This product is based on the excellent electrolytic copper, and mixed with tin ingot and lead ingot according to the national standard proportion to form the high wear-resistant self-lubricating copper alloy material. Under the condition of lacking lubricant and using water quality lubricant, it shows excellent sliding and self-lubricating performance. Under the load of high-speed rotation and swing motion, the impact load resistance is up to 50MPa, showing excellent flexibility, which is the first choice of high-speed running mechanical equipment.
