Crusher copper sleeve

Characteristics and Applications

The product is environmentally friendly and recoverable copper sleeve. This product is based on excellent electrolytic copper, matches tin ingot and lead ingot in proportion to national standard. It has strong wear resistance and self lubrication. It can show excellent flexibility under the load of high speed rotating and swaying motion. It is the first choice for high speed operating machinery.
