High lead tin bronze sleeve

Characteristics and Applications

High lead tin bronze sleeve, wear-resistant self-lubricating copper sleeve, environmental protection recyclable copper sleeve. This product is based on excellent electrolytic copper as the base, matching the tin ingots and lead ingots according to the national standard ratio. In the absence of lubricants and water lubricants, it exhibits excellent sliding and self lubricating properties. Under the load of high speed rotation and rolling motion, the impact resistance is 50MPa, showing excellent flexibility. It is the first choice for high-speed running machinery.
