Marble static pressure sawing work environment is poor, product requirements of high reliability, long life, maintenance difficulties; in order to meet the marble static pressure saw manufacturers to turn the use of parts and life requirements, we recommend customers to use self-lubricating Bearing products; self-lubricating bearing products using centrifugal casting high-strength copper alloy as the matrix, and then finishing. Self-lubricating bearings are suitable for use on marble static pressure saws. Compared with ordinary copper sets of products, high-strength copper sets are more suitable for harsh working environments, high load, impact resistance, higher reliability and long service life. long.
