Why do you choose the guide sleeve with bronze plus Shi Mozhu?
Under dry friction conditions, we design a pre - formed synovial membrane on the surface of the bearing to ensure that the solid lubricant is transferred to the dual parts in the shortest possible time, and an effective solid lubricant film is formed
With high strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4) as the basic material, according to the use conditions according to a certain proportion in the work surface processing hole and fill in the solid lubricant, copper alloy high strength provides high bearing capacity and solid lubricant can form low friction.
The mold guide sleeve is made of bronze graphite column because the mold bushing needs self lubrication, less fuel filling or less oiling
