Granite mills have poor working conditions, poor lubrication conditions, and are difficult to maintain; in order to meet the granite mill manufacturer's requirements for the use of rotating components and life requirements, our company recommends customers to use self-lubricating graphite copper sleeves and bimetals. Bushing products; self-lubricating graphite copper bushing products use centrifugal casting high-strength copper alloy as the substrate, the surface is inlaid with a special formulation of solid lubricants; bimetallic bushing products use the outer steel base, the inner surface is cast a layer of copper material and then refined Processing. Self-lubricating graphite copper bushings are suitable for use on granite mills. Compared to ordinary copper bushings, self-lubricating graphite bushings are more adaptable to harsh working environments, high load carrying, impact resistance, and higher reliability of use. It can be maintenance-free for a long time and has a very long service life. Bi-metal bushings are lower in price than copper bushings and can effectively reduce customer costs.
