The jdb-1u oil groove copper sleeve is a high-strength brass bearing with oil gutter oil as lubrication. The product has the function of traditional tin bronze bearing, as a result of high brass, its hardness is doubled, so in the case of low speed using the product, bronze bushing life can extend one times than normal, and the bearing pressure, can adapt to overload situations. At present, the product is mainly used in the mechanical joint part of the excavator and the large gearbox.
