 JDB-600 Oil groove copper liner

basic characteristic
JDB-600 Copper sleeve is a high-strength brass bearing lubricated with oil from oil grooves. This product has the traditional function of tin bronze bearings. Due to the use of high-strength brass (ZCuZn24Al6), its HB hardness has doubled. Therefore, when used in low-speed situations, the lifespan of this product can be extended by twice compared to ordinary bronze sleeves. Moreover, its load-bearing pressure is large and it can adapt to heavy-duty situations. At present, this product is mainly used in the load-bearing joints of excavators and large gearboxes.
