JDB-2 product description
JDB-2 bronze lubricated inlaid bearing is a solid lubricating product with 6-6-3 bronze as matrix, embedded graphite and MoS2 as solid lubricant. Because the density of 6-6-3 bronze is higher than that of high-strength brass, it is very wear-resistant in the occasion of high temperature and low load.
