JDB-600 product description
JDB-600 pure copper oil groove bearing is a high-strength brass bearing lubricated by oil-to-oil oil. This product has the function of traditional tin bronze bearing. Since the high-strength brass is used, its hardness is doubled, so using this product in low-speed occasions can double the life of ordinary bronze bushings, and its bearing pressure is large. , which can be used in heavy-duty situations.
