There are many kinds of bearing materials, of which there are commonly used carbon steel, bearing steel and iron; there are not commonly used stainless steel, plastics, nylon, aluminum alloy, etc.
1: Shell
2: Joint ball
3: Ring
4: Liner or nozzle
Self-lubricating centripetal joint bearing (spherical surface of inner ring chrome plated), copper ring gasket, and threaded extension bar (galvanized surface). Joint bearing is classified according to the lubrication state into self-lubricating (without nozzle) joint bearing and padded (with nozzle) joint bearing; it can be classified into right-handed joint bearing and left-handed (add "L" symbol for the left-handed) joint bearing based on the direction of thread; according to the fitting location of thread, it is classified into inner thread joint bearing and outer thread joint bearing.
