2316 Self-aligning ball bearing

Self-aligning ball bearings are transmission components featuring automatic self-alignment capabilities, capable of compensating for installation misalignment between shafts and bearing housings (such as coaxiality errors). Suited for high-speed operation, they offer a compact structure, stable load-bearing performance, and straightforward maintenance. These bearings find extensive application in equipment including electric motors, pumps and valves, and construction machinery.
