UC200 series (light series), UC300 series (heavy series), and deformed product UB(SB)200 series, if the use environment is small, generally choose UC200 series, otherwise choose UC300 series. Generally, there are two jacking wires on the outer spherical ball bearing, and the included angle is 120°. Environmental requirements must have a small vibration range. This kind of outer spherical ball bearing is relatively common and widely used in textile machinery, ceramic machinery and other manufacturing industries.
