Outer spherical bearing with top screw
The spherical ball bearing with top screw produced by our company includes UC200 series (light series), UC300 series (heavy series) and its deformation product SB (UB) 200 series. There are two jackscrews on this type of outer spherical bearing, with an included angle of 120 °. Its feature is that when cooperating with the shaft, the jackscrew is used to jack the shaft, and then has a fixed effect. Its operating environment requires a small oscillation scale. It is applied to the through-shaft with large rigidity difference and deflection. The bearing is equipped with sealing rings on both sides, which can strictly prevent dirt invasion. When leaving the factory, an appropriate amount of lubricant has been filled. Before installation, it is not necessary to clean and add lubricant. UC200 bearing is the most widely used type of outer spherical bearing. It can be used with various types of bearing blocks on a variety of machines. UC300 series can bear larger loads than UC200 series coaxial diameter size, and it can be used with various types of bearing blocks on a variety of machines with larger loads.
