inset ball bearingGE25-XL-KRR-B with size 25*52*44.5mm ,this bearing are produce with Chrome steel material R seals on the both bearing sides ,and located with eccentric locking collar.
The code of Insert ball bearing with set screw is uc200 series (light series), uc300 series (heavy series) and UB (sb) 200 series. If the application environment is small, uc200 series is usually selected on the applications,, otherwise uc300 series is selected. Generally, there are two jackscrews on the spherical surface ball bearing, with an included angle of 120 °. The characteristic is that the jackscrew is used to Jack the shaft when cooperating with the shaft, and then it has a fixed effect. However, the cooperation environment needs to have a small oscillation scale.
