Between 100 and outer ring 400.
The inner ring 100 includes the pedestal 110 and cylinder 120 of concentric setting；The pedestal 110 is arranged on cylinder 120
Upper surface；110 radial equipartition of pedestal has washer 111；The washer 111 is arranged at intervals；The bottom of the washer 111 is straight
Footpath is less than the internal diameter of outer ring 400；The top diameter of the washer 111 is more than the internal diameter of outer ring 400.Cleaning solution can be from washer
111 gap is flowed into working region between inner ring 100 and outer ring 400.The 120 hollow setting of cylinder, and cylinder 120 is outer
Side is provided with interior raceway 121.The radian of the interior raceway 121 is adapted with steel ball 200.
The retainer 300 includes retaining ring 301, holding rod 302 and the spacer ferrule 304 in annular shape being wholely set.
The retaining ring 301 is in hollow ring-type；The 302 equidistant axial arranging of holding rod in 301 side of retaining ring,
