22318 CC W33 Roller Excavator Bearing
Roller Bearing 22318 CC W33 With Excellent Roller Bearing Lubriion
Bearing Details
Roler bearing 22318 CC W33 with excellent roller bearing lubriion design & concept :
Shaker Screen Bearings spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.
It has two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. They are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
Spherical Roller Bearings dimensional series are:
Inspection of bearing and judgment :
In order to determine whether removing bearings can be used to check after the bearings clean, carefully check the roller surface, scroll, status of the mating surfaces, wear of the cage, the increase in bearing clearance and there's no falling damage, abnormal size precision. Non-separation of small ball bearings, supporting inner rings with one hand horizontally, rotate the outer ring to confirm in a smooth rotation State. Tapered roller bearings are separable bearings, rolling element and the Raceway in the outer ring can be respectively checked. Larger bearings cannot rotate, check rolling element and the Raceway, cage, sidewall surface appearance. the importance of as high as possible shall be carefully inspected.
Tips : Spherical roller bearing suffix meaning :
