UCP217 Pillow block bearings

UCP217 Pillow block bearings  In order to distinguish whether the removed pillow block bearing can be used from scratch, it is necessary to check its standard accuracy, rotation accuracy, internal clearance and wear conditions of the cooperating surface, raceway surface, holder and seal ring. Regarding the inspection effect, it can be distinguished by the conventional bearing or the reasonable user who knows the bearing, and the inspection cycle and detection parameters can also be different according to its mechanical function and the importance of related factors. If the above damage can not meet the requirements for re-use, the bearing shall not be used from scratch, and it is necessary to replace it. The outer spherical bearing of the pillow block bearing consists of two outer spherical ball bearings with sealing on both sides and a cast (or steel plate stamping) bearing seat. The internal structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the inner ring of this bearing is wider than the outer ring. The outer ring has a truncated spherical outer surface, which can be automatically aligning when matched with the concave spherical surface of the bearing seat. Usually, there is a gap between the inner hole of this bearing and the shaft, and the inner ring of the bearing is fixed on the shaft with the top wire, the heart, the sleeve or the tight sleeve, and it rotates with the shaft.
