UCP215 Pillow block bearing

UCP215 Pillow block bearing 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.
