UCT313 Pillow block bearings

UCT313 Pillow block bearings It consists of two sealed outer spherical ball bearings and a cast (or stamped steel plate) 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 bearing inner ring is fixed on the shaft with the top wire, eccentric sleeve or tight sleeve, and rotates with the shaft.
