Pillow block bearing consists of an outer spherical ball bearing with seals on both sides and a cast (or stamped steel plate) bearing seat.

The internal structure of a seated outer spherical ball bearing is the same as that of a deep groove ball bearing, but the inner ring of this type of bearing is wider than the outer ring. The outer ring has a truncated spherical outer surface, which can automatically adjust the center when matched with the concave spherical surface of the bearing seat. Usually, there is a gap between the inner hole of this kind of bearing and the shaft, and the inner ring of the bearing is fixed on the shaft with a jack wire, an eccentric sleeve, or an adapter sleeve, and rotates with the shaft.

The bearing with seat has compact structure, convenient installation, and unloading, perfect sealing, suitable for simple support, and is often used in mining, metallurgy, agriculture, chemical industry, textile, printing, and dyeing, conveying machinery, etc.
