Compared with other ordinary bearings, outer spherical ball bearings have another feature: double sealing, because the use of outer spherical ball bearings is generally harsh environmental conditions, especially agricultural machinery bearings, and double sealing ensures that dust is not easy to enter the inside of the channel. In the last two years, some companies have developed three-lip sealed outer spherical bearings, which greatly strengthen the dustproof ability. The service life of the bearing is extended.

A Pillow Block Bearing is a mounted anti-friction bearing that is contained within a solid cast iron, ductile iron or cast steel housing unit. Also referred to as a housed bearing unit, meaning they are self-contained, greased, sealed and ready for installation on the equipment.

pillow block ball bearing consist of a single-row ball bearing and an extended inner ring. They carry radial, axial and combination loads. The extended inner ring slips onto the shaft and secures with a locking mechanism.

Pillow block bearing , namely outer spherical bearings. It belongs to the deep groove ball bearing, inside the rolling body for the steel ball; Its outer ring surface is spherical, so it is called pillow block bearing.

The pillow block ball bearing is composed of a single row of deep groove ball bearings with seals at both sides and spherical outside surface, and a housing, suitable for simple support. UC series pillow block bearings are widely used in textile machinery, ceramic machinery and other manufacturing industries.
