Detail

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.

Bearing seal:

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.

Concept：

The outer spherical ball bearing is actually a variant of deep groove ball bearing,characterized by its outer ring outer diameter surface is spherical, which can be fitted into the corresponding concave spherical bearing seat to play a role of self-aligning.
The outer spherical bearing is mainly used to bear the combined radial and axial loads mainly in the radial load, generally no suitable to bear the axial load alone.
The outer spherical bearing with seat is a kind of bearing element which combines the rolling bearing with the bearing seat. Most of the outer spherical bearings are made of spherical outer diameter and installed together with the bearing seat with spherical inner hole. The structure is diverse, and the versatility and interchangeability are good.
