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.

Pillow block bearing with seats are usually with bolts, which are convenient to be fixed in the place where they should be fixed. There are also slider type and frame type, which are fixed by clamping, and overhang type and suspension type, which are usually with threads, which are convenient to be fixed in the rod end or suspended in the air.

At the same time, this kind of bearing is also designed with a certain centrality, easy to install, with a double structure of sealing device, can work in harsh environment. The bearing seat is generally molded by casting. Commonly used seat is vertical seat (P), square seat (F), boss square seat (FS), boss round seat (FC), diamond seat (FL), ring seat (C), slide block seat (T).

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.

Application：

suitable for applications requiring simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery.
