  • Pillow Block Bearing

    Pillow Block Bearing with seat is a bearing unit which combines rolling bearing with bearing seat. Most of the outer spherical bearings are spherical in outer diameter. They are mounted together with the imported bearing seat with spherical inner hole. They have various structures, good versatility and interchangeability.

    At the same time, this kind of bearing also has a certain degree of alignment in design, easy to install, with a double structure of sealing device, can work in harsh environment. Bearing seat is usually cast. Commonly used seats are vertical seat (P), square seat (F), convex square seat (FS), convex round seat (FC), rhombic seat (FL), annular seat (C), slider seat (T), etc.


    • It is not necessary to design another bearing box in use. It is small in size and simple in structure.

    • Simple and practical

    • Auto-adjustable

    • Annex Assistance

    • Small working environment requirements

    • Good rotation accuracy.


    Pillow Block Bearing ,Generally speaking, deep groove ball bearings with outer spherical bearings are easy to use, which are characterized by simple loading and unloading and adjustable alignment. The standard tolerances of outer spherical ball bearings are: adding and subtracting, adding tolerances to the inner diameter to ensure the lightness when matching with the shaft; each outer spherical ball bearing is not used alone.

    Outer spherical ball bearings have another characteristic than other ordinary bearings, which is double-layer seal, because the use environment of general outer spherical ball bearings is more harsh, especially for agricultural machinery bearings, and double-layer seal ensures that dust is not easy to enter the inner channel.

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring
