Pillow block bearings

Pillow block bearings are mounted bearings that are used to provide load support for a rotating shaft��s axis. Their mounting surface is on a line parallel to the axis of the shaft. Elongated bolt holes in the base or feet of pillow block bearings permit adjustment and easy mounting. Product categories include plain bearings, ball bearings, cylindrical-roller bearings, needle-roller bearings, tapered-rolling bearings, hydrodynamic bearings, and more. With pillow block bearings, product selection is based on shaft size, radial and thrust load requirements, and dimensions and measurements.

There are several roller options for pillow block bearings, including cylindrical and needle. Cylindrical-roller bearings are pillow block bearings with high radial capacities and moderate thrust loads. They can be crowned or end-relieved for reduced-stress concentrations. Cylindrical-roller pillow block bearings produce low friction and allows for high-speed. Needle-roller bearings contain a needle roller. They are designed for radial load applications where a low profile is desired.
