Description

Pillow block bearing (puter spherical ball  bearing) is actually the deep groove ball bearing a form, characteristic is its  outer diameter for spherical surface, can match the bearing of the  corresponding concave spherical self-aligning effect within the outer spherical  bearing is suitable for the required equipment and parts of simple situation,  such as used for agricultural machinery, transportation systems or on  construction machinery.

It is mainly used to bear radial direction  load primarily radial and axial loads, and should not be commonly alone bear  axial load, the bearing can be installed separately inner ring (with full set  of roller and retainer) and outer ring. This kind of bearings are not allowed  to have inclined shaft relative shell, under radial load appointment will  generate additional axial force.
