54220 + U220 Double direction thrust ball bearings

Short Description:

Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low thrust applications where there is little axial load.

Double direction thrust ball bearings are able to accommodate axial thrust loads in both directions. They are not able to tolerate any amount of radial load.

These bearings consist of one shaft washer, two housing washers and two ball and cage assemblies.The housing washers and ball and cage assemblies of double direction bearings are identical to those used in single direction bearings.

can accommodate axial loads and locate a shaft axially, in both directions

The balls which are used as rolling elements in this type of bearing enable outstanding performance at the highest speeds.

These kind of bearings have a separable design to facilitate easy mounting, dismounting and bearing inspection. This also means that they are easily interchangeable.
