What is an  Water pump bearing?


Water pump bearings are designed to support large axial loads but can also support moderate radial loads. They incorporate an improved internal design that enables it to operate at high speeds.

These bearings have self aligning characteristics. This is because the outer ring raceway is spherical and the center of the radius is located on the bearing axis.



Unlike other double row bearings, water pump bearing do not have an inner ring but have raceways which are machined directly into the surface. This enables them to have more space available for the rolling elements hence improve its load carrying capabilities.

Due to its design, it is possible to use a suitable combination of both ball and roller rows economically.




Our water pump bearings can support heavy loads and are easy to install because they come as ready to fix units.
