WB07486 Water Pump Bearing

Water pump bearings basically consist of standard double row bearings, ball-ball type and ball-roller type. Water pump bearings do not have an inner ring but instead have raceways directly machined into the shaft. Therefore, there is additional space for rolling elements enabling higher specific load-carrying capability than conventional single bearings. Water pump bearings can support both large axial and radial loads. The high load carrying capacity and high rotation speed enable the large flow of the water pump.

Water pump bearings are well greased and sealed to ensure high dependability. And the ends of their shaft normally extend beyond the outer ring on both sides. The length and diameter of these extended sections can be matched to the specific application. They are predominantly used in automotive water pump.

Description
water pump bearings are simple and affordable; they can have either two rows of ball bearings or one row of ball bearings and one row of roller bearings, each well-spaced to ensure a longer life and their capacity to withstand higher radial loads.

Advantages
The bearing is pre-lubricated with water-repellent grease which eliminates the need for maintenance, and is subjected to a special heat treatment during its production.

Special technical features
A shaft, which protrudes on both sides, is used instead of an inner ring, with the pulley mounted on one side and the pump impeller on the other.
