Water pump bearings

Water pump bearings is a double supporting bearing with a simplified structure, which constitutes no inner ring for the two supporting bearing, groove for rolling element directly made on the shaft, the outer rings of the two bearings made to a unity and two sides of the bearing closed by rubber seals.In the condition of same loading capacity, the radial dimensions are usually smaller than those of same kind; while in the condition of same radial dimensions, the loading capacity is usually heavier. Because of its good steel capacity and easy rotation and structure, they are used by many developed countries including USA, Japan, Germany and so on.

Water pump bearings are double row bearings and, in contrast to conventional double row bearings, do not have an inner ring but raceways machined directly into the surface of the shaft. As a result, there is more space available for the rolling elements, giving a higher specific load carrying capacity than that of solutions with conventional single bearings.

Furthermore, it is possible in this type of bearing to achieve economical combinations of ball and roller rows. In a small design envelope, this gives a broad range of load carrying capacities. The use of a common outer ring for two rows of rolling elements prevents misalignment defects, eliminating the risk of undesirable distortion of the bearings.

Automotive Water pump bearings is the most important part of the water pump. Because the high speed of revolution, usually it reaches 10000rpm/min, it requires the high-load ability of water pump bearing. And only this can keep the life of bearing under the high speed revolution.

The sign of a damaged water pump bearing can come in one of several ways. A squealing sound is a common sound of a failing water pump bearing, however, many bearings have been known to go bad without making a sound. Often, a bad water pump bearing will be noticed by leaking coolant coming out of the bottom or the backside of the water pump. In this event, it is time for a new water pump or a rebuild for the existing pump. In some circumstances, a rebuild kit is not available for the water pump, so a new water pump must be installed when the bearing goes bad in the existing pump.

Water Pump Bearings are mainly used in the automotive cooling pumps, in which the bearing unites replace the original two sets of single axial bearings. The product series includes two types: one is two rows of balls, and the other is one row of ball, one row of roller, which mainly endures radial load. The small loading bearing adopts the two rows of balls, and the product with large loading chooses the structure of one row of ball, one row of roller.
