Product Description

Water pump bearings are double-supporting auto bearings with a simplified structure. They have no inner ring for the two supporting bearings. They feature a groove for a rolling element directly made on the shaft, and the outer rings of the two bearings made to a unity and two sides of the bearing closed by rubber seals. Water pump bearings consist of primarily two design types: 1) The ball-ball featuring two rows of balls, and 2) the ball-roller featuring one row of balls (a one-row roller). In the condition of same loading capacity, the radial dimensions are usually lower than those of same kind; while in the condition of same radial dimensions, the loading capacity is usually heavier.
