Established in 1998, China Xiaowei Bearing Co., Ltd. is a high-tech enterprise specializing in water pump bearing manufacturer and design many kinds of bearings. We have a modernized staffs of tech research and fog machine development, ISO9001 certificated, and manufacturing adopts advanced domestic and foreign standards such as GB, API, JIS, DIN, BS, NF and ANSI.

a) Water pump bearings are used primarily in automotive water
pumps and basically consisted of standard double row bearings
b) Mainly exists two types design
1) Ball - ball: with two rows of balls
2) Ball - roller: with one row balls, one row rollers
The outer ring raceway of this bearing is spherical, with the center of the radius
located on the bearing axis, providing a self-alignment capability. This bearing
incorporates a 45o contact angle that enables the bearing to support large axial
loads and moderate radial loads. These bearings incorporate an improved
internal design that allows relatively high-speed operation. Typical applications:
injection molding machines, crane hooks, vertical pumps.
