About contact angle angular contact ball bearing:

单列角接触球轴承,适合to work in lower operating temperature and high speedwith a heavy thrust load. Can be mounted in a duplex arrangement. The refined bore tolerance give a higherlife.
Double-row angular contact ball bearing - excellent axial and radial rigidity in confined space.
Angular Contact Ball Bearings with contact angles of 15° (Symbol C) and 25° (Symbol A5) are primarily for high precision or high speed applications, and machined brass or synthetic resin cages or molded polyamidecages are used.

Application of contact angle angular contact ball bearing：
Single row angular contact ball bearing spindle, high frequency motor, gas turbine, centrifugal separator, the small car front differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, welding machine, low noise cooling towers, electrical equipment, coating equipment, machine bed plate, arc welding machine.
