Angular contact ball bearings can bear both radial and axial loads. Can work at higher rotation speed. The larger the contact Angle, the higher the axial carrying capacity. The contact Angle is the Angle between the contact point connection of the ball and raceway and the vertical line of the bearing axis in the radial plane. High precision and high speed bearings usually take 15 degrees of contact Angle. Under axial force, the contact Angle will increase.

Single row angular contact ball bearing can only bear axial load in one direction, when bearing radial load, it will cause additional axial force. And only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact Angle of 40 degrees, so they can withstand a large axial load.

Double row angular contact ball bearings can bear large radial load, mainly radial and axial combined load and torque load, limiting the axial displacement of two sides of the shaft. The inclinability between the inner and outer rings of the double row angular contact ball bearing is limited in the parts mainly used to limit the two-way axial displacement of the shaft and the housing. The allowable inclinability depends on the internal clearance of the bearing, bearing size, internal design and the force and moment acting on the bearing, and the maximum allowable inclination Angle should ensure that no excessive additional stress will be generated in the bearing.Features:
1 The contact angle can be 15, 25, 30 or 40 degrees.
2 There are 4 different preload includ light, medium, heavy and special preload.
3 he bearing's pairing way includ DB, DF, DT, PBC, QBC,TBT and universal paring.
4 Optional bearing's speed: High speed, high speed or super high speed
5 The bearing's highest working temperature is 120℃-150℃ depends on its material.
3 The optional precision level include P5 P4 P4A and P2.
7 The bearing's balls can be made of steel or ceramic.

Single row angular contact ball bearing are mainly used for machine tool spindle, high frequency motor, gas turbine, centrifuge, small automobile front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, welding machine, low noise type cooling tower, mechanical and electrical equipment, coating equipment, machine tool slot plate, arc welding machine
