Characteristics and application of angular contact ball bearings

What is angular contact ball bearing

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

The inner and outer rings of angular contact ball bearings are provided with raceways, and the inner and outer rings can make phase displacement along the axial direction of the bearing. This kind of bearing is especially suitable for bearing compound load, namely radial and axial action of the negative load. The axial load bearing capacity of angular contact ball bearing increases with the increase of contact Angle α. The contact Angle is the Angle between the contact points of the ball and the raceway in the radial plane and the vertical line of the bearing axis.

Angular contact ball bearing

Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused. 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 large axial loads. Angular contact ball bearings are of a non-separable design with different shoulders on both sides of the inner and outer rings. In order to increase the bearing load capacity, one shoulder is machined lower so that the bearing can hold more steel balls

Characteristics and application of angular contact ball bearings

Double row angular contact spherical axis

Double row angular contact ball bearings can withstand the combined radial and axial loads and torque loads, which are mainly radial loads, and limit the axial displacement of the two aspects of the shaft. Is mainly used for two-way axial displacement limit shaft and the shell parts of double row angular contact ball bearing can be skewed between inner and outer ring is limited, allowing Angle depends on the bearing internal clearance, bearing on the size, in the role of interior design, and the bearing force and moment, and the maximum allowable slope Angle should guarantee won't produce high additional stress in the bearing.

If there is an inclination Angle between the inner and outer rings of the bearing, the life of the bearing will be affected, and the running accuracy of the bearing will decrease, and the running noise will increase. Double row angular contact ball bearings generally use nylon cage or brass solid cage. When installing double row angular contact ball bearings, it should be noted that although the bearings can withstand two-way axial load, if there is a ball gap on one side, it should be noted not to let the main axial load pass through the notch on one side. In the use of bearings, attention should be paid to the side of the raceway without ball loading gap to bear the main load.

Application range of angular contact ball bearings

Single row angular contact ball bearing: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, welding machine, low noise cooling tower, mechanical and electrical equipment, painting equipment, machine tool groove plate, arc welding machine
