A single row angular contact ball bearing can only bear axial load in one direction. When the bearing bears radial load, additional axial force will be generated.Only the axial displacement of the shaft or housing in one direction can be limited.The contact Angle of angular contact ball bearing is 40°, which can bear large axial load.Angular contact ball bearing is a non - separation design with different shoulder heights on both sides of the inner and outer rings.To increase bearing capacity, one side of the shoulder is machined lower so that the bearing can be loaded into more steel balls.
Double row angular contact ball bearings can bear large radial load, axial composite load and torque load, and can limit the axial displacement of the shaft.The inclination ability between the inner ring and the outer ring of the double-row angular contact ball bearing is limited, which is mainly used to limit the axial displacement of the shaft and housing.Allowable inclination depends on the bearing's internal clearance, bearing size, internal design, and the force and torque applied to the bearing.If there is an inclination Angle between the inner and outer rings of the bearing, it will affect the service life of the bearing, reduce the running accuracy of the bearing and increase the running noise.Double row angular contact ball bearings are usually made of nylon cage or brass solid cage.When installing the double-row angular contact ball bearing, it should be noted that although the bearing can bear two-way axial load, if there is a gap on one side of the ball, it should be noted that the spindle load should not pass through the groove.When bearings are in use, care should be taken to make the side of the runway free from the ball gap to bear the main load.
Double ball bearings
If mounted in pairs, the outer ring of a pair of bearings is opposite, that is, wide end face and narrow end face.This avoids additional axial forces and limits the axial clearance of the shaft or housing in both directions.
Because the raceway of its inner ring and outer ring has relative displacement on the horizontal axis, it can bear both radial load and axial load - combined load (single row angular contact ball bearing can only bear one direction of axial load, so it is usually installed in pairs).
Cage material is brass, synthetic resin, etc., according to the bearing form, use conditions, etc.
Foreign bearing manufacturers have produced more angular contact ball bearings, in the imported equipment such as angular contact ball bearings 3204RS and other aspects of more domestic applications.
