Concrete Mixer Bearing

The design of double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings, but only occupies smaller axial space. Double row angular contact ball bearings can withstand radial loads and axial loads acting in both directions. They can limit the bidirectional axial displacement of the shaft or shell, with a contact angle of 30 degrees. It can provide a highly rigid bearing configuration and withstand overturning torque.

Double row angular contact ball bearings can withstand significant radial and axial combined loads and torque loads, limiting the axial displacement of both sides of the shaft. Mainly used in components that limit the bidirectional axial displacement of the shaft and casing

The tilting ability between the inner and outer rings of double row angular contact ball bearings is limited, and the allowable tilting angle depends on the internal clearance, bearing size, internal design, and the forces and moments acting on the bearing. The maximum allowable tilting angle should ensure that there is no excessive additional stress generated in the bearing.

If there is a tilt angle between the inner and outer rings of the bearing, it will affect the service life of the bearing, and at the same time cause a decrease in the operating accuracy of the bearing and an increase in operating noise. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, it should be noted that although the bearings can withstand bidirectional axial loads, if there is a ball gap on one side, attention should be paid not to let the main axial load pass through the groove edge on the side with the gap. When using bearings, attention should be paid to ensuring that the raceway on the side without the ball gap bears the main load.
