Double row angular contact ball bearings can withstand larger radial load and axial joint load and torque load, limit the axial displacement of the two aspects. Mainly used for limiting the axial displacement of the shaft and the shell.
Double row angular contact ball bearing inner and outer ring of the tilt between the limited, allowing the tilt angle depends on the internal clearance of the bearing, bearing size, internal design and role in bearing the force and torque, and the maximum allowable inclination angle should ensure that the bearing will not produce high additional stress.
Precision Matching of The Product:
UTE precision angular contact ball bearings can be supplied by assemble sets with two, three, four or five bearings to form a complete bearing group. The elements of bearing group are produced by matching requirement, so that the bearings can get the predetermined preload and rigidity after installation. The inner and outer diameter and angle of the same bearing group shall be controlled within the allowable tolerance. For bearings with special requirement, the tolerance will be even smaller.
The difficulty of multiple bearing matching is how to control the accumulative tolerances. UTE has solved this problem by using precision matching technology.
