65BNR10STYNSUELP4 angular contact ball bearings
Single row angular contact ball bearings can only withstand axial loads in one direction, which will cause additional axial forces when subjected to radial loads. And can 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 significant axial loads. Angular contact ball bearings are non separable designs, with varying shoulder heights on both sides of the inner and outer rings. In order to improve the bearing's load capacity, the shoulder on one side will be machined lower, allowing the bearing to accommodate more steel balls.
Double row angular contact ball bearings can withstand large radial and axial combined loads and torque loads, mainly radial loads, limiting both axial displacement of the shaft. The tilting ability between the inner and outer rings of a double row angular contact ball bearing, which is mainly used to limit the bidirectional axial displacement of the shaft and housing, is limited. The allowable tilting angle depends on the internal clearance of the bearing, bearing size, internal design, and the forces and moments acting on the bearing. The maximum allowable tilting angle should ensure that excessive additional stresses do not occur in 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, and at the same time, cause a decrease in the operating accuracy of the bearing, and increase the operating noise. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing a double row angular contact ball bearing, it should be noted that although the bearing can withstand bidirectional axial loads, if there is a ball mounting gap on one side, it should be noted not to allow the main axial load to pass through the groove on the notched side. When using bearings, attention should be paid to making the raceway on the side without the ball mounting notch bear the main load.
