Needle rolling manufacturer answers the stress relationship between roller and cage for you

The pull rod pin shaft is suitable for bearing axial load, unilateral radial load and axial and radial collaborative load. The radial load capacity of the deep groove ball bearing lies in the contact angle, that is, the angle of view of the outer dovetail guide rail. The larger the contact angle is, the greater the radial load capacity is. Generally, deep groove ball bearings are not allowed to have visual angle deviation, but the surface of roller bearings and dovetail guide rails can be allowed to have 2 ′～ 4 ′ visual angle deviation after experiencing a unique design scheme.

The single row deep groove ball bearing of automobile pin shaft can bear a radial load in one direction and limit the radial offset in one direction of shaft relative bearing with seat. Even under the effect of pure axial load, there will be additional radial force inside the deep groove ball bearing. At this time, there must be an equal opposite mutual force to balance with it.

Generally, two deep groove ball bearings of the same structure are selected from two support plates for zero distance or back-to-back relative installation. In order to ensure the excellent operation of the pin shaft diameter, deep groove ball bearings, like other ball bearings and roller bearings, must release a certain amount of load, especially for high speed, high instantaneous speed, or under the standard of frequent change of load direction.

Because of this working condition standard, the inertia moment of roller bearing and cage as well as the friction in the lubricating fluid will have a negative impact on the rolling bearing's overturning and rotation precision, and there will be a driving healthy movement in the middle of roller bearing and dovetail guide rail which will cause harm to the rolling bearing.

Generally speaking, the net weight of the rolling bearing support plate plus the load borne by the rolling bearing has already exceeded the required load. If the load is not exceeded, the additional axial load must be applied to the rolling bearing, such as releasing the radial moment to the rolling bearing to consider the load provisions.
