Axial load force and service life of metric rod end bearings

- Dec 17, 2018-

The radial dynamic load rating of the metric rod end bearing in use, and the radial load of the working surface dynamic stress in the joint bearing to the maximum allowable stress. The axial load of the working surface dynamic stress in the joint bearing reaches the maximum allowable stress. When it is used, its life is mainly the total number of times the joint bearing swings when the friction coefficient of the joint bearing reaches the specified limit value or the joint bearing wear exceeds the specified limit value.

The radial equivalent dynamic load of the metric rod end bearing, under the action of the load, the working surface contact stress in the joint bearing is equivalent to the actual load, and is mainly used for the radial joint bearing, the angular contact joint bearing, The rod end joint bearing is used to calculate the service life of the joint bearing when bearing radial load and axial load. In general, it is recommended not to exceed 30% of the radial load for the axial load of the radial and angular contact joint bearings. The axial load of the rod end joint bearing is recommended not to exceed 20% of the radial load.

The constant axial load of the metric rod end bearing, under the action of the load, the contact stress of the working surface in the joint bearing is equivalent to the actual load. It is used to calculate the service life of joint bearings when the thrust joint bearing is subjected to radial load and axial load. In general, the radial load on thrust joint bearings is recommended not to exceed 50% of the axial load.
