INA bearings selected for six aspects

INA bearing type selection is determined by acting on the bearing load direction, and choose the appropriate interface combination depends mainly on the role of the load. Here introduce a few kinds of load way: 1, the radial load when the load is purely radial load or primarily radial load, should choose radial spherical bearing. In addition to the radial load, these INA bearings can absorb a certain amount of axial load. 2, axial load when the load is a major is pure axial load or axial load, should choose spherical thrust bearing. In addition to the axial load, these INA bearings can bear radial load. 3, joint load when the load from nearly equal to the size of the radial and axial force component composition, should choose angular contact ball bearing. This kind of bearings can only carry axial load from one direction, generally depends on the second INA bearing adjustment, bear the axial load from the opposite direction. 4, the direction of directional load such as load constant, the relative motion of the contact surface under the dynamic condition have larger, then maintenance-free bearing is the best choice. But, as a slight swing motion is rare, Quasi static condition) , or, in unusual swing motion of the bearings can bear a heavy load and impact load happens, should use steel to steel bearings. 5, alternating direction load such as load changes direction, using steel to steel INA bearing is more suitable. Maintenance-free bearing has only a limited scope of 6, orientation and direction of alternating load in some applications, the load in a direction role after a period of time, once again become a cyclic load, the applications need to use special INA bearings.
