Needle roller bearings with three-point contact ball bearings withstand heavy radial loads and bidirectional axial loads at the same time during high-speed rotation.
Noninterchangeable inner rings are separated at the center of the ball raceway surface, and must be firmly tightened against shaft in the axial direction.
Axial clearance is 0.1-0.3 mm.
When the axial load exceeds 25% of the radial load, the radial load will be induced onto the angular contact ball bearing and the bearing life will be affected. Therefore, the relationship between the two loads must be carefully considered.
