Thrust Needle Roller Bearings consist of a precisely made cage and rollers. They have high rigidity and high load capacities and can be used in small spaces. Thrust Needle Roller Bearings incorporate needle rollers, while Thrust Roller Bearings incorporate cylindrical rollers.
Ball Bearings are a type of rolling-element bearing that uses balls to maintain the separation between the moving parts of the bearing. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads.
