[0002] Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. These rollers are called needle rollers. Despite their small cross-section, the bearings have a high load-bearing capacity, resulting in a compact radial structure. When the bore size and load capacity are the same as other bearing types, the outer diameter is minimized, making them particularly suitable for support structures with restricted radial mounting dimensions.

[0003] At present, the assembly of needle roller bearings mainly utilizes multiple clamping grooves opened on a rotating disk for loading and unloading. However, the cavity size of the clamping groove on the current rotating disk is fixed, and the size of the space cannot be changed according to bearings of different sizes to adapt to the bearings and facilitate the stability of the bearings. When the size of the loaded bearing changes, it is necessary to remove the original rotating disk and install a rotating disk adapted to the bearing size. Therefore, the applicability of the turntable needle roller loading device for loading is reduced, and the complexity of adjusting the space of the clamping groove of the rotating disk is increased.
