Custom High Quality Single Needle Roller Bearing

Needle bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Although it has a small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so The radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest, especially suitable for support structures with limited radial installation dimensions.

We provide customers with a variety of needle roller bearing series products. Depending on the application, the bearing without inner ring or the needle roller and cage assembly can be selected. At this time, the journal surface and the shell hole surface matching the bearing are directly used as the inner surface of the bearing. 1. The outer rolling surface, in order to ensure the same load capacity and running performance as bearings with rings, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring.
