Needle roller bearings are equipped with thin and long rollers (the length of the rollers is 3 to 10 times the diameter, and the diameter is generally not more than 5 mm). Therefore, the radial structure is compact. It has the smallest diameter and is especially suitable for supporting structures with limited radial installation dimensions.
Needle roller bearings are used according to different applications. The machining accuracy and surface quality should be combined with bearing rings and applications. Needle roller bearings are bearing units that combine radial needle roller bearings and thrust bearing components.
