Needle roller bearings with thin and long roller (roller length of the diameter of 3 to 10 times the diameter is generally not greater than 5mm), so the radial structure is compact, easy to operate, Its inner diameter and load capacity and other types of bearings the same, the smallest diameter, especially for radial mounting size of the limited support structure. Needle roller bearings according to the use of different occasions, machining accuracy and surface quality should be used with the bearing ring, the combination. Needle roller bearings are radial bearings and thrust bearing components to the heart of the combination of the bearing unit.
