PRODUCT FEATURES
The basic structure of the inner ring bearing is the same as that of the NU type cylindrical roller bearing, but due to the use of the needle roller, the volume can be reduced, and the large radial load can be withstood without the inner ring bearing. The mounting surface of the shaft with appropriate precision and hardness should be used as the mounting surface. The raceway surface is used.

Feature | Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3 to 10 times the diameter and the diameter is generally not more than 5 mm), so the radial structure is compact, and the inner diameter and load capacity are the same as those of other types of bearings. The smallest diameter, especially suitable for support structures with limited radial mounting dimensions | ||
Needle roller bearings should be combined with bearing rings and applications depending on the application. A needle bearing is a bearing unit that combines a radial needle bearing and a thrust bearing component | |||
Applications | Automotive engines, transmissions, pumps, excavator track wheels, hoists, bridge cranes, compressors | ||
