Needle beaing
Needle roller bearings are essentially cylindrical roller bearings except that their cylindrical rollers have a length 3 to 10 times their diameter (versus a length less than 3 times their diameter). Needle bearings are also essentially bearings that utilize small & cylindric rollers. Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. Even though they have a low cross section, needle roller bearings have a high radial load capacity and are exceptionally apt for bearing applications where radial space is limited.
There are numerous types available, and many have no inner rings. The drawn-cup type has a pressed steel outer ring and the precision (solid) type has a machined outer ring. There are also cage-and-roller assemblies without rings. Most bearings have pressed steel cages, but some are without cages.
Drawn cup needle roller bearings have a drawn outer shell serving as a raceway for the rollers and are installed with a press fit in the housing. They are ideal for many of the following applications: transmissions, transfer cases, engines, valve trains, steering and braking systems, axle supports, outboard engines, textile industry, power tools, copiers, fax machines, paper-moving equipment, and appliances.
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 | ||
