Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.

Features of Needle roller bearings and cage assemblies

1.Lowest cross section among rolling bearings
needle roller and cage assemblies are self-contained, ready to mount bearings. In applications where the shaft and housing bore can serve as raceways, the assemblies can be used to create bearing arrangements that require minimal radial space.
2.High load carrying capacity
Owing to their large number of rollers, needle roller and cage assemblies have a high load carrying capacity.
3.High stiffness
Because of their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.

Applications of Needle roller bearings and cage assemblies
Automotive transmissions, air-conditioner compressors, bulldozer blades, overhead traveling cranes, gearboxes, machine tool spindles, copying machines and so on.
Radial needle roller and cage assemblies can support high radial loads and allow high speeds. They combine the load carrying capacity advantages of full complement needle roller bearing arrangements with the speed advantages of a cage bearing and are easy to mount.
