NSK supply needle roller bearings through a joint venture of over forty years between NSK Ltd. and The Torrington Company (NSK-TORRINGTON).
Needle roller bearings contain slender rollers with a length of 3 to 10 times their diameter. The ratio of the bearing outside diameter to the inscribed circle diameter is small and, as a result, they have a high radial load capacity.
NSK-TORRINGTON can supply a full range of needle roller bearings including drawn-cup radial bearings with a pressed steel outer ring or solid radial bearings with a machined outer ring. The range also includes cam followers, roller followers, needle bearings for airframes and thrust needle bearings.
To prevent the ingress of contamination, NSK-TORRINGTON needle roller bearings can also be supplied with contact seals, non-contact labyrinth seals or flingers.

Needle roller and cage assemblies are single or double row units comprising cages and needle rollers.
Since their radial section is no greater than the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with a very small radial design envelope to be achieved. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted.
If the raceways are produced to high geometrical accuracy, bearing arrangements with high runout accuracy can be achieved.
The radial internal clearance can be influenced by the needle roller sort and by the shaft and housing tolerance.
Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.

Needle roller bearings are roller bearings with slender cylindrical rollers, they have the highest load capacity for a given radial space of all rolling-element bearings. This makes these bearings ideal for applications where radial space is limited but high radial load carrying capacity is required. Needle roller bearings are also suitable for applications with high rotational speed but cannot accommodate axial loads.
All needle bearings are variations of two basic designs. The first needle bearing design; full complement, has a full complement of needles and contains no retainer. The second needle bearing design; caged needle contains a retainer or cage for roller guidance and spacing. Caged needle bearings have smaller roller complements and lower load capacities than full-complement bearings.
Needle bearings have the advantage of a higher speed capacity; retainers prevent high-velocity rubbing between adjacent needles and provide more effective roller guidance
(Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty needle bearings never require re-lubrication, but high loads or speeds demand it).

Needle roller bearings are small in sectional height, therefore useful in making machinery smaller and lighter. This type of bearing is used in a wide range of machinery, such as automobiles, motor cycles, electric machines, machine tools, aerospace and office equipment.
Needle roller bearings are compact, highly rigid and superior in load carrying performance, compared with other types of bearings. Excellent for carrying oscillating loads; contains many small diameter rollers.
Widely employed in stud type and yoke type track rollers used as guide rollers in cam mechanisms or linear motion units.
Also used in miniature one-way clutches in the clutch mechanisms of office equipment, such as copying machines.

Needle roller bearings are roller bearings with cylindrical rollers which are thin and long in relation to their diameter. They are referred to as needle rollers. In spite of their low cross section the bearings have a high load carrying capacity and are thus extremely suitable for bearing arrangements where radial space is limited.
The SKF range of needle roller bearings is extensive and, in addition to customized designs, it comprises the following types:
- Needle roller and cage assemblies
- Drawn cup needle roller bearings with open ends and with closed end.
- Needle roller bearings with and without flanges with and without inner ring
- Sealed needle roller bearings with and without inner ring.
- Alignment needle roller bearings with and without inner ring
- Inner rings for needle roller bearings.
- Combined needle roller bearings (separate section). Needle roller/angular contact ball bearings.

Needle roller thrust bearings can support heavy axial loads, are insensitive to shock loads and provide stiff bearing arrangements which require a minimum of axial space. They are single direction bearings and can only accommodate axial loads acting in one direction. Particularly compact bearing arrangements can be made, taking up no more space than a conventional thrust washer, if the faces of adjacent machine components can serve as raceways for a needle roller and cage thrust assembly. For applications where adjacent components cannot serve as raceways, the assemblies can also be combined with washers of various designs.

The backing bearings based on cylindrical roller bearings have two or three rows of rollers and are available as full complement bearings (without cage) or as caged bearings, with or without integral flanges or flange rings. The advantage of the bearings without flanges lies in their particularly simple geometrical form and their very high radial load carrying capacity.
Cylindrical roller backing bearings without flanges or flange rings cannot accommodate any axial load. It is therefore necessary to position thrust washers of bronze or plastic between the side faces of the outer ring and the support saddles.
Thrust washers are not required with backing bearings with flanges (or flange rings) as the design of these bearings enables them to accommodate simultaneously acting radial and axial forces.
On each backing shaft of a cluster mill, several bearings are installed side by side. With their outside diameter surface in direct contact with the intermediate rolls, these bearings rotate while carrying components of rolling force. Therefore, the outer rings of these bearings are required to have adequate rigidity and fatigue strength, and should be finished with high precision.
