RBC produces an extensive heavy duty needle roller bearing product line from 1 inch outer ring diameter to 12 ¼ inch outer ring diameter. RBC has the capability to manufacture special designs up to a 39 inch outer diameter.
The RBC SJ series of Pitchlign® heavy duty needle roller bearings are supplied in standard envelopes in both sealed and unsealed configurations. There are eight possible seal configurations. The seals can include double or single seal with the seal lip turned inward or outward. The seal can be mounted in the radius end of the ring or the chamfered end of the ring for optimum mounting variations.
RBC%u2019s patented TJ TandemRoller® heavy duty needle roller bearings increase the capacity of the standard Pitchlign® SJ series from 10% to 40% while maintaining the standard SJ envelope dimensions. The TJ design gives the heavy duty needle roller bearing 37% to 200% greater life over a standard single pocket bearing. These bearings are also available in sealed and unsealed configurations.

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 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.

McGill has a broad variety of heavy-duty needle bearings with two series to choose from: CAGEROL & GUIDEROL Bearings.
CAGEROL Cage Type Needle Bearings are designed to accommodate higher speeds and some misalignment. Crowned rollers help increase the load rating of the bearings and steel cages provide accurate roller guidance.
GUIDEROL Heavy-Duty Needle Bearings with center guided rollers utilize a full complement of rollers extending virtually the complete width of the outer race for maximum support. They are designed to provide higher static load capacities and more radial rigidity in applications involving gears, rollers, sheaves, levers, etc.

Needle roller bearings have a cylindrical needle-type roller with a comparatively small diameter, where the length is greater than the diameter. Needle roller bearings have small cross-sectional height, and compared with other types of bearings, feature high load capacity and rigidity compared to the space taken by the bearing. Another feature is the low inertial force, which is appropriate for oscillating motion. Using these bearings, it is possible to make mechanical equipment smaller and lighter in weight. Also, it is easy to replace a sliding bearing with a Needle roller bearing.

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 ball bearings.
Needle roller/cylindrical roller thrust bearings.
- Needle roller thrust bearings (separate section).

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).

Axial needle roller bearings
Axial needle roller bearings are units comprising axial needle roller and cage assemblies and axial bearing washers with a centring spigot. They can be combined with drawn cup needle roller bearings and needle roller bearings. The axial running surface for the needle roller and cage assembly must be hardened and ground.
Axial needle roller and cage assemblies
Axial needle roller and cage assemblies comprise plastic or metal axial cages with integrated needle rollers and have a very small axial section height. They can support high axial forces in one direction. Radial loads must be supported by separate means. Axial needle roller and cage assemblies require hardened and ground axial running surfaces for use as raceways.

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.
