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 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 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.

NSK manufactures a complete range of spherical roller bearings from 25mm to 1.5m bore diameter with the option of parallel or tapered bores (for use with NSK adapter or withdrawal sleeves). Other sizes may also be available on request.
Spherical roller bearings can support high radial loads and moderate axial loads in either direction. They are also suitable for applications involving moderate shock or impact loads.
The inner ring guides two rows of barrel-shaped rollers, with a single spherical outer ring raceway. As such, these bearing can accommodate a varying degree of misalignment depending on their size, but normally between 0.018 and 0.045 radian (1 to 2.5 degrees) with average loads.
Different cage materials are available for these bearings including steel, brass or polyamide depending on the requirements of the application. These bearings are also available with an oil groove and holes in the outer ring for re-lubrication purposes.
In addition, NSK can provide a range of specially designed spherical roller bearings for vibrating machinery applications.

Spherical roller bearings are inherently self-aligning and very robust. The two rows of rollers make the bearings able to carry heavy loads. Invented by SKF and refined over the years, the present SKF range of spherical roller bearings includes a wide range of sizes of several ISO Dimension Series and also includes special designs, for example, for vibrating screens and similar applications. More recently a range of sealed spherical roller bearings has been added to the assortment. Split spherical roller bearings are usually based on the standard bearings but can be customized as required.

SNR has conducted joint research plans with its steel suppliers, focusing on steel quality evolution; now, the company uses special alloys featuring the utmost cleanliness level. This new steel quality, generalised on our spherical roller bearings, provides higher performance and endurance than the other steel grades used so far.
Furthermore, the heat treatment which is especially applied to the SNR spherical roller bearings guarantees dimensional stability up to 200 °C. The quality of this treatment results in higher endurance and higher ultimate strength and wear resistance of the bearings, allowing them to sustain the most aggressive operating conditions.
Therefore, the combined evolution of the materials and technologies gave rise to an 18 % increase in the dynamic load capacity of the SNR spherical roller bearings, as well as a 75 % service life extension, making our bearings the best performers on the market, while remaining within the same ISO standardisation envelope and in compliance with the ISO standard for basic dynamic load calculation.
Application examples: Rolling mill cages, large reduction gears, large industrial fans, printing press cylinders, quarry machines…

Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.
The symmetrical barrel rollers freely align themselves to the concave outer ring raceway. As a result, shaft deflections and mislignments of the bearing seats are compensated.
X-life
Many sizes of spherical roller bearings are supplied in X-life design. These bearings do not have a central rib on the inner ring so longer barrel rollers can be fitted; improved kinematics, optimised surfaces and even higher performance materials are possible. As a result, the bearings show a significant increase in the basic dynamic load rating and, under the same operating conditions, in the basic rating life. In certain applications, a smaller design of bearing arrangement can therefore be used if necessary. |

RKB offers spherical roller bearings customized for specific applications as bearings with split outer ring (suffix WOR) or with increased width dimension and larger rollers for milling applications (project designation SRB) or for the support of the rolls of cold rolling Pilger mills for tubes.
Such bearings are provided with annular groove and lubrication holes in the outer and/or in the inner ring (suffix W33, W33X, W20, W26).
They are manufactured in different constructive internal design versions (e.g. CA, MB, MF, CC).
The bearings of normal design are fitted with machined brass or steel cage guided on the rollers or on the inner ring or outer ring raceway.
The radial clearance can be normal, larger than normal (suffix C3, C4, C5) or smaller than normal (suffix C2) in accordance with ISO 5753.
Some of RKB spherical roller bearings are also manufactured in the sealed version reinforced with steel sheet and made of an oil and wear resistant rubber.
In order to locate the spherical roller bearings with the tapered bore onto a cylindrical seating, the adapter (designation H) or withdrawal (designation AH) sleeves are the most commonly used components with large shafts with h9 and h10 tolerance.
For large sized bearings, both adapter and withdrawal sleeves are provided with oil grooves and oil duct at the threaded side to enable the oil injection method to be used for easy mounting and dismounting (designation OH and AOH). |
