The design of SKF double row angular contact ball bearings corresponds to two single row angular contact ball bearings arranged back-to-back.

SKF single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

RHP was an amalgamation in 1969 of the three major British bearing manufacturers, dating back as far as 1898. The three companies were Ransome & Marles (1917), Hoffmann Manufacturing (1898), and the Pollard Ball & Roller Bearing Company (1933). The combined company, Ransome Hoffmann Pollard (RHP), became a highly respected brand across the globe in the industrial and aerospace industries, and even today remains a world-leading brand in Super Precision Bearings. The sales & engineering functions of NSK and RHP have been merged, and the RHP manufacturing facilities brought under the guiding influence of NSK’s stringent manufacturing principles. The RHP brand stands for the principles of NSK's manufacturing and engineering excellence, matching roller bearings made in Europe to our customers' exacting specifications.

NSK offers a wide lineup of precision angular contact ball bearings where customers to choose the optimum specification of bearing according to the needs of their application. NSK precision angular contact ball bearings provide the perfect solution for applications requiring high runout accuracy of rotating machine parts, such as the machine tool main spindles, or the application of faster rotating speeds.

Highly precise angular contact thrust ball bearings for precision ball screws have been designed specifically for each application. Lineup includes both a highly rigid series and high-capacity series.

NSK Spherical Roller Bearings are designed for high load capacity. EA, C and CD have pressed steel cages where as CA has machined brass cages. EA cage specially has high load capacity, low torque and has high strength cage. An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4.

The cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds. There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).

Bearings of this type use conical rollers guided by a back-face rib on the cone. These bearings are capable of taking high radial loads and axial loads in one direction. In the HR series, the rollers are increased in both size and number giving it an even higher load capacity. They are generally mounted in pairs in a manner similar to single-row angular contact ball bearings. In this case, the proper internal clearance can be obtained by adjusting the axial distance between the cones or cups of the two opposed bearings.

Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads.

This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center.

NSK manufactures a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.
