NSK Ball Bearings

NSK Deep Groove Ball Bearings

NSK manufactures a full range of Deep Groove Ball Bearings (DGBB). These include single row deep groove ball bearings, extra small ball bearings and miniature ball bearings, maxi ball bearings and magnetic bearings. These versatile bearings are the most common types and serve a wide range of industries.
In addition to radial loads, these bearings can also carry axial loads in both directions and offer low frictional torque and high speed components, ideal for applications requiring low noise and vibration.

NSK Angular Contact Ball Bearings

NSK’s comprehensive range of angular contact ball bearings is designed to meet the ever-changing requirements of equipment manufacturers. The main types include: Single-Row Angular Contact Ball Bearings; Matched Angular Contact Ball Bearings; Double-Row Angular contact ball bearings have a contact angle that allows them to carry radial loads while simultaneously carrying significant axial loads in one direction. These bearings are usually used in pairs or multi bearing sets

NSK Self-Aligning Ball Bearings

NSK Self-aligning ball bearings are recommended for applications where the shaft and housing are difficult to align or where the shaft may be bent, such as drive shafts. Self-aligning ball bearings have a spherical raceway on the outer ring whose centre of curvature coincides with the centre of curvature of the bearing, allowing the axis of the inner ring, ball and cage to rotate freely around the centre of the bearing.

NSK Thrust Ball Bearings

Thrust ball bearings are designed to carry axial (poussée) loads at high speeds, but they cannot carry any radial loads. These bearings feature bearing washers with raceway grooves in which the balls move. Thrust ball bearings are mainly divided into Double-Direction Thrust Ball Bearings and Single-Direction Thrust Ball Bearings.

NSK N Series Thin-Section Ball Bearings

Extremely thin-section ball bearings contribute to equipment miniaturization, perte de poids, and low torque for robots, construction equipment, and industrial machinery.

With lower frictional torque and less torque variation, N series bearings improve torque transmission and provide smooth rotation. These high-precision bearings also support high speeds.

NSK Roller Bearings

NSK Cylindrical Roller Bearings

Cylindrical roller bearings (CRB) have cylindrical rollers in linear contact with the raceways and are simple in construction. They provide high load capacity under predominantly radial loads. The low friction between the rollers and the retaining edges makes these bearings suitable for high speeds.
Cylindrical roller bearing types：

NE PAS, N, NNU, NN: suitable as free end bearings.
New Jersey, NF: can carry limited axial loads in one direction.
NH, NUP: suitable as fixed end bearings. The NH type consists of a CRB type NJ and an L-shaped thrust ring type HJ.

NSK Tapered Roller Bearings

Tapered roller bearings are designed so that the imaginary cone apexes formed by the inner and outer ring raceways and rollers converge on a point on the bearing axis. The trapezoidal tapered rollers used as rolling elements are guided by a large retaining edge on the inner ring.
Tapered roller bearings are divided into normal, medium and large angle types according to their contact angle. In addition to the two-row type, there are also four-row tapered roller bearings. Pressed cages are usually used, but larger bearings may use pin cages.

NSK Spherical Roller Bearings

Spherical roller bearings are available in types EA, C, CD and CA and are designed for high load capacities. Types EA, C and CD use stamped steel cages, while CA uses machined brass cages. All EA types are high performance standard NSKHPS series bearings.
Spherical roller bearings with the “E4” suffix have oil grooves and holes in the outer ring. Due to the limited depth of the oil grooves in these bearings, we recommend that oil grooves are also used in the housing bores.

NSK Thrust Roller Bearings

NSK’s axial roller bearings are only axially loaded, but are suitable for heavy loads and provide high axial rigidity. The main types of thrust roller bearings are: Paliers de butée à rouleaux cylindriques; Tapered Roller Thrust Bearings and Spherical Roller Thrust Bearings.

NSK Needle Roller Bearings

Needle roller bearings (sometimes called “roulements à aiguilles”) use long, narrow cylindrical rollers, sometimes exceeding the JIS/ISO size range. According to the direction of the load they support, they are divided into thrust bearings and radial bearings. Radial types include stamped cup and solid types, as well as application specific rollers (cam and roller follower). Thrust needle roller and thrust roller bearings handle the demands of axial loads.

NSK Bearing Units

NSK Ball Bearing Units

NSK ball bearing units combine bearings, bearing housings and sealing components into a standardized form and are used in key parts of equipment. The use of ball bearing units simplifies the surrounding structure, making installation and maintenance more efficient. Because they provide proper alignment, bearing units help prevent bending moment loads caused by installation errors. Bearing units can also be easily mounted on machine bases or side walls, so they can be used in a variety of places, including frame structures.

NSK bearing manufacturing process: The bearings we produce will be produced in the factory using molds first, and then will be inspected by professional quality inspectors to screen out unqualified products. It is then packed by workers and placed in our warehouse, waiting to be delivered to the people who need it.
