Deep Groove Ball Bearings
NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.
Angular Contact Ball Bearings
The NSK range of angular contact ball bearings has been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads. Furthermore, since an axial component is generated when a radial load is applied, these bearings are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets. NSK offers one of the most comprehensive ranges of angular contact ball bearings available.
1, High Quality Steel - Ultra clean steel to extend bearing life by up to 80%.
2, Advanced Grease Technology - NSK lubricants that can extend grease life and performance.
3, High Grade Balls - Quiet and smooth operation even at high speed.
4, Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life.
5, Contact Angle - Offered in 15, 25, 30 and 40 degree angles.
6, Cages - Available in a range of Polyamide, steel and brass cage assemblies.
Self-Aligning Ball Bearings
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. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.
However, depending on the surrounding structure, such an angle may not be possible.
Thrust Ball 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. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used The cages in Double- Direction Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series.
1, Available in two designs: single direction and double direction.
2, To accommodate initial misalignments in an assembly both designs are available with spherical aligning seats or aligning seat washers.
3, High quality steel-ultra clean steel to extend bearing life by up to 80%.
4, Advanced Grease Technology - NSK lubricants that can extend grease life and performance.
5, High Grade Balls - Quiet and smooth operation even at high speed.
6, Optional seating rings take initial misalignment.
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. Since they are separable, the cone assemblies and cups can be mounted independently.
Depending upon the contact angle, tapered roller bearings are divided into three types; normal angle, medium angle, and steep angle.
Double-row and four-row tapered roller bearings are also available. Pressed steel cages are generally used.
Available with cylindrical or spherical rollers, NSK's thrust roller bearings sustain only axial loads, but they are suitable for heavy loads and have high axial rigidity. Spherical thrust roller bearings contain convex rollers and have a self- aligning capability and are free of any influence of mounting error or shaft deflection. Standard cages are machined brass, where the E-type offers a pressed cage for high load capacity.
Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and roller followers. Thrust bearings include thrust needle bearings.
