NSK Bearing

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.

Features

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.

Features

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.

N Series Thin-Section Ball Bearings Metric and Inch Designs

Extremely thin-section ball bearings and roller bearings contributing to downsizing, weight saving, and reduction of torque loss of robots, construction equipments, and industrial machinery.

Features

1. Low frictional and irregular torque ensure highly efficient power transmission and smooth rotating performance.
2. The high accuracy of the bearings enables excellent high-speed performance.
