Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition, to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high-speed applications.

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

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.

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.

Spherical Roller bearings are designed for carrying high loads along with RPM & angular Misalignment as well. They can carry high load capacity, features low torque, and has a high-strength cage.

An oil groove and holes are provided in the outer ring to supply lubricant for ease of operation.

In bearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.

The outer and inner rings of all types are separable.

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.

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.

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.

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.

Features

1. This line up of bearing includes a basic series that meets ISO standards, and a specified series targeting machine tools.2. A series of sealed angular contact ball bearings with pre-packed grease is available.3. The Robust series of high performance bearings include, a wide line up of bearings, ranging from highly rigid types to ultrahigh-speed types.

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

Features

1. The highly rigid series for machine tool applications has been designed specifically to provide large axial rigidity and precise rotation with lower starting torque.2. The highly rigid series is available with a lubricant seal for machine tool applications.3. The high load capacity series for electric injection moulding machines offers enhanced service life through the use of optimally designed ball diameter and contact angle for a higher load rating.
