NSK & FAG (SCHAEFFLER) BALL BEARINGS

Statewide Bearings are the leading distributors of ball bearings in Australia. We offer a huge range of both ceramic and stainless-steel ball bearings for sale.

What are Ball Bearings?

Ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings, ball and cage assemblies.

These products are a simple design, robust in operation and easy to maintain.

Due to their relatively low frictional torque, deep groove ball bearings are suitable for high speeds. The angular adjustment facility of single-row ball bearings is limited, so bearing positions must be well aligned.

Ball bearings are manufactured with several various configurations which provide different features suitable for a wide range of applications, for example, angular contact or double row.

FAG (Schaeffler) and NSK both manufacture a comprehensive range of deep groove ball bearings that meet, if not exceed, ISO specifications. FAG (Schaeffler) & NSK offer a range of specific products with various features and benefits to offer a solution across most applications.

Ball type bearings can be broadly categorized into the following groups:

Single-row deep groove ball bearings

These are rigid and non-separable radial bearings. The balls run in deep grooves in both the inner and outer rings. This enables a good load capacity in both radial and axial directions.

Single-row angular contact ball bearings

These are also rigid and non-separable radial bearings. However, these are produced with several different contact angles which means they only accept thrust loads in one direction.

They must therefore be used in pairs where a bearing has to be adjusted against another to guide the shaft in the opposite direction.

These bearings are suitable for high-speed applications, accommodating both radial and thrust forces which can include combined loads and tilting movements.

Self-aligning ball bearings

These are non-separable double-row radial bearings. Both rows of balls rotate in parallel within a spherical outer ring. This feature allows for excellent misalignment which can be caused by machining and mounting errors.

These series are suitable for low to medium loads, including relatively low thrust force.

Thrust ball bearings

These are separable axial bearings that assist in simple mounting or dismounting. The bearing washers, cage and ball assemblies mean each may be individually mounted in location.

Thrust ball bearings accommodate a rather high axial load, but cannot be used while radial forces are present. They do not compensate for any misalignment.

It is recommended that you consult your local Statewide Bearings branch and engineering team to ensure you get the most appropriate bearing for your application.
