What Does SKF 7313 BEGAM Mean?

7313 - Bearing Series and Size

The designation 7313 identifies a single row angular contact ball bearing belonging to the 73 dimensional series.

Its principal dimensions are:

• Bore diameter: 65 mm.

• Outside diameter: 140 mm.

• Bearing width: 33 mm.

The 73 series comprises angular contact ball bearings designed to accommodate combined radial and axial loads.

B - 40-Degree Contact Angle

The suffix B identifies a bearing with a nominal contact angle of 40 degrees.

The contact angle describes the direction of load transmission between the balls and raceways.

A 40-degree contact angle enables the bearing to accommodate substantial axial loads in one direction together with radial loads.

This characteristic is particularly important when selecting bearings for combined loading conditions.

E - Optimized Internal Design

The letter E identifies an optimized internal bearing design.

This design influences the internal geometry and the load-carrying characteristics of the bearing.

SKF 7313 BEGAM should not automatically be considered equivalent to other 7313 variants with different internal designs.

GA - Universally Matchable Bearing for Light Preload

The suffix GA identifies a universally matchable bearing designed to provide light preload when correctly paired with another compatible bearing.

Universally matchable angular contact ball bearings can be arranged in:

• Back-to-back configurations.

• Face-to-face configurations.

• Tandem configurations.

The resulting bearing arrangement characteristics depend on the selected configuration and matching requirements.

GA does not indicate C3 radial internal clearance.

M - Machined Brass Cage

The suffix M identifies a machined brass cage.

In SKF 7313 BEGAM, the cage is guided by the rolling elements.

The cage maintains the correct spacing between the balls and supports their guidance during operation.

This construction differs from polyamide and pressed steel cages used in other bearing variants.

Construction of SKF 7313 BEGAM

Inner and Outer Rings

The bearing incorporates one-piece inner and outer rings with raceways displaced relative to each other in the axial direction.

This geometry allows the bearing to accommodate combined radial and axial loading.

Steel Balls

The rolling elements are steel balls operating between the inner and outer ring raceways.

Loads are transmitted through rolling contact at a nominal contact angle of 40 degrees.

Machined Brass Cage

The machined brass cage separates the balls and maintains their circumferential spacing.

Its construction differs from polymer and pressed steel cage designs.

The cage material and guidance arrangement must be considered when evaluating the operating conditions.

Open Bearing Construction

SKF 7313 BEGAM is an open bearing without integrated seals or shields.

The bearing arrangement must provide appropriate lubrication and protection against contamination.

Radial and Axial Load Capacity

Radial Loads

SKF 7313 BEGAM accommodates loads acting perpendicular to the shaft axis.

Its basic dynamic load rating C is 116 kN, while its basic static load rating C0 is 86.5 kN.

These ratings are used in bearing life calculations and load assessments.

They must not be interpreted as universally permissible operating loads under all conditions.

Axial Loads

A single row angular contact ball bearing accommodates axial loads in one direction.

To support axial loads acting in both directions, an appropriately arranged bearing pair or another suitable bearing arrangement is generally required.

Combined Loads

SKF 7313 BEGAM can accommodate radial and axial loads simultaneously.

Its 40-degree contact angle is an important parameter when calculating load distribution and selecting the bearing arrangement.

Universally Matchable GA Design

The GA execution is one of the defining characteristics of SKF 7313 BEGAM.

It allows compatible bearings to be matched in different configurations while providing the specified light preload under the appropriate mounting conditions.

Back-to-Back Arrangement

In a back-to-back arrangement, the bearings are positioned with their contact lines diverging outward.

This configuration can provide relatively high moment stiffness and resistance to tilting moments.

It is often selected where shaft support rigidity is important.

Face-to-Face Arrangement

In a face-to-face arrangement, the bearing contact lines converge inward.

This configuration accommodates axial loads in both directions but has different stiffness and misalignment characteristics compared with a back-to-back arrangement.

Tandem Arrangement

In a tandem arrangement, the bearings are oriented in the same direction.

This configuration is used when increased axial load-carrying capacity is required in one direction.

The selection of a bearing configuration requires engineering calculations and consideration of the complete mechanical assembly.

SKF 7313 BEGAM vs Other Bearing Variants

Identical principal dimensions of 65x140x33 mm do not guarantee identical operating characteristics or interchangeability.

7313 BEGAM vs 7313 BECBM

SKF 7313 BEGAM is designed for universal matching with light preload.

SKF 7313 BECBM belongs to a matching execution associated with the CB axial clearance class.

This difference is important when selecting or replacing bearings operating in matched pairs.

7313 BEGAM vs 7313 BEGBM

Both versions incorporate machined brass cages and are designed for universal matching.

However, GA and GB identify different preload classes.

The variants should not be interchanged without evaluating the required stiffness, operating loads and temperature conditions.

7313 BEGAM vs 7313 BEP

Both are single row angular contact ball bearings belonging to the same dimensional series.

However, the suffixes identify different internal and cage executions.

Matching dimensions alone are insufficient to establish technical equivalence.

Typical Applications of Single Row Angular Contact Ball Bearings

Angular contact ball bearings are used in mechanical assemblies where radial and axial loads act simultaneously.

Typical application categories include:

• Industrial machine shafts.

• Pump assemblies.

• Mechanical drive systems.

• Rotating machinery.

• Matched bearing arrangements.

• Mechanical systems requiring defined axial stiffness.

These are general applications based on angular contact ball bearing construction.

They do not establish confirmed installation of SKF 7313 BEGAM in any specific machine model.

Industrial Shaft Support

Angular contact ball bearings can provide radial support while accommodating axial loading in a defined direction.

Correct arrangement depends on the direction and magnitude of the applied loads.

Pump Assemblies

Angular contact ball bearings are used in suitable pump arrangements where rotating shafts experience combined radial and axial loading.

Bearing selection must account for speed, lubrication and thermal operating conditions.

Matched Bearing Arrangements

Universally matchable angular contact ball bearings can be used in pairs to achieve specific axial load-carrying and stiffness characteristics.

The GA execution must be considered when selecting the matching configuration.
