What Does SKF 7320 BEGAM Mean?

7320 - Bearing Series and Size

The designation 7320 identifies a single row angular contact ball bearing belonging to the 73 series.

Its principal dimensions are:

• Bore diameter: 100 mm.

• Outside diameter: 215 mm.

• Bearing width: 47 mm.

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

B - 40-Degree Contact Angle

The letter B indicates a nominal contact angle of 40 degrees.

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

A 40-degree contact angle enables the bearing to accommodate substantial axial loads in one direction while simultaneously supporting radial loads.

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

E - Optimized Internal Design

The letter E identifies an optimized internal bearing design.

The geometry of the raceways and rolling elements influences load-carrying capability and operating characteristics.

The BE execution should not automatically be considered equivalent to other 7320 bearing designs.

GA - Universal Matching with Light Preload

The suffix GA identifies a universally matchable bearing execution.

When compatible bearings are correctly paired in a suitable arrangement, light preload can be obtained.

This design allows bearings to be used in:

• Back-to-back arrangements.

• Face-to-face arrangements.

• Tandem arrangements.

The GA suffix does not indicate C3 radial internal clearance.

M - Machined Brass Cage

The letter M identifies a machined brass cage.

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

Its material and construction are important identifying characteristics of the BEGAM execution.

Construction of SKF 7320 BEGAM

Inner Ring

The inner ring has a cylindrical bore measuring 100 mm.

Its raceway is designed to operate with the balls at the specified contact angle.

Outer Ring

The outer ring has an outside diameter of 215 mm.

The asymmetric relationship between the inner and outer ring raceways enables the bearing to accommodate combined loads.

Steel Balls

The rolling elements are steel balls operating between the bearing raceways.

They transmit loads through rolling contact at a nominal contact angle of 40 degrees.

Machined Brass Cage

The machined brass cage maintains the correct circumferential spacing between the balls.

It separates the rolling elements and supports their guidance during operation.

Open Bearing Construction

SKF 7320 BEGAM does not incorporate integrated seals or shields.

Suitable lubrication and protection against contamination must be provided by the surrounding bearing arrangement.

Radial and Axial Load Capacity

Radial Loads

SKF 7320 BEGAM accommodates loads acting perpendicular to the shaft axis.

When selecting the bearing, the basic dynamic load rating C, basic static load rating C0 and actual operating conditions must be considered.

The load rating values should be obtained from the manufacturer's documentation for the exact SKF 7320 BEGAM designation.

Axial Loads

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

The direction of the axial load must correspond to the bearing orientation within the mechanical assembly.

Where axial loads act in both directions, a suitable bearing arrangement is required.

Combined Loads

The angular contact ball bearing design allows radial and axial loads to be accommodated simultaneously.

The 40-degree contact angle is an important factor in load distribution, bearing stiffness and arrangement selection.

Universal Matching - GA Execution

SKF 7320 BEGAM is designed for universal matching.

This characteristic is particularly important in arrangements requiring controlled preload and defined axial stiffness.

Back-to-Back Arrangement - DB

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

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

It is often considered where bearing arrangement rigidity is important.

Face-to-Face Arrangement - DF

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

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

Tandem Arrangement - DT

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.

An appropriate solution must also be provided for axial loads acting in the opposite direction.

The correct configuration depends on the complete mechanical design and operating conditions.

SKF 7320 BEGAM vs Other Bearing Executions

7320 BEGAM vs 7320 BECBM

Both designations refer to angular contact ball bearings belonging to the 7320 series.

The BEGAM version is designed for universal matching with light preload.

The CB suffix in another execution identifies a specified axial clearance characteristic when matched.

This difference affects the stiffness and operating behaviour of the bearing arrangement.

7320 BEGAM vs 7320 BEGAP

In SKF designations, M identifies a machined brass cage, while P refers to a particular polymer cage execution.

Before considering a substitution, the availability, construction and permissible operating conditions of the exact alternative designation must be verified.

7320 BEGAM vs 7320 BEGBM

The GA and GB suffixes identify different preload classes in universally matchable bearing executions.

The bearing variant should not be changed without evaluating the application requirements.

Alternative Designations and Search References

The product may be encountered under the following written forms:

• SKF 7320 BEGAM

• 7320 BEGAM SKF

• SKF 7320BEGAM

• 7320BEGAM SKF

• 7320 BEGAM 100x215x47

The complete SKF catalogue designation is 7320 BEGAM.

Other suffix combinations, including BECBM, BEGAP and BEGBM, do not represent alternative spellings of the identical bearing execution.

Typical Applications of Angular Contact Ball Bearings

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

Typical application categories include:

• Industrial machinery shafts.

• Industrial drive systems.

• Pump assemblies.

• Rotating mechanical equipment.

• Matched bearing arrangements.

• Mechanical systems requiring defined axial stiffness.

• Machinery subjected to combined loading.

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

They do not establish confirmed installation of SKF 7320 BEGAM in any specific machine model.

Industrial Shaft Support

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

The correct bearing arrangement depends on the magnitude and direction of the applied loads.

Industrial Drive Systems

Angular contact ball bearings may be used in suitable industrial drive arrangements exposed to combined loading.

Bearing selection must account for rotational speed, lubrication, mounting conditions and temperature.

Pump Assemblies

Angular contact ball bearings can support rotating shafts in pump assemblies where combined radial and axial loads occur.

The complete bearing arrangement must be designed according to the application requirements.

Matched Bearing Arrangements

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

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

Can Another Manufacturer's Bearing Replace SKF 7320 BEGAM?

An alternative may be considered after verifying equivalent dimensions, contact angle, internal construction, cage design, tolerances and matching characteristics.

Identical dimensions alone do not establish interchangeability.

Why Is the GA Suffix Important?

The GA suffix identifies a specific universal matching and preload execution.

Using a bearing with different matching characteristics may change axial clearance, preload, stiffness and the operating behaviour of the bearing arrangement.

Installation and Operation of SKF 7320 BEGAM

Preparation Before Installation

Before installation, clean the shaft, housing and mating surfaces.

Protect the bearing against contamination, moisture and mechanical damage.

Check Mounting Fits

Verify the shaft and housing tolerances.

Mounting fits influence the bearing's operating conditions and preload characteristics.

Correct Bearing Orientation

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

Its installation orientation must therefore correspond to the direction of the applied axial forces.

Installation of Matched Bearings

In back-to-back, face-to-face and tandem arrangements, the bearings must be positioned according to the intended configuration.

Incorrect installation may result in improper load distribution.

Application of Mounting Force

Do not transmit mounting force through the rolling elements.

Apply installation force to the ring being mounted with an interference fit.

Lubrication

SKF 7320 BEGAM is an open bearing.

It requires a lubricant selected according to the operating loads, rotational speed and temperature.

Storage

Store the bearing in its original packaging in a clean, dry environment.
