Decoding SKF 7308 BEM1
- 73Series
- Angular contact ball bearings, 73 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- BEM1Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7308 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 7308 BEM1 measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm).

SKF angular contact bearings handle radial and axial loads in a single direction. The offset raceways create an oblique contact angle between the balls and raceways, which gives the bearing its axial load capacity. You will find them in pumps, compressors and spindles where precision and rigidity matter. MR Industrial Accessories supplies this line and helps you match the bearing to your equipment.
The part number tells you how the bearing is built. Take 7308 BEM1: the digits give the dimension series, then the letters and final digit describe the contact angle and internal details. B means a 40° contact angle, E a reinforced polyamide cage, M a brass cage, and 1 a specific internal design. Reading these suffixes correctly is the first step in picking a bearing that fits the application.
These bearings show up in food processing, petrochemical, steel and machine tool plants. They are common in centrifugal pumps, screw compressors, gearboxes and milling machine spindles. Because they take combined loads, they suit equipment running at moderate to high speeds, where precision and rigidity affect how the assembly performs and how long it lasts.
Selection depends on the size and direction of the loads, the rotation speed and the environment. Sealing is a key decision: open bearings need external lubrication and protection from contaminants, while sealed versions keep lubricant in and dirt out. Mounting must give precise alignment and the right internal clearance; a poor fit can lead to overheating and early failure. Use the lubricant specified by the manufacturer.
SKF angular contact bearings can be replaced by equivalents from other brands when dimensions, contact angle and load capacity match. Check tolerances and cage design, since they influence performance. For a replacement, compare the full designations and speak with a specialist to confirm compatibility. MR Industrial Accessories can help you find the right option.

Frequently asked questions
- SKF 7308 BEM1 bearing: what are its dimensions?
- SKF 7308 BEM1 measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7308.
- What does the BEM1 suffix mean in an SKF bearing?
- In 7308 BEM1, B is a 40° contact angle, E a reinforced polyamide cage, M a brass cage, and 1 a specific internal design. These suffixes define construction details that affect performance and application.
- How do I choose between a sealed and an open bearing?
- Open bearings need external lubrication and suit clean, high-speed environments. Sealed or shielded bearings retain lubricant and block contaminants, which helps in dirty or humid conditions. The choice depends on operating conditions and maintenance.
- Can I replace an SKF bearing with another brand?
- Yes, if dimensions, contact angle and load capacity are equivalent. Check tolerances and cage type, as they affect performance. Send us the original part number and we will help you find a suitable alternative.
