Decoding NSK 7308 BEAW
- 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).
- BEAWSuffix
- NSK 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
NSK 7308 BEAW measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm).

For equipment that must hold precision under combined radial and axial loading, the NSK BEAW series angular contact ball bearing is a single-row option. Its raceways are arranged to take axial load in one direction, which suits machine tool spindles, pumps, gearboxes and similar drives. Selecting the correct designation matters, because the series carries specific internal features that set it apart from other suffixes.
Reading the code helps you order the right bearing. In 7308 BEAW, 7309 BEAW and 7310 BEAW, the leading number grows with the bore diameter, while BEAW identifies the internal configuration, including contact angle and cage design. Treat BEAW as unique to this series and not interchangeable with other suffix combinations. If a part number is unclear, send it to our team and we will help you interpret it.
These bearings appear in machine tool spindles, centrifugal pumps, compressors, gearboxes and transmission equipment. Because they accept axial load in a single direction, they are often mounted in paired arrangements. In a plant, the selection you make affects how accurately and how long the equipment runs, so it pays to match the bearing to the actual load case rather than to the old part alone.
When choosing an angular contact bearing, review the axial load, the operating speed and the rigidity the application requires. Mounting must provide accurate alignment and the correct preload as specified by the manufacturer. Lubrication may be grease or oil, and the sealing method depends on the surrounding environment. Where axial load acts in both directions, paired mounting is the usual approach. Following the mounting instructions helps prevent early failure.
NSK BEAW series bearings can be interchanged with equivalent bearings from other brands that use the same international nomenclature. If you are holding a competitor's part number, we can identify the compatible equivalent. Because interchangeability depends on dimensions and tolerances, verify the complete designation before ordering. Our team can advise you on the right replacement.
To request a quote, send the complete part number by WhatsApp or email, for example 7312 BEAW or 7313 BEAW. We reply promptly and can suggest equivalents or help you choose if you are unsure. MR Industrial Accessories LLC supplies bearings, mounted units and housings, power transmission parts, seals, lubrication and maintenance tools to customers across the United States and in several Latin American countries.

Frequently asked questions
- NSK 7308 BEAW bearing: what are its dimensions?
- NSK 7308 BEAW 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 BEAW suffix indicate on an NSK bearing?
- BEAW identifies internal features of the bearing, such as the contact angle and the cage type. It belongs to this series and should not be confused with other suffixes. Send us the full part number and we will help you read it.
- How do I decide between an angular contact bearing and a deep groove ball bearing?
- An angular contact bearing takes axial load in one direction and provides greater rigidity, which suits combined loads. A deep groove ball bearing is intended mainly for radial loads. The decision depends on the direction and size of the loads in your application, and we can advise you.
- Can an NSK BEAW bearing be replaced by another brand?
- Yes, when the other brand offers a bearing with the same designation and dimensions. Interchangeability depends on tolerances and internal design. Send us the original part number and we will indicate the compatible equivalent and quote it.
