- 00Bore
- Bore 10 mm: by standard, 00 designates 10 mm.
- BWSuffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.

The NSK BW series angular contact ball bearing handles combined radial and axial loads in a single direction. Its contact angle gives it the precision and rigidity needed for machine tool spindles, pumps, and gearboxes. MR Industrial Accessories LLC helps you select the right bearing and provides a quote when you send the part number.
Reading a BW series code is straightforward: the first number gives the bearing size, and the BW suffix indicates a pressed steel cage with a 40° contact angle. For instance, the 7200 BW has a 10 mm bore, while the 7213 BW has a 65 mm bore. These designations let you quickly confirm the main dimensions and mounting characteristics.
These bearings appear in machine tool spindles, centrifugal pumps, compressors, speed reducers, and transmission equipment. Because they take axial load in one direction, they are often mounted in pairs to handle forces in both directions. Food processing, petrochemical, and metallurgical operations rely on them for precision and dependability.
Selecting a BW series bearing requires attention to the axial load direction, operating speed, and lubrication conditions. Shaft and housing alignment must be precise, as these bearings are sensitive to misalignment. Use suitable tools during mounting to avoid raceway damage. Grease or oil lubrication is possible depending on the application, and sealing depends on the working environment.
Angular contact bearings from other brands with similar designations may be interchangeable, but always check tolerances and the contact angle. If you have a code from another brand or an unidentified part, MR Industrial Accessories LLC can identify a compatible alternative and quote it. Send us the exact code you need.

Frequently asked questions
- What does the BW suffix mean on NSK bearings?
- The BW suffix indicates a pressed steel cage and a 40° contact angle, which affects axial load capacity and rigidity.
- How do I choose between an angular contact bearing and a deep groove ball bearing?
- If your application has significant axial loads in one direction, an angular contact bearing is more suitable. For mainly radial loads, a deep groove ball bearing may be sufficient. Contact us for advice.
- Can I replace a bearing from another brand with an NSK BW series bearing?
- In many cases yes, but verify dimensions and contact angle. Send us the original part code and we will identify the equivalent and quote it.
