How to read NSK 7209 BW
- 72Series
- Angular contact ball bearings, 72 series. For the same bore, each series has a different outside diameter and width.
- 09Bore
- 45 mm bore: 09 × 5.
- BWSuffix
- NSK suffix: it defines the variant (sealing, cage, internal clearance or other features).
7209 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The NSK 7209 BW bearing has a 45 mm bore, a 85 mm outside diameter and a 19 mm width (45 x 85 x 19 mm).

The NSK BW series angular contact ball bearing is a component designed to support combined radial and axial loads in a single direction. Its contact angle design makes it suitable for applications requiring high precision and rigidity, such as machine tool spindles, pumps and gearboxes. At MR Accesorios Industriales we advise you so you can choose the right bearing for your application, and we quote it for you on WhatsApp.
The BW series designation is read as follows: the initial number indicates the bearing size, and the suffix BW indicates a pressed steel cage and a 40° contact angle. For example, the 7200 BW has a 10 mm bore, while the 7213 BW corresponds to 65 mm. These codes let you quickly identify the main dimensions and mounting characteristics.
These bearings are used in a wide variety of industrial applications in Argentina, such as machine tool spindles, centrifugal pumps, compressors, speed reducers and transmission equipment. Their ability to support axial loads in one direction makes them ideal for paired arrangements, where two bearings are combined to absorb forces in both directions. Industries such as food processing, petrochemical and metallurgical use them for their reliability and precision.
To correctly select a BW series angular contact bearing, take into account the direction of the axial load, the operating speed and the lubrication conditions. It is essential to ensure precise alignment between the shaft and the housing, since these bearings are sensitive to misalignment. Mounting must be done with suitable tools to avoid damage to the raceways. Lubrication can be with grease or oil, depending on the application, and sealing will depend on the working environment.
As for equivalents, angular contact bearings from other brands with similar designations may be interchangeable, but always verify the tolerances and the contact angle. If you bring the code from another brand or an unidentified part, at MR Accesorios Industriales we tell you the compatible alternative and quote it for you. Do not hesitate to ask us about the exact code you need.

Frequently Asked Questions
- What are the dimensions of the NSK 7209 BW bearing?
- The NSK 7209 BW bearing has a 45 mm bore, a 85 mm outside diameter and a 19 mm width (45 x 85 x 19 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 7209.
- What does the BW suffix mean on NSK bearings?
- The BW suffix indicates that the bearing has a pressed steel cage and a 40° contact angle. This influences the axial load capacity and the rigidity of the arrangement.
- 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, the angular contact bearing is more suitable. For mainly radial loads, a deep groove ball bearing may be enough. Ask us and we will advise you.
- Can I replace a bearing from another brand with an NSK BW series bearing?
- In many cases yes, but it is important to verify the dimensions and the contact angle. If you send us the code of the original part, we tell you the equivalent and quote it for you.
