Decoding NSK 7206 B
- 72Series
- Angular contact ball bearings, 72 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- BSuffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7206 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 7206 B measures 30 mm across the bore and 62 mm across the outside diameter; its width is 16 mm (30 x 62 x 16 mm).
NSK 7206 B belongs to angular contact ball bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 7206 B and any equivalents.
Angular contact ball bearings in the NSK B series handle radial and axial loads acting in one direction. Because the raceways are offset, the balls contact them at an angle, which gives these bearings more axial capacity than a standard deep groove ball bearing. They suit shafts that need accurate guidance while transmitting axial force, as found in pumps, compressors, spindles and gearboxes.
Reading the code helps you order the right part. The four digits give the size: the first pair relates to bore diameter and the second pair to outer diameter, following the series code. Bore sizes in this range include 17 mm for 7203 B, 20 mm for 7204 B, 25 mm for 7205 B, 30 mm for 7206 B, 35 mm for 7207 B, 40 mm for 7208 B, 70 mm for 7214 B and 75 mm for 7215 B. The letter B at the end means a 40° contact angle, so the bearing takes more axial load than other versions in the series.
Typical equipment includes centrifugal pumps, screw compressors, induced draft fans, gearboxes and machine tool spindles. You will find them in food, chemical, petrochemical and process plants, as well as in power transmission arrangements that call for high axial rigidity and precise rotation.
When selecting, check the axial load, the running speed and the operating environment. Sealing matters: where dust or moisture is present, choose a variant with seals or shields. Use the internal clearance and lubrication specified for the application; grease or oil is common. Keep the shaft and housing aligned to avoid extra stress, and mount with suitable tools, without striking the rings.
Bearings from other brands with the same basic designation are often interchangeable, but confirm tolerances and contact angle, since these can differ between manufacturers. If you have a code from another brand, send it and we will help you match it. MR Industrial Accessories supplies NSK and can guide you to the correct part.

Frequently asked questions
- NSK 7206 B bearing: what are its dimensions?
- NSK 7206 B measures 30 mm across the bore and 62 mm across the outside diameter; its width is 16 mm (30 x 62 x 16 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7206.
- What does the B suffix mean on NSK bearings?
- It indicates a 40° contact angle, which increases the bearing's ability to carry axial loads in one direction. Keep this in mind when replacing the part.
- How do I decide between an angular contact bearing and a deep groove ball bearing?
- If axial loads in one direction are significant, the angular contact bearing is the better fit. For mainly radial or light combined loads, a deep groove ball bearing may work. Contact us on WhatsApp for advice.
- Can you quote the 7205 B bearing or another size in the series?
- Yes, we supply the NSK B series. Send the exact code you need, such as 7205 B, on WhatsApp or email and we will quote it promptly.
