- 72Series
- Angular contact ball bearings, 72 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- BEA T85MR, T7Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7208 is the standard ISO basic designation, which sets the bearing type, series and bore.

Angular contact ball bearings from NSK handle radial and axial loads together, acting in one direction. Because the raceways are offset and the balls meet the rings at an angle, these bearings run at high speed while carrying substantial thrust. Machine tool spindles, pumps, compressors and gearboxes are typical homes for them. MR Industrial Accessories LLC supplies them and assists with selection.
Reading the part number helps you order the right piece. The basic number covers size: the first pair of digits gives the bore diameter and the second pair the dimension series. B stands for a 40° contact angle, while EA signals a high-capacity polyamide cage. In the suffix, T85MR means a polyamide cage rated for working temperatures up to 85 °C, and T7 means a polyamide cage with high-temperature lubrication. Reference examples are 7208 BEA T85MR, T7 and 7309 BEA T85MR, T7.
Where do these bearings show up? Metalworking shops, petrochemical plants, food processing lines and general process industries rely on them. You will find them in milling machine and CNC lathe spindles, centrifugal pumps, screw compressors, gearboxes and transmission cases, as well as in mining, cement and paper equipment. Since each bearing takes axial load in a single direction, they suit paired arrangements in which two opposed units share the load in both directions.
Selection comes down to the axial and radial load, the rotation speed and the surrounding conditions. Bearings are available open or with shield plates; where contamination is a concern, sealed variants are the better fit. Internal clearance and lubrication deserve attention, because correct lubrication is what keeps service life where it should be. On mounting, align the supports properly and apply the recommended preload to reach the rigidity the application needs. Our team can walk you through this.
Interchange between brands is possible when dimensions and contact angle line up, though tolerances and capacities can differ from one maker to another. If you are holding a part number from a different brand, send it over and we will point you to the compatible alternative. MR Industrial Accessories LLC supplies NSK alongside other leading brands and can guide you to a suitable replacement.
Quotes are simple: send the part number or the exact size through WhatsApp or email. The team responds promptly and can suggest equivalents or help you choose. Reach out whenever you need a hand.

Frequently asked questions
- NSK 7208 BEA T85MR, T7 bearing: what are its dimensions?
- NSK 7208 BEA T85MR, T7 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 18 mm (40 x 80 x 18 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7208.
- What does the T85MR suffix mean on an NSK bearing?
- It identifies a polyamide cage able to withstand temperatures up to 85 °C. Staying within that limit avoids deformation and early failure.
- How do I choose between a 72 and a 73 bearing?
- The 72 series has a smaller section than the 73, so it carries less load but permits higher speeds. What you pick depends on the load and the space available. Contact us and we will advise.
- Can I replace a bearing from another brand with an NSK one?
- Yes, provided dimensions, contact angle and load capacity match. Send us the original part number and we will indicate the NSK or other brand equivalent that fits best.
