Decoding NSK 7220 BEAT85 MR
- 72Series
- Angular contact ball bearings, 72 series. Series differ in outside diameter and width even when the bore is the same.
- 20Bore
- Bore 100 mm (20 × 5).
- BEAT85 MRSuffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7220 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NSK 7220 BEAT85 MR measures 100 mm across the bore and 180 mm across the outside diameter; its width is 34 mm (100 x 180 x 34 mm).

When a shaft must handle both radial and axial forces, an NSK angular contact ball bearing is a common choice. The raceways are offset, so the balls meet them at an angle. This gives the bearing more capacity for axial load than a deep groove ball bearing of the same size. Typical equipment includes pumps, compressors, machine tool spindles and gearboxes. MR Industrial Accessories supplies this NSK line to plants and workshops across the United States and Latin America, and can help you select the correct arrangement.
The part number tells you a lot. Take 7220 BEAT85 MR, 7222 BEAT85 MR, 7322 BEAT85 MR or 7324 BEAT85 MR. The leading 7 identifies the angular contact ball series with a 40° contact angle. The next two digits relate to the outside diameter. The BEAT85 suffix covers internal details such as contact angle, cage and clearance. The MR ending shows the sales channel. If you need help reading a code, our team can explain it.
These bearings appear in petrochemical, cement, food, steel and power generation plants. You will find them in centrifugal pumps, screw compressors, gearboxes, spindles and power transmission equipment. Because they take axial load in one direction, they are often mounted in pairs so that the two bearings handle forces in both directions. We supply this NSK line to maintenance and purchasing teams throughout the United States and several Latin American countries.
Selection depends on load size and direction, speed and the environment. Where contamination is a risk, consider sealed or shielded versions. The lubricant must suit the operating temperature, and internal clearance should allow for thermal expansion without losing precision. During installation, alignment and controlled axial adjustment matter. Poor fitting can shorten bearing life.
For replacements, NSK angular contact bearings can be interchanged with other brands that use the same dimensional nomenclature. A bearing with the same numeric designation generally has the same main dimensions, but suffixes for cage, contact angle or clearance can differ. Always check the technical data before substituting. If you are unsure, we can point you to a compatible option for your application.

Frequently asked questions
- NSK 7220 BEAT85 MR bearing: what are its dimensions?
- NSK 7220 BEAT85 MR measures 100 mm across the bore and 180 mm across the outside diameter; its width is 34 mm (100 x 180 x 34 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7220.
- What does the suffix BEAT85 mean on an NSK bearing?
- It indicates internal features such as the 40° contact angle, the brass cage design and the internal clearance. These affect load capacity and limiting speed. For specific applications, contact MR.
- When should I use an angular contact bearing instead of a deep groove ball bearing?
- If the application has significant axial loads in one direction, an angular contact bearing is more suitable. If loads are mainly radial, a deep groove ball bearing may work. Also consider speed and space. MR can help you decide.
- Can I replace an NSK bearing with one from another brand?
- Yes, if the main dimensions and the load, speed and clearance specifications match. Suffixes may differ between manufacturers, so verify the technical data. MR will indicate a compatible alternative for your equipment.
