Decoding NSK 7321 BEAT85 T7
- 73Series
- Angular contact ball bearings, 73 series. Series differ in outside diameter and width even when the bore is the same.
- 21Bore
- Bore 105 mm (21 × 5).
- BEAT85 T7Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7321 is the standard ISO basic designation, which sets the bearing type, series and bore.

Angular contact ball bearings in the NSK BEAT series handle radial and axial forces applied from one direction. Their raceway geometry supports elevated rotational speeds while maintaining accuracy, which makes them suitable for spindles, pumps, compressors and gearboxes. MR Industrial Accessories supplies these bearings and assists with selection.
The reference code combines a numeric prefix that denotes size and dimension series, such as 7203, 7204, 7205 or 7321, followed by BEAT, which points to design details like contact angle and cage type. A suffix such as T7 can indicate tolerance class or internal clearance. Because these details vary by reference, confirming them with our technical staff is recommended.
Typical installations include milling and lathe spindles, centrifugal pumps, air compressors, gearboxes and transmission equipment. Since the bearing accepts axial load in a single direction, it is often mounted in pairs so that the two bearings together handle forces from both directions.
Selection depends on the axial load direction, the speed of rotation and the operating environment. Proper mounting calls for accurate alignment and suitable lubrication, whether grease or oil. Protection against contamination may require seals or additional shielding in dirty conditions. Internal clearance should match the expected working temperature and fit type.
Interchange with equivalent bearings from other manufacturers is possible when the boundary dimensions, contact angle and load rating correspond. Tolerances and internal clearance also need to be checked, as minor differences can influence performance. Our team can identify a compatible reference if you provide the original part number.

- NSK 7321 BEAT85 T7 measures 105 mm across the bore and 225 mm across the outside diameter; its width is 49 mm (105 x 225 x 49 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7321.
- What does BEAT indicate in NSK bearings?
- BEAT is an internal NSK code for angular contact bearings with particular design features, including contact angle and cage. For details on a specific reference, consult our technical team.
- How do I select the correct angular contact bearing?
- Consider load magnitude and direction, rotation speed, lubrication and the working environment. Our team can advise you based on your application data.
- Can an NSK BEAT bearing be replaced by another brand?
- Yes, if the main dimensions, contact angle and load capacity align. Always verify tolerances and internal clearance. Send us the original part number and we will suggest a compatible alternative.
