Read this exact catalogue record
NTN 7322 is recorded in the manufacturer catalogue as single row or matched pairs of angular contact ball bearings. Its listed boundary dimensions are 110×240×50 mm: bore d × outside diameter D × bearing/inner-ring width B.

How to use the parameters
- Use the complete NTN marking when comparing this record. The base number alone does not establish the same closure, clearance, cage, load rating or speed across brands.
- Dynamic and static load ratings are catalogue reference values, not a permitted working load for every installation. Grease and oil speed entries describe separate lubrication conditions; do not treat the higher value as a general operating limit.
- Mounting dimensions such as shoulder diameters and maximum fillet radii are not the bearing boundary dimensions. Unknown precision, material, lubricant grade and application fitment are not inferred from similar products.
This is an independent technical reference, not an official drawing, a complete current catalogue or an approval for a vehicle or machine.
