Read this exact catalogue record
NTN UCT211 is recorded in the manufacturer catalogue as bearing units.
Reference:NTN Europe public product catalogue; source checked 2026-10-01.
How to use the parameters
- Check the component or assembly description and the dimension symbols in the table. A unit, separate ring or one-way mechanism must not be treated as a standard interchangeable d×D×B bearing.
- 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.
