Quality is handled through catalog discipline.
The catalog does not treat quality as a slogan only. It organizes selection through type codes, dimension tables, precision classes, clearance groups, material suffixes and fit recommendations.
01Type and codeConfirm bearing family, structure and designation before pricing.
02DimensionsCheck bore, outside diameter, width, Fw and radius limits from the catalog.
03Tolerance and clearancePreserve /P and /C suffixes when the application requires them.
04Materials and fitsReview material suffix and fit guidance before replacement.
Precision quality signals
Tolerance classes should be part of technical communication because dimensional and running accuracy can be application-critical.
Clearance quality signals
Clearance groups should be retained when replacing a bearing; group 0 may be omitted in some codes while /C3, /C4 and /C5 must be stated.
