Full designation

Definition

A full designation is the complete identifier a manufacturer uses for a specific bearing product, including any prefixes and suffixes that encode configuration. It is distinct from the base designation, which typically identifies a series and size, and from a supplier’s own SKU.

Why it matters

Prefixes and suffixes can indicate differences such as closure type, internal clearance, cage, precision class or lubrication. Two products that share a base designation but differ in suffix are different products. Treating the base designation as the identity merges variants and leads to the wrong configuration being listed, stocked or shipped.

Suffix systems are defined by each manufacturer. The same characters can mean different things for different manufacturers, so a suffix should be interpreted using that manufacturer’s documentation rather than a cross-brand table.

Example

Illustrative, synthetic values:

A and B are variants. C is not yet identifiable: it may be a truncated designation or a product whose default configuration is documented elsewhere.

In practice

• Store the raw designation exactly as received alongside a normalized form.
• Normalize only formatting that the manufacturer treats as insignificant, such as case or separators.
• Pair the designation with a resolved manufacturer identity; designation spaces are not shared across manufacturers.

Apply it

Find exact duplicate candidates by manufacturer and full designation with the local catalog checker, read about part identification, or discuss your catalog.
