Basic designation
A code such as 6205 identifies a bearing series and bore-size combination within the manufacturer's designation system. Do not assume that the basic number alone captures every required feature.
Suffixes matter
Common suffix families can indicate seals, shields, internal clearance, cage, precision or other design features. Examples seen in the market include 2RS, ZZ/2Z and C3, but exact suffix meaning can vary by manufacturer and product family.
What to send in the RFQ
- Full designation exactly as marked on the bearing or packaging
- Manufacturer preference: SKF, FAG, NSK, NTN, Timken, etc.
- Quantity
- Equipment/application if known
- Photos of markings and packaging when authenticity or identification matters
- Any required clearance, precision or certification
Example: Do not shorten
6205-2RS-C3 to 6205 in an RFQ. The omitted suffixes may change the supplied configuration.Brand interchange
Cross-referencing between manufacturers should be verified against dimensions and technical characteristics. Similar-looking designations do not automatically guarantee identical performance or specification.
