Bearing Designation Guide
Read a bearing designation as a complete reference. The base designation identifies a product series and size; additional letters or suffixes identify configuration details. Suffix conventions can vary between manufacturers.
HCT example: 6205-2RS/C3
- 6205: the base bearing reference.
- 2RS: two rubber contact seals, one on each side, in this HCT designation.
- C3: greater than normal internal clearance.
Information to retain
Copy the entire marking, including spaces, hyphens, slashes and suffixes. Include the manufacturer when asking for a specific branded product. A partial base model may leave important details unspecified.
When the marking is unclear
Send a clear photograph of both rings and packaging, the measured dimensions and the machine reference. Do not infer an unreadable suffix from another bearing that looks similar.
Cross-brand requests
State whether an exact original reference is required or alternatives may be reviewed. A similar suffix string is not automatic evidence of equivalent construction.
Discuss your bearing requirement
Send the complete designation, quantity, equipment details and operating conditions. We will review the reference and confirm the sourcing option before quotation.
