Bearing Cross Reference: How to Order by the Number on the Bearing You Already Use
Almost every bearing NKEN sells replaces a bearing the buyer already has — usually carrying a number from another maker. Because bearing dimensions are standardised worldwide, cross-referencing is exact engineering, not approximation. This guide shows how it works and how to get a quotation in one email.
A designation is a specification
A bearing number encodes type, size series, bore, and — in the suffixes — seals, clearance, cage and special executions. 6206-2RS C3 means: deep groove ball bearing, 62 series, 30 mm bore, sealed both sides, C3 clearance. Its boundary dimensions (30 × 62 × 16 mm) are identical whoever makes it. The same logic runs through the NKEN model library: our spherical roller table lists 22314CA/W33 with its dimensions and load ratings; our tapered catalogue holds 306 metric models, 416 inch cone & cup sets and 311 SET kits; the hub library holds 194 DAC wheel-bearing references with full dimensions.
The three places cross-references matter most
- Inch tapered sets: quote the cone/cup pair — LM67048/LM67010 is NKEN SET6. Our library indexes the full SET range this way.
- Insulated motor bearings: quote the base number plus the insulation suffix (its VL / J20 class designation) — so the coating position is matched, not guessed.
- Wheel hub units: quote the vehicle model or the unit number on the old bearing; fitment is confirmed before dispatch.
Send these five things for a one-step quotation
- The full designation exactly as marked — including suffixes (2RS, C3, W33, VL0241…).
- Quantity per item (and whether it repeats monthly).
- Destination city/country, so freight is quoted with the goods.
- Any execution requirements: brand marking, box design, grease, certificates.
- For non-standard parts: a drawing or sample dimensions (bore, OD, width is enough to start).
With those five, a cross-reference quotation is a lookup, not a research project — which is how NKEN keeps a stock range of 2,000+ models moving to distributors in 73+ countries.
Try it: enter your current bearing number in the finder on our home page, or send it through any product page inquiry form — for example the tapered roller bearings page if you run axle sets. For insulated designations, see the insulated bearings guide.
