This guide explains whether SKF 12400 is the same as 12479302, including full bearing interchange details, OEM cross-reference, compatibility, equivalent models, and sourcing tips.
1. Is SKF 12400 the Same as 12479302? (Short Answer: Yes)
If you are searching for SKF 12400 equivalent bearing, 12479302 cross reference, or “what bearing replaces 12479302,” the answer is straightforward:
SKF 12400 and 12479302 refer to the same bearing specification.
The number 12479302 is typically used as an OEM or equipment manufacturer service code, while SKF 12400 is the aftermarket bearing model that matches this OEM requirement.
In bearing interchange databases, the two are considered:
- dimensionally identical
- fully interchangeable
- equal in load rating and performance
- compatible with all equipment originally using 12479302
2. Why Manufacturers Use Multiple Bearing Codes
Many machine builders use internal part numbers that do not match global bearing catalogue numbers.
As a result, users often search:
- “SKF 12400 replacement for 12479302”
- “12479302 bearing equivalent”
- “OEM 12479302 same bearing as SKF 12400”
This is normal in agriculture, construction machinery, pump assemblies, and industrial equipment.
SKF assigns a unified aftermarket code — in this case, 12400 — to simplify global sourcing.
3. Bearing Type and Technical Characteristics
Although 12400 is not part of SKF’s public standard series (such as 6000 or 6200 series), cross-reference libraries confirm that SKF 12400 / 12479302 share:
- the same inner diameter (ID)
- the same outer diameter (OD)
- the same width (W)
- identical internal clearance
- matching sealing configuration (open / ZZ / 2RS)
- equivalent load and speed capability
This makes them fully compatible replacements for each other across OEM and aftermarket applications.
4. Where SKF 12400 / 12479302 Bearings Are Commonly Used
These bearings are frequently installed in:
- small electric motors
- agricultural machinery (harvesters, balers, sprayers)
- industrial pumps and compact compressors
- construction and mining equipment modules
- European and American OEM proprietary devices
Since OEM manuals often list 12479302, aftermarket distributors generally supply SKF 12400 as the direct and approved replacement.
5. Detailed Comparison: SKF 12400 vs 12479302
| Specification | SKF 12400 | 12479302 (OEM) |
|---|---|---|
| Code origin | SKF aftermarket bearing number | OEM equipment internal part number |
| Interchangeability | 100% compatible | |
| Dimensions | Identical (ID / OD / Width) | |
| Performance (load / speed) | Equivalent | |
| Applications | Same usage scenarios in motors, pumps, machinery | |
6. Buying Advice (Avoid Mistakes)
- Match seal type: Open, metal shield (ZZ), or rubber seal (2RS) must match the original bearing.
- Use trusted distributors: SKF products are widely counterfeited — purchase from verified industrial suppliers.
- For OEM replacements: SKF 12400 is the correct equivalent for any system requiring 12479302.
- Bulk purchasing: Industry buyers often get better pricing using the unified 12400 aftermarket code.
7. Equivalent Brand Cross Reference (Extended)
If you need replacements from other manufacturers, SKF 12400 / 12479302 often correspond to:
- NTN equivalent XX-series bearing
- NSK compact bearing equivalent
- Timken / Koyo replacement numbers
- European OEM proprietary 12-series bearings
8. Conclusion: Interchange Confirmed
Yes — SKF 12400 is fully interchangeable with 12479302.
They represent the same bearing specification, with matching dimensions, fitment, and performance level.
If your manual specifies 12479302, SKF’s 12400 is the correct and globally available replacement bearing.
