How to Read This Comparison
The equivalents shown below are confirmed cross-references.
- Verified equivalent — confirmed cross-reference.
- Probable — verify fitment — likely equivalent from specification matching; confirm before ordering.
Why the Part Numbers Look Different
Each manufacturer uses a different suffix system for the same physical bearing. Here's how the 7309 suffixes map across brands:
| Feature | SKF | FAG | NSK | NTN | Timken |
|---|---|---|---|---|---|
| Rubber sealed | 7309 BE-2RZP | 7309-B-2RS-TVP | 7309A-2RS | 7309-2RS | 7309-2RS |
| Open | 7309 BEP | 7309-B-TVP | 7309A | 7309 | 7309 |

Frequently Asked Questions
Can I replace a 7309 with a different brand?
The table lists 7309 equivalents across brands. Rows marked Verified equivalent are confirmed cross-references; rows marked Probable — verify fitment are likely matches inferred from specification data. Before ordering — especially for probable rows — confirm bore, outer diameter, width, seal type, and internal clearance against your existing part.
What's the difference between a “verified” and a “probable” equivalent?
A verified equivalent is a confirmed cross-reference. A probable equivalent is inferred from matching specifications and has not been independently confirmed — treat it as a strong candidate to verify against the manufacturer's datasheet, not a guaranteed drop-in.
How do I confirm a 7309 equivalent fits?
Match bore diameter, outer diameter, width, seal type, and internal clearance to your existing part, then check the manufacturer's datasheet for the exact suffix. The dimensions for each brand are shown in the comparison table above.
