Koyo / JTEKT bearings, quoted by part number
Part Number Company is a Koyo / JTEKT bearing supplier serving industrial, drivetrain and aftermarket buyers worldwide. Send the marking on the bearing body, the packaging reference or the number in your equipment manual — we identify the part and return a clear written quote.

Koyo / JTEKT bearing categories
We supply Koyo / JTEKT ball, tapered, cylindrical, spherical and needle roller bearings within one brand family, so a mixed replacement list can be sourced from a single supplier. Choose a category or send your reference directly.
Bearing types and typical applications
Each Koyo / JTEKT bearing type matches a typical duty: tapered roller bearings for industrial and transmission systems, spherical roller bearings for heavy-duty assemblies. Use the table to check which information to send with your enquiry.
| Bearing type | Typical application | What to send for a quote |
|---|---|---|
| Tapered roller bearings | Industrial equipment and transmission / drivetrain systems | Body marking or packaging reference; equipment information if the part is from a drivetrain |
| Deep groove ball bearings | General machinery | Part number from the bearing, label or equipment manual |
| Cylindrical roller bearings | Shaft and gearbox applications | Reference plus the execution shown on the marking |
| Spherical roller bearings | Heavy-duty assemblies | Reference and whether a complete assembly is required |
| Needle roller bearings | Compact mechanisms | Marking or packaging reference; clear photo if worn |
| Angular contact ball bearings | Quoted against the reference on your existing part | Full marking from the bearing body and label |
| Thrust ball bearings | Quoted against the reference on your existing part | Full marking from the bearing body and label |
| Application-specific automotive bearings | Vehicle and vehicle-related aftermarket parts | Vehicle or equipment identification details are required to confirm fit |
Koyo / JTEKT bearings by part number
Every listed bearing can be quoted by its part number. Open an item to check the reference, or send the number from your stock list for a written quote.
Part number identification service
If you cannot read, find or match a reference, we identify the Koyo / JTEKT part from what you have: a photo, dimensions, an old number or a mixed brand record. Identification is completed before we quote, so you order the right part.
Worn or unreadable part number
Send a clear photo of the bearing and its dimensions. We use them to identify the correct Koyo reference.
- Photo of the bearing body and any remaining marking
- Measured dimensions
- Equipment it was removed from
Superseded reference
When an old Koyo number has been superseded, we find the current reference and the interchange details before you order.
- Old part number from records or packaging
- Current reference and interchange information
- Any technical change approved by you first
Koyo and JTEKT used for the same part
Your maintenance record may say Koyo while purchasing searches JTEKT, or the body marking may differ from the packaging label. Send both — we match them to one reference.
- Marking on the bearing body
- Reference on the packaging label
- Number from the equipment manual
Application-specific automotive bearings
Automotive bearing references need vehicle or equipment identification before we can confirm a part fits. Without it, an application-specific bearing cannot be confirmed, so we ask for these details before quoting.

Mixed Koyo / JTEKT lists in one enquiry
You can submit a mixed list of Koyo and JTEKT part numbers at once. We match each reference, confirm any execution variations and flag references approaching end-of-life with a suggested replacement series — so your buyer follows up less.
- Paste part numbers straight from your stock list
- Execution variations confirmed per line
- End-of-life notice for long-term spares planning
Each line of your list comes back with its matched reference, any execution variation and, where relevant, an end-of-life note with a suggested replacement series.
