Quote by part number

Marking, label or manual reference — either brand name.

Koyo or JTEKT on your record — we handle both

Whichever brand name appears in your maintenance record or on the old part, send it as it is. We work with Koyo and JTEKT references and match them for you, so a name mismatch between maintenance and purchasing does not stall the order.

Koyo

  • Brand name often found on older bearing markings
  • Common in maintenance logs and repair records
  • Send the reference exactly as it is marked

JTEKT

  • Brand name a buyer may search under
  • Current replacement references can carry this name
  • We confirm the match before quoting

Start from the information you already have

You do not need a confirmed current part number to enquire. A body marking, a packaging reference or equipment details with a clear photo are enough for us to begin bearing identification.

Bearing body marking

Solves: the record says Koyo, purchasing searches JTEKT.

  • Send every marking on the ring or shield
  • Either brand name is accepted
  • We confirm whether it is the same part

Packaging reference

Solves: body marking and box label do not agree.

  • Send both the label and the marking
  • We check which reference to order
  • Differences are stated before quoting

Equipment or vehicle info + clear photo

Solves: worn or superseded part numbers.

  • Send a clear photo and the dimensions
  • Add equipment manual or vehicle details
  • We identify the current reference

Koyo / JTEKT bearing categories

We supply Koyo / JTEKT tapered, cylindrical and spherical roller bearings, deep groove, angular contact and thrust ball bearings, needle roller bearings and application-specific automotive references, so you can source a mixed list from one brand family.

Featured Koyo / JTEKT bearings

These featured references can be quoted by part number. Open a product to send the reference with your quantity and destination, and we reply with a written quote.

Identification checks before we quote

Before a quote is accepted, we fill in the identification details that decide whether the bearing fits. This lowers the risk of ordering the wrong execution or an incomplete assembly.

Execution and assembly scope

  • 01

    Confirm the exact execution

    Variations such as seals, clearance or cage type are checked against your reference.

  • 02

    Complete assembly or single component

    We confirm whether you need the full set, for example cone and cup together, or one part.

Alternatives and technical changes

  • 03

    Alternative references are marked separately

    If a superseded or end-of-life reference has a replacement, it is listed as a separate line, never swapped silently.

  • 04

    Technical changes need buyer approval

    Any change from the reference you sent goes ahead only after you approve it.

What your written bearing quote includes

Every written quote states the reference, quantity, price and currency, stock status, estimated lead time, validity period and the shipping and tax terms that apply, so purchasing can approve it without another round of questions.

Bearing identification FAQ

These are the questions buyers ask most often before sending a Koyo / JTEKT enquiry.

The brand on the bearing and the box label do not match. What should I send?

Send both: every marking on the bearing body and the full reference on the packaging label, plus a clear photo of each. Koyo and JTEKT names can both appear on records for the same application, and we check which reference to quote. If there is any difference, we state it before you accept the quote.

What extra information do automotive or specialised parts need?

Add vehicle or equipment identification details along with any marking you have. Application-specific automotive references can only be confirmed when we know what they fit. Include quantity, destination country and postcode, and your required delivery date.
