About KOYO Bearing Supplier

One brand, matched to the machine you are repairing.

KOYO Bearing Supplier supplies Koyo / JTEKT bearings only, for repairs on farm machinery, construction equipment and power transmission. You send the machine model, the bearing position and photos of the markings. We check the replacement reference against the application.

What we do

Koyo / JTEKT repair bearings, matched to the machine you repair.

KOYO Bearing Supplier supplies Koyo / JTEKT bearings to repair shops, fleets and parts distributors worldwide. We focus on agricultural machinery, construction equipment and power transmission, from one bearing position up to every bearing a full assembly rebuild needs.

  • Single-brand supply

    Only Koyo / JTEKT, with no other brands mixed into your order.

  • Tapered, spherical, cylindrical and needle roller bearings

    We also supply deep groove, angular contact and thrust ball bearings, so one supplier covers everything from compact drives to heavy shafts.

  • One enquiry, whole repair

    Send a machine manual, an existing bearing number or your spare parts list. We quote it all on one enquiry.

Brand covered

Koyo / JTEKT

Why one brand

Matching to one brand prevents the wrong replacement.

Working only with Koyo / JTEKT lets us discuss each replacement against the original bearing specification, not size alone. A bearing that fits by size can still be wrong for the mobile equipment position it came from.

Selection against the original specification

  • We discuss the original Koyo / JTEKT specification, not just the bore and OD.
  • Sealing, roller type and cup/cone match the position.
  • The bearing goes back into the application it came from.

Checked against machine identification

  • We check the bearing reference against the machine model and part numbers.
  • Worn markings can still be resolved from the machine plate.
  • We confirm the full assembly so the parts that must be replaced together are not missed.

Buyer-approved technical changes

  • We settle identification questions before we quote.
  • A separately identified alternative is offered only if you accept alternatives.
  • Nothing technical changes without your approval.
Who we serve

Built around the people who run the repair.

Each person on a repair job needs different information. We work with the service manager, the technician and the buyer on the same enquiry.

How we work

Identification first, then a written quote.

Each order follows the same six steps, from the first enquiry to checking the delivery, so the bearing that arrives is the one the machine needs.

What customers say

The right reference, delivered in season.

What repair shops, fleets and contractors say about getting the right reference for their machines.

"Our agricultural equipment service shop uses Koyo bearings for planters, harvesters and sprayers. This supplier provides the correct tapered, spherical and cylindrical roller bearings for each machine type, and the parts arrive in time for our busy season."
Jesse ThompsonJesse Thompson
"We run a construction equipment fleet. Koyo bearings on our excavator and wheel loader wheel ends are a critical wear item. The bearings we ordered arrived with the correct rollers and cups, and our mechanic noted the fit was exactly as expected."
Pedro AlvarezPedro Alvarez
"When a Koyo bearing failed on a harvest machine during the season, we needed a replacement urgently. The supplier identified the correct Koyo reference, shipped same-day, and the machine was back in the field within the day. That is what emergency support looks like."

FAQ

Questions from repair shops

To identify a Koyo / JTEKT replacement, we use the machine model, the bearing position and whatever markings are left, even when the stamp is partly worn away.

What should I send if the bearing markings are worn?

Send the machine model, the bearing position and photos of whatever marking is still visible, plus measured dimensions and a photo of the assembly. Even a partial stamp narrows down the reference, and we check it against the machine before quoting.

Can I include machine part numbers with my enquiry?

Yes. We check Koyo / JTEKT bearing references together with the machine model and part identification. A machine manual or spare parts list also works.

Can you quote a full assembly rebuild, not just one bearing?

Yes. One enquiry can cover one bearing position or every bearing a gearbox or axle rebuild needs. Confirming the complete assembly up front helps avoid a second shutdown for a missed part.
