FAQ
Ordering Koyo / JTEKT bearings: common questions
How should I submit old Koyo markings and current JTEKT part numbers?
List them side by side, exactly as they appear on the bearing or in your records. Add the gearbox model and bearing position where you can. If a marking is incomplete, attach a clear photo and note what still needs confirming.
Can you quote by quantity per unit and by total order quantity?
Yes. Send the quantity per unit for each bearing and the number of units, and both figures appear on the itemised quote. This prevents short or excess orders on multi-bearing assemblies.
Which bearing types can I order for gearbox and drive shaft work?
Tapered, cylindrical, deep groove ball, needle, angular contact, spherical roller and thrust ball bearings, all Koyo / JTEKT. Application-specific bearings can be supplied against your drawing or equipment records.
