Selection Tips

Old Koyo marks and JTEKT references are both accepted.

Submit whichever reference is on your bill of materials or purchase records, so legacy and current part numbers end up on one list. For tight bearing positions, include the dimensions as well as the bore size.

Send Your Bearing List

  • Both references

    Give the old Koyo mark next to the JTEKT number when you have both. Each line gets checked against the gearbox model.

  • Tight positions

    For needle roller and other space-limited positions, add bore, outer diameter and width. Bore size alone is not enough.

  • Worn markings

    If a part number is incomplete, attach a clear photo of the markings and note what still needs confirming.
