Questions buyers ask about this bearing

What information do you need if the suffix is missing?
Send the equipment model, the bearing position and a clear photo of the markings on the bearing. Mark which details still need confirming. We complete the configuration and assembly details before quoting, and any technical change needs your approval.
Can bearings and mounting components go in one inquiry?
Yes. List adapter sleeves, housings and related mounting components in the same inquiry as the bearing, each on its own line. The written quotation then covers the whole assembly, so no part is missing at the shutdown date.

Gearbox workshops confirm the reference fit before quoting

KOYO Bearing Supplier checks mixed lists by shaft position before quoting, so each Koyo bearing arrives matched to its place in the assembly.
