Selection by shaft position

Specify NTN gearbox bearings by shaft position, not just size.

NTN Bearing Supplier quotes each bearing against its position in the reducer — input, intermediate or output shaft, locating or non-locating end — so the overhaul list matches the original NTN specification.

Enquiry FAQ

What should a complete reducer bearing list include?

A complete list gives the reducer model, each shaft position, the full NTN designation with suffix, any paired arrangement and the quantity per position. Add the overhaul parts drawing, destination country and postcode, and the required delivery date. Where a marking is incomplete, attach a clear photo of it.

How should paired bearings be identified in an enquiry?

List paired bearings as one set with their arrangement, not as separate single items. State the shaft position and the full suffix for each bearing in the pair. This keeps the pairing and arrangement requirement in the quote.

Will you substitute a different bearing without asking?

No. Any technical change needs the buyer's approval, and alternatives are always marked separately in the quote. The original NTN designation stays the reference throughout.
