Questions buyers ask before ordering

Are these genuine NSK bearings?

Yes. Feed Mechanisms Company offers authorized NSK supply, and bearings ship in original NSK packaging. The documents for your order are confirmed in the written quotation.

My repair list only shows a short stock code. Can you still quote?

Yes, but first we confirm the exact structure. Send the machine model, the bearing position and a clear photo of the old bearing's markings, and we will confirm the full reference before quoting.

Can you supply matched sets for spindle positions?

Yes. State in your enquiry that the position needs a matched set, and give the preload arrangement. We confirm the set and preload before dispatch.
