We use a lot of NMB micro bearings. Supplier handled small qty orders with same priority as large ones, no minimum nonsense. That flexibility helped me win contracts with smaller clients.

Sold several boxes of mixed-brand wheel bearings KOYO to auto garages. Price margin is fair and the tech sheet helped our mechanics pick right cross-references.

As an industrial parts wholesaler, I need reliable lead-times. Supplier stocked TIMKEN and FAG lines and even helped with emergency air shipments for one key client — saved their production. After that, we placed quarterly blanket orders. Service impressed my purchasing team.

We handle exports to small Pacific islands; shipping is tricky. This company packed NSK bearings very securely and provided all export docs. No damage, no customs headache.
