  • 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.

  • Logistics notes were detailed which speeds up customs clearance — big plus.

  • 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.
