Frequently Asked
Questions

Common questions from OEM and distributor partners. Can't find an answer? Contact our engineering team directly.

Ask a custom question
Q.01 How can I verify the authenticity of NTN bearings I receive?

Every NTN bearing has laser-engraved batch codes on the inner ring. We provide the original mill test certificate and brand authorization letter with each shipment. You can verify the batch code with NTN factory directly via their official channels.

Q.02 What is the typical lead time and minimum order quantity?

In-stock items ship within 5-7 working days. MOQ starts from 1 piece for samples. Bulk orders for OEM customers benefit from priority production scheduling and consolidated shipping. Custom non-standard bearings typically take 30-45 days.

Q.03 Do you offer OEM customization (clearance, sealing, precision)?

Yes. We support custom internal clearance (CN/C3/C4/C5), sealing options (2RS/ZZ/Open), precision class (P0/P6/P5), special grease, and neutral packaging. Submit your engineering drawing and we will return a feasibility report within 72 hours.

Q.04 What documentation is provided for international shipping?

Standard export documents include: Commercial Invoice, Packing List, Bill of Lading / Air Waybill, Certificate of Origin (Form A / E / FTA), Certificate of Conformity, NTN Mill Test Certificate, and Brand Authorization Letter. Customs HS code and country-specific requirements are pre-checked.

Q.05 What is your warranty and return policy?

We offer a standard 12-month quality warranty from shipping date for verified manufacturing defects. Defective products are replaced free of charge. Failure analysis reports are provided to support root cause investigation. Wear due to misapplication or improper installation is excluded.

Arrêtez les retards de production avec les roulements à billes à gorge profonde

    6815zz authentiques

    Les fabricants OEM connaissent le coût d'une défaillance de roulement : temps d'arrêt imprévu dû à des pièces contrefaites, livraisons retardées de la part de distributeurs multi-niveaux, et lacunes du support technique qui transforment de simples remplacements en arrêts de production. Lorsque vos machines dépendent d'une rotation de précision, chaque heure d'arrêt érode la rentabilité.

    Roulements

      d'origine, en stock et prêts à expédier

      As an official NTN distributor, we eliminate these pain points with direct access to NTN’s OEM supply chain. Our WMS system maintains real-time inventory of high speed NTN 6815zz bearings, ensuring you get the exact part you need without waiting for overseas shipments. Each bearing undergoes ISO 9001 compliant three-level quality inspection, guaranteeing it meets the performance standards required for your motor or machinery applications.

      Conçu pour les performances des machines à grande vitesse

      Le roulement à billes à gorge profonde

    • 6815zz excelle dans les applications nécessitant une rotation à grande vitesse constante. Avec un angle de contact de 0° et une conception à une rangée, il gère efficacement les charges radiales dans les équipements fonctionnant à des
        élevés. Que ce soit dans les broches de moteurs électriques ou les machines de précision, son fonctionnement à faible bruit et sa longue durée de vie réduisent les interruptions de maintenance, permettant à votre ligne de production de fonctionner sans problème.

        Détails techniques qui définissent la fiabilité

        Trois paramètres critiques distinguent ce roulement : la classe de précision, le jeu et le matériau. Disponible dans les classes de précision P0 à P4, il convient aux applications allant des machines générales (P0) aux équipements CNC de haute précision (P4). Les options de jeu (C0/C2/C3) permettent une personnalisation en fonction des besoins de dilatation thermique—le jeu C3 est idéal pour les environnements à haute température où il y a une croissance de l'arbre. Construit en acier pour roulements de haute qualité, il offre la durabilité nécessaire pour résister à un fonctionnement continu dans des environnements industriels.

        Le véritable coût du choix de roulements non-traçables

        Gray-market bearings may offer lower upfront prices, but the hidden costs are substantial. Counterfeit NTN 6816zz bearings often fail prematurely due to substandard materials, leading to equipment damage and production losses that dwarf initial savings. Our fully traceable supply chain eliminates this risk—each bearing comes with documentation linking it to NTN’s manufacturing process, ensuring compliance with export customs requirements and quality liability protection.
