SECTION 11 / FAQ

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.

Q.06 Can you ship under DDP terms to my country?

Yes. We support EXW, FOB, CIF, CFR, and DDP terms. Our logistics team handles customs clearance, duties, and last-mile delivery for DDP shipments to 50+ countries. For sensitive markets, we recommend DDP to avoid customs delays.

Stoppen Sie Produktionsverzögerungen mit echten

    6815zz Rillenkugellagern

    OEM-Hersteller kennen die Kosten von Lagerausfällen: ungeplante Stillstände durch gefälschte Teile, verspätete Lieferungen von mehrstufigen Händlern und Lücken im technischen Support, die einfache Austausche zu Produktionsstillständen werden lassen. Wenn Ihre Maschinen von Präzisionsrotation abhängen, untergräbt jede Stunde Stillstand die Rentabilität.

    Echte

      Lager, auf Lager und versandbereit

      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.

      Konstruiert für Hochgeschwindigkeits-Maschinenleistung

      Das

    • 6815zz Rillenkugellager zeichnet sich in Anwendungen aus, die eine gleichbleibend hohe Drehzahl erfordern. Mit einem Kontaktwinkel von 0° und einreihiger Bauweise bewältigt es effizient Radiallasten in Geräten, die bei erhöhten
        betrieben werden. Ob in Elektromotorspindeln oder Präzisionsmaschinen – sein geräuschloser Betrieb und die lange Lebensdauer reduzieren Wartungsunterbrechungen und halten Ihre Produktionslinie reibungslos in Gang.

        Technische Details, die Zuverlässigkeit definieren

        Drei kritische Parameter zeichnen dieses Lager aus: Genauigkeitsklasse, Spiel und Material. Es ist in den Genauigkeitsklassen P0 bis P4 erhältlich und eignet sich für Anwendungen von allgemeinen Maschinen (P0) bis zu hochpräzisen CNC-Geräten (P4). Die Spieloptionen (C0/C2/C3) ermöglichen eine Anpassung an die Anforderungen der Wärmeausdehnung – das C3-Spiel ist ideal für Umgebungen mit hohen Temperaturen, in denen Wellenwachstum auftritt. Hergestellt aus hochwertigem Wälzlagerstahl, bietet es die nötige Haltbarkeit, um den Dauerbetrieb in industriellen Umgebungen zu überstehen.

        Die wahren Kosten der Wahl nicht rückverfolgbarer Lager

        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.

        Warum globale Hersteller auf unsere -Lieferung vertrauen

        With 10+ years serving OEM clients across 50+ countries, we’ve built our reputation on four pillars: 100% genuine products with complete traceability documentation, stable bulk supply supported by dedicated inventory reservation, professional technical team assistance for model selection and failure analysis, and global door-to-door logistics with real-time shipment tracking.
