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.

Stoppen Sie Produktionsverzögerungen mit echtem Zylinderrollenlager 45x100x25mm

Production lines grinding to a halt due to bearing failures isn’t just inconvenient—it’s costly. Many manufacturers face the double risk of counterfeit bearings causing premature breakdowns and multi-tier distributors stretching delivery times by 30-50%. When your automotive machinery or industrial equipment needs a reliable 45x100x25mm bearing, these delays can derail production schedules and erode profitability.

Echtes

Zylinderrollenlager
– Auf Lager und rückverfolgbar

As an official NTN distributor, we eliminate these pain points with direct access to authentic Cylindrical Roller Bearing NF309EM units. Our WMS real-time inventory system ensures your 45x100x25mm bearing is ready for immediate dispatch, while our ISO 9001 compliant three-level quality inspection guarantees batch consistency. Whether it’s for automotive transmissions or motor applications, we deliver bearings that match your exact specifications without the wait.

Entwickelt für Anwendungen mit hohen Radiallasten

Das Zylinderrollenlager ist dafür ausgelegt, in Umgebungen mit hohen Radiallasten, wie sie typisch für Fahrzeugmaschinen und Industrieanlagen sind, hervorragende Leistungen zu erbringen. Die getrennten Innen- und Außenringe ermöglichen eine einfache Montage und Wartung, während die einreihige Zylinderstruktur eine optimale Lastverteilung gewährleistet. Dies macht es ideal für den Dauerbetrieb in Getrieben, Elektromotoren und Förderanlagen, bei denen Zuverlässigkeit unter ständiger Belastung unerlässlich ist.

Technische Präzision, die Leistung antreibt

Jeder Aspekt des Lagers ist auf Leistung ausgelegt. Die Lagerstahlkonstruktion gewährleistet Haltbarkeit unter hohen Lasten, während Genauigkeitsklassen von P0 bis P2 Anwendungen mit engen Toleranzen ermöglichen. Die offene Abdichtungsbauweise erlaubt flexible Schmierungsoptionen—Öl, Fett oder Trockenlauf—und passt sich so verschiedenen Arbeitsbedingungen an. Die Abmessungen 45x100x25 mm balancieren Kompaktheit mit Tragfähigkeit aus, was es zu einer vielseitigen Wahl für platzbeschränkte Maschinen macht.

Warum Authentizität für Ihr Geschäftsergebnis wichtig ist

Gefälschte Lager mögen wie eine kostensparende Abkürzung erscheinen, führen aber oft zu versteckten Kosten: unerwartete Ausfallzeiten, erhöhte Wartungskosten und mögliche Schäden an angrenzenden Komponenten. Unsere Zylinderrollenlager werden mit vollständiger Rückverfolgbarkeitsdokumentation geliefert, wodurch Zollabfertigungsprobleme und Qualitätsstreitigkeiten vermieden werden. Durch die Investition in Originalteile verringern Sie das Risiko vorzeitiger Ausfälle und sichern eine längere Lebensdauer der Anlagen – letztendlich senken Sie Ihre Gesamtbetriebskosten.
