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 echten

Zylinderrollenlagern

OEM-Hersteller in der Automobil- und Maschinenbaubranche sind häufig mit kostspieligen Störungen durch gefälschte Lager konfrontiert, die vorzeitig ausfallen, oder unvollständige Rückverfolgbarkeitsdokumente, die zu Verzögerungen bei der Zollabfertigung führen. Mehrstufige Vertriebskanäle verlängern die Lieferzeiten oft um 30-50 %, was es nahezu unmöglich macht, sich an enge Produktionszeitpläne zu halten.

Echte

Lager: Auf Lager und rückverfolgbar

Als offizieller

-Distributor beseitigen wir diese Schwachstellen, indem wir 100 % echte
-Zylinderrollenlager mit vollständiger Rückverfolgbarkeit liefern. Unser Echtzeit-Inventarsystem WMS stellt sicher, dass dieses hochpräzise 65x140x48 mm Lager sofort versandbereit ist und sowohl geplante Produktionsläufe als auch Notfallwartungsbedarf in Anwendungen der Automobilmaschinerie unterstützt.

Entwickelt für Hochpräzisions-Maschinenleistung

Das

    Zylinderrollenlager zeichnet sich in hochbelasteten Radialanwendungen in Fahrzeuggetrieben und Elektromotorenbaugruppen aus. Seine getrennte Bauweise ermöglicht eine einfache Montage und Demontage, während die Wälzlagerstahl-Konstruktion eine außergewöhnliche Haltbarkeit unter Dauerbetriebsbedingungen bietet. Mit Präzisionsklassen von P0 bis P2 und Vibrationsklassen bis zu

    , behält dieses Lager auch in hochdrehenden Geräten seine Stabilität.

    Technische Spezifikationen, die Zuverlässigkeit gewährleisten

    Die Abmessungen des Lagers mit einem Bohrungsdurchmesser von 65 mm, einem Außendurchmesser von 140 mm und einer Breite von 48 mm sorgen für eine optimale Lastverteilung bei mittelschweren bis schweren Maschinen. Sein radiales Lastdesign macht es ideal für Getriebe und Antriebssysteme, bei denen axiale Bewegungen minimal sind. Verfügbare Genauigkeitsklassen (P0-P2) ermöglichen eine Anpassung an die Anwendungsanforderungen – von allgemeinem industriellen Einsatz (P0) bis hin zu hochpräzisen Werkzeugmaschinen (P2). Die getrennten Innen- und Außenringe erleichtern Wartung und Inspektion, ohne dass benachbarte Komponenten entfernt werden müssen.

    Warum echte Lager die Gesamtbetriebskosten senken

    Graumarktlager mögen auf den ersten Blick günstiger erscheinen, führen jedoch aufgrund vorzeitiger Ausfälle, Produktionsausfällen und Anlagenschäden typischerweise zu 3-5 Mal höheren Kosten. Unser nach ISO 9001 zertifiziertes dreistufiges Qualitätsprüfsystem stellt sicher, dass jedes

    -Lager strenge Leistungsstandards erfüllt und eine gleichbleibende Chargenqualität liefert, die unerwartete Wartungsarbeiten minimiert. Die von uns bereitgestellte vollständige Produktrückverfolgbarkeitsdokumentation beseitigt Zollabfertigungsprobleme und Haftungsrisiken im Zusammenhang mit gefälschten Produkten.
