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.

Stoppen Sie Geräteausfallzeiten mit echtem Nu2340em Zylinderrollenlager

OEM manufacturers across automotive and machinery sectors face recurring challenges: counterfeit bearings causing unexpected failures, multi-layer distribution delays disrupting production schedules, and insufficient technical support increasing maintenance costs. These issues aren’t just inconveniences—they directly impact your bottom line through lost production hours and equipment damage.

Echte Nu2340em Lager: Zuverlässige Lieferkette, der Sie vertrauen können

Als offizieller -Vertriebspartner bieten wir das

Nu2340em Zylinderrollenlager mit vollständiger Rückverfolgbarkeitsdokumentation, wodurch die Risiken von Graumarktprodukten ausgeschlossen werden. Unser Echtzeit-Lagerverwaltungssystem (WMS) stellt sicher, dass dieses 200x420x138mm Lager sofort versandbereit ist, sowohl für geplante Produktionsläufe als auch für Notfall-Wartungsanforderungen in Anwendungen der Automobilmaschinen.

Optimale Leistung in Schwerlastanwendungen

Das Nu2340em Zylinderrollenlager ist für die Handhabung radialer Lasten in Maschinen mit hohem Drehmoment ausgelegt. Seine getrennte Bauweise ermöglicht eine einfache Installation und Wartung, während die Wälzlagerstahlkonstruktion Haltbarkeit im Dauerbetrieb gewährleistet. Dieses Design macht es ideal für Automobilgetriebesysteme und Industriegetriebe, bei denen eine zuverlässige radiale Lastunterstützung entscheidend ist.

Technische Merkmale, die die Anlagenverfügbarkeit maximieren

Die wichtigsten Spezifikationen des

    Nu2340em tragen direkt zur Betriebseffizienz bei. Die Genauigkeitsklassen (P0 bis P2) ermöglichen eine Anpassung an die Anwendungsanforderungen, wobei höhere Klassen Vibrationen und Geräusche in Präzisionsmaschinen reduzieren. Die Vibrationsklassen bis

    gewährleisten einen reibungslosen Betrieb über den gesamten Drehzahlbereich, während das getrennte Design einen schnellen Austausch bei Wartungsarbeiten ermöglicht und so Stillstandszeiten minimiert. Die Abmessungen von 200x420x138mm bieten eine robuste Belastbarkeit, die für schwere Nutzfahrzeuge und Industrieanlagen geeignet ist.

    Warum echte Lager die Gesamtbetriebskosten senken

    Counterfeit cylindrical roller bearings may offer lower upfront costs, but they often fail prematurely—costing far more in production downtime and equipment repairs. Our genuine NTN Nu2340em bearings come with full traceability, ensuring compliance with OEM quality standards. With ISO 9001 compliant quality inspection, each bearing meets NTN’s strict performance criteria, delivering consistent service life and reducing long-term maintenance expenses.
