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.

Produktionsverzögerungen stoppen mit zuverlässigen hochpräzisen Axialkugellagern 51220 51320

OEM manufacturers know the frustration of unexpected downtime caused by bearing failures. Counterfeit thrust bearings often fail prematurely under heavy axial loads, leading to production line shutdowns and costly repairs. Sourcing from multi-tier distributors compounds the problem with inconsistent delivery times that disrupt manufacturing schedules. When every minute of downtime impacts your bottom line, reliable bearing supply isn’t just a convenience—it’s critical.

Echte hochpräzise Axialkugellager auf Lager für sofortigen Versand

Als offizieller

-Vertriebspartner bieten wir 100 % rückverfolgbare Hochpräzisions-Axialkugellager 51220 und 51320, die den -Standards entsprechen. Unser WMS-Echtzeit-Lagerverwaltungssystem stellt sicher, dass diese Lager auf Lager und versandbereit sind, wodurch die Verzögerungen traditioneller Lieferketten vermieden werden. Konzipiert für OEM-Anwendungen im Maschinenbau, bieten diese einreihigen Axiallager eine stabile Leistung in Automobilgetrieben, Motorbaugruppen und allgemeinen Industrieanlagen, bei denen axiale Lastaufnahme wesentlich ist.

Optimale Leistung in Anwendungen mit hoher Axiallast

Die 51220 und 51320 Axialkugellager zeichnen sich in Anwendungen aus, die eine präzise axiale Laststeuerung erfordern. Mit einem Kontaktwinkel von 0° und getrennter Bauweise bewältigen sie effizient reine Axiallasten in beide Richtungen. Ihr 100 mm Bohrungsdurchmesser und 150 mm Außendurchmesser machen sie ideal für mittelgroße Maschinen, während die 38 mm Breite eine robuste Unterstützung in Umgebungen mit hohem Druck bietet. Ob in Pressen oder Fördersystemen eingesetzt, diese Lager bewahren die Ausrichtung und reduzieren Vibrationen über die Vibrationsklassen bis

.

Technische Merkmale die langfristige Zuverlässigkeit gewährleisten

Unsere Präzisions-Axialkugellager enthalten kritische Konstruktionselemente für industrielle Langlebigkeit. Die Lagerstahlkonstruktion bietet hohe Härte und Verschleißfestigkeit, was die Lebensdauer bei Schwerlastanwendungen verlängert. Verfügbare Genauigkeitsklassen von P0 bis P2 ermöglichen eine Anpassung an Anwendungen, die enge Toleranzen erfordern – die Stufen P5 und P4 eignen sich für Hochgeschwindigkeitsmaschinen, bei denen minimaler Rundlauf entscheidend ist. Die geteilte Bauweise vereinfacht Montage und Wartung, während die Kompatibilität mit sowohl Fett- als auch Ölschmierung Flexibilität unter verschiedenen Betriebsbedingungen bietet. Diese technischen Eigenschaften sorgen gemeinsam für eine gleichbleibende Leistung auch unter schwankenden Lasten.

Warum echte Axiallager die Gesamtkosten senken

Choosing genuine ISO9001 Thrust Bearings eliminates the hidden costs of counterfeit products. Unauthorized bearings often use substandard materials that fail prematurely, leading to emergency repairs, production losses, and potential safety hazards. Our three-level quality inspection system ensures each bearing meets NTN’s strict standards, reducing the risk of unexpected failures. While counterfeit bearings may offer lower upfront prices, the long-term savings from reduced downtime and maintenance make authentic bearings a smarter investment for OEM manufacturers focused on total cost of ownership.

Unser Engagement für zuverlässige Lagerlieferung

With over 10 years of experience serving clients in 50+ countries, we’ve built our reputation on four pillars of reliability: official NTN authorization ensures full product traceability with complete documentation; our ISO 9001 compliant quality system includes incoming material inspection and pre-shipment verification; a dedicated technical team provides application support from model selection to failure analysis; and global door-to-door logistics ensures on-time delivery regardless of destination.
