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.

    • Rolamentos de Rolo Cilíndrico

      Quando rolamentos falsificados falham prematuramente em sistemas de transmissão automotiva, o custo vai além das peças de reposição — paradas não planejadas podem interromper linhas de produção por dias, corroendo lucros e a confiança dos clientes. Muitos fabricantes enfrentam prazos de entrega inconsistentes por parte de distribuidores em múltiplos níveis, tornando quase impossível alinhar-se com cronogramas de produção apertados. Sem suporte técnico adequado, até mesmo rolamentos genuínos podem ser mal aplicados, resultando em vida útil reduzida e custos de manutenção elevados.

      Genuínos

      • Rolamentos: Fornecimento Confiável para Máquinas Críticas

        Como distribuidor oficial

      • , fornecemos rolamentos cilíndricos de rolos

          O

            rolamento de rolos cilíndricos se destaca em aplicações que exigem alta capacidade de carga radial e velocidades moderadas. Seus anéis interno e externo separados permitem montagem e desmontagem fáceis, simplificando os procedimentos de manutenção em espaços apertados. Com classes de precisão de P0 a P2 e classes de vibração até
          • , este rolamento atende aos requisitos rigorosos da fabricação automotiva e de máquinas em geral, onde a estabilidade operacional impacta diretamente a eficiência da produção.

            Características Técnicas Que Garantem Desempenho a Longo Prazo

            The NU356EM’s bearing steel construction provides excellent durability under continuous operation, while its cylindrical structure enables efficient load distribution across the rolling elements. Available precision ratings (P0-P2) allow customization for specific application needs—P5 grade for high-speed electric motors requiring minimal runout, or P2 grade for precision machine tool spindles. The separated design facilitates thermal expansion compensation, critical in applications with temperature fluctuations, while the option for grease or oil lubrication ensures adaptability to various operating conditions.

            Por que Rolamentos Genuínos Reduzem o Custo Total de Propriedade

            Choosing authentic NTN NU356EM bearings eliminates hidden costs associated with counterfeit products. Non-genuine bearings often fail within 30-50% of expected service life, leading to repeated replacements and unplanned downtime. Our bearings, backed by NTN’s engineering expertise, maintain consistent performance over extended periods, reducing maintenance frequency and associated labor costs. Full traceability documentation ensures compliance with international export requirements, preventing customs clearance delays that can disrupt supply chains.
