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 Rolos Cilíndricos

Os fabricantes OEM enfrentam pressão crescente quando rolamentos falsificados causam falhas inesperadas de equipamentos, custando horas de tempo de produção e milhares em despesas de reparo. Canais de distribuição em múltiplas camadas frequentemente prolongam os prazos de entrega em 30-50%, deixando as equipes de manutenção esperando por substituições críticas. Pior ainda, documentos de rastreabilidade incompletos de fornecedores do mercado cinza podem levar a atrasos na liberação alfandegária e disputas de qualidade que interrompem sua cadeia de suprimentos.

Rolamentos Originais com Inventário em Tempo Real e Rastreabilidade Total

Como distribuidor oficial da

, eliminamos essas dores de cabeça com nossa cadeia de suprimentos autorizada e sistema de inventário em tempo real WMS. O rolamento de rolos cilíndricos
    , projetado para aplicações OEM em máquinas automotivas, combina alta precisão com desempenho confiável—exatamente o que você precisa para motores, caixas de engrenagens e sistemas de transmissão. Cada unidade vem com documentação completa de rastreabilidade, garantindo conformidade com padrões internacionais de qualidade e simplificando procedimentos alfandegários.

    Projetado para desempenho de máquinas automotivas de alta precisão

    O

      rolamento de rolos cilíndricos se destaca em aplicações de carga radial, tornando-o ideal para componentes rotativos de alta velocidade em transmissões automotivas e máquinas industriais. Sua estrutura separada permite montagem e desmontagem fáceis, reduzindo o tempo de manutenção durante revisões de equipamentos. Com classificações de precisão de P0 a P2, este rolamento atende aos rigorosos requisitos de tolerância de

      automotivo, garantindo operação suave mesmo sob condições variáveis de temperatura e carga.

      Principais Características Técnicas Que Aumentam a Confiabilidade do Equipamento

      The NTN NUP2319EM’s 95*200*67mm specification balances load capacity with compact design, fitting seamlessly into tight machinery configurations. Its bearing steel construction provides excellent durability, while vibration levels (Z1V1 to Z3V3) can be selected based on noise sensitivity requirements—critical for passenger vehicle applications. The option for grease or oil lubrication offers flexibility across operating environments, from high-temperature engine compartments to industrial gearboxes. Precision ratings up to P2 minimize runout, reducing wear on mating components and extending overall equipment life.

      Por que Rolamentos Genuínos Reduzem Seu Custo Total de Propriedade

      Choosing authentic NTN cylindrical roller bearings like the NUP2319EM eliminates the hidden costs of counterfeit products. Fake bearings often fail prematurely, leading to unplanned downtime, damaged machinery, and safety risks. Our ISO 9001 compliant three-level quality inspection ensures each bearing meets NTN’s strict performance standards, delivering consistent batch quality that multi-tier distributors can’t match. Over time, the reliability of genuine bearings reduces maintenance frequency and extends service intervals, lowering your total cost of ownership despite a slightly higher upfront price.
