Principais Benefícios para Operações de Caminhões

    Alta Capacidade de Carga:

    O design otimizado de rolos de agulha suporta cargas radiais pesadas, reduzindo o desgaste em trens de força de caminhões.

    Economia de Espaço:

    Dimensões compactas (285×320×60mm) cabem em compartimentos de motor apertados sem comprometer a resistência.

    Longa Vida Útil:

    A construção em aço para rolamentos resiste à corrosão e à fadiga, minimizando o tempo de inatividade para manutenção.

    Lubrificação Versátil:

    Compatível com graxa ou óleo para adaptabilidade a diversos ambientes operacionais.

    Engenharia de Precisão:

    Disponível em graus de precisão P2-P0 para rotação suave e vibração reduzida.

Perfeito para sistemas de caminhões pesados

Ideal for integration in:

  • Transmission assemblies

    • Unidades diferenciais

    Rolamentos de cubo de roda

    PTO (Tomada de Força) sistemas
