4. NOTAS TÉCNICAS E DIFERENCIAIS

Aplicações Marítimas: Compatível com Mercury Marine e motores marítimos devido à vedação dupla que impede a oxidação interna por névoa salina.
Indicação de Montagem: Este rolamento é o parceiro ideal do modelo 6303 na maioria dos alternadores Bosch modernos. Verifique sempre se a folga interna C3 é exigida pela aplicação (comum em alternadores que operam acima de 12.000 RPM).
Vedação 2RS: Garante que a graxa lubrificante permaneça dentro do rolamento mesmo sob vibração severa em motores diesel de alta compressão.
