RODAMIENTOS DE AGUJAS

Os rolamentos de rolos de agulhas SKF têm rolos cilíndricos de diâmetro pequeno em relação a seu comprimento. As extremidades dos rolos são levemente abauladas para modificar a linha de contato entre as pistas e os rolos. Isso evita picos de tensão nas extremidades do rolo, levando ao prolongamento da vida útil do rolamento. A despeito de sua seção transversal baixa, os rolamentos de rolos de agulhas possuem uma alta capacidade de carga. Portanto, são extremamente indicados para arranjos de rolamentos onde o espaço radial é limitado.
A SKF fornece rolamentos de rolos de agulhas em diferentes perfis e em uma ampla variedade de materiais, séries e tamanhos, o que os torna apropriados para diversas aplicações e condições operacionais.

SKF needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The ends of the rollers are relieved slightly to modify the line contact between the rollers and raceways. This prevents stress peaks at the roller ends to extend bearing service life. In spite of their low cross section, needle roller bearings have a high load carrying capacity. Therefore, they are extremely suitable for bearing arrangements where radial space is limited.
