Single Lip Contour Riding Seal

AS: Single Lip Contour Riding Seal

This example (see illustration AS) shows a single lip contour riding seal without trash guard protection. Contour refers to the step machined into the inner ring O.D. to provide a surface for the seal lip to contact and ride against. This seal offers less contact pressure than other seals and therefore is preferable for higher speed applications, but it has less sealing capacity than other NTN insert bearing seals. This seal is primarily used on the AS series insert bearing.
