500X550X22 HSS8 HRadial shaft seal for heavy industrial applications, all-rubber
HSS8 seals are designed for housings with a cover plate. They use a robust design with a reinforced hard rubber seal body, and a spring-loaded sealing lip with an SKF Springcover. Their split execution enables installation where there is no access to the end of the shaft. These seals perform exceptionally well in large-size machinery, and customized or heavy-duty machinery. They are designed for industries such as metal, construction, wind energy, forestry, mining, and pulp and paper.
