HS7 seals are designed for housings with a cover plate. They have a spring-loaded sealing lip with a control wire and 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 the mining industry.
