Radial shaft seal with low cross-sectional height for needle roller bearings, SD design

Radial shaft seals with low cross-sectional height are intended for bearing arrangements that incorporate needle roller bearings. These contact seals are designed without garter springs. SD design seals have a larger primary seal lip and a smaller auxiliary dust lip. The lips are made of polyurethane and the reinforcement ring is made of polyamide instead of metal.

• Low cross-sectional height
• Retain the lubricant
• Exclude contaminants
• Additional protection via auxiliary lip
