The CR 21670 radial shaft seals features a robust metal outer case combined with a rubber lip profile, engineered to improve pumping action and reduce heat generation at the shaft contact point. This makes it ideal for applications using oil or grease lubrication and operating at medium to high rotational speeds.
This oil seal includes a garter spring to maintain consistent radial load, ensuring long-term leak-free performance even under dynamic conditions.
