💡 What is a radial shaft seal used for in sealed ball bearing, gearbox and pump applications? A radial shaft seal keeps lubricant in and contaminants out so bearings and gear trains run longer with fewer leaks. Quick overview: - Improves sealed ball bearing life by keeping lubricant sealed and dirt out - Prevents gearbox and pump oil loss under pressure, reducing downtime - Supports linear slide unit setups and ceramic bearing systems in tight fits - Low-friction single-lip design lowers wear and helps system efficiency
