💡 What is a single-lip shaft seal used for in sealed ball bearing assemblies? It keeps contaminants out and holds lubrication where bearings need it most. - Protects sealed ball bearing and linear slide unit interfaces from dust, water and debris. - Retains grease or oil on shafts to reduce wear and improve running efficiency. - Helps ceramic or steel rolling elements in engines, transmissions and industrial motion systems stay reliable.
