💡 What is an oil seal used for in hydraulic pumps, gearboxes, and rotating shaft assemblies? An oil seal keeps lubricants in and contaminants out to protect bearings and shaft parts. Quick intro: - Prevents fluid leakage to maintain lubrication and pressure for sealed ball bearing setups and gearboxes. - Keeps grit and moisture away from bearing surfaces, helping sealed ball bearings, ceramic hybrids, and linear slide units run longer. - Reduces friction and heat with a low-profile single-lip design, which helps pumps, transmissions, and other high-speed shafts perform better.
