💡 What is an oil seal used for in rotary equipment and sealed ball bearing assemblies? An oil seal keeps lubricants in and stops dirt and water from getting into bearings and shafts, helping systems run cleaner and last longer. - Retains grease and oil inside housings to protect sealed ball bearing and gear interfaces. - Keeps contaminants out of motors, pumps, transmissions and linear slide unit guides to reduce wear. - Handy for maintenance: lowers downtime, extends bearing life, and cuts replacement costs.
