💡 What is a rotary shaft seal used for in bearing and pump applications? A rotary shaft seal keeps lubricant in and keeps contaminants out on rotating shafts, which is handy for extending service life and cutting maintenance. Quick overview: - Keeps lubricants inside sealed ball bearing assemblies and linear slide unit guides for smoother operation - Blocks water, dust, and debris from gearboxes, pumps, and motors to reduce wear - Low friction lip design helps maintain efficiency and reduce energy loss
