💡 What is a sealed ball bearing used for in washdown and conveyor systems? A sealed ball bearing keeps contaminants out and lubrication in, helping gearboxes, conveyors, and washdown lines run longer with less maintenance. - Ideal for damp, wet, or food-processing areas where stainless inserts resist corrosion - Sealed contact designs with slingers shed splashes while allowing scheduled relubrication - Commonly used in linear slide units, pillow blocks, and flange-mounted conveyor idlers
