💡 What are sealed ball bearings used for in linear slide units? Sealed ball bearings keep grease in and grit out, ensuring smooth low-maintenance motion under radial loads. They’re handy for gearboxes, conveyors and automation gear. - sealed ball bearing extends service life by blocking dust and moisture - ideal for linear slide unit rails, conveyor rollers, and small gearboxes - pick steel or ceramic options for higher temperature or lower friction needs
