💡 What is a needle roller bearing used for in industrial linear slide units and heavy machinery? They handle high radial loads in tight spaces and are handy where compact design matters. - Commonly used in linear slide units, gearboxes, transmissions, and cam followers to save space and add load capacity - Provide higher radial capacity than sealed ball bearing options in narrow housings and shafts - Available with oil holes and caged designs for easier maintenance; ceramic options exist for specific high-speed or low-friction needs
