💡 What is a sealed roller bearing used for in industrial linear slide units? Sealed roller bearings keep dirt out and lubrication in, so they run longer under heavy loads. - Provides high radial load support in linear slide units, conveyors, and gearboxes - Often chosen over sealed ball bearings when higher radial capacity is needed in heavy-duty setups - Oil holes and seals reduce maintenance and make relubrication easier for long service life
