💡 Why choose roller bearings instead of sealed ball bearings for heavy radial loads? A roller bearing handles heavy radial forces better than a sealed ball bearing in many industrial setups. - Higher contact area gives better load distribution for heavy radial and shock loads - Works well in linear slide unit and conveyor systems where rigidity matters - Oil holes and an open design let you re-lube under load for longer service life - Ceramic balls are great for speed or corrosion needs, but rollers win on radial capacity
