💡 What is a roller bearing used for in linear slide unit and heavy-duty shaft applications? Roller bearings support radial loads and keep shafts tracking smoothly under heavy load. Short intro: They provide strong radial support, alignment, and serviceability for industrial motion systems. - Ideal for linear slide unit guides, conveyor rollers, and heavy-duty shaft supports - Open oil-hole design allows periodic relubrication versus sealed ball bearing alternatives - Common choice where ceramic options aren't needed and metal high-carbon steel strength is handy
