💡 What is a roller bearing used for in a linear slide unit and other heavy-load setups? Roller bearings guide rotational or linear motion while handling radial loads and shock. - Ideal for linear slide units, shaft supports, gearboxes, and conveyor applications - Full-complement rollers give higher static capacity for heavy-load, low-speed duty - Sealed ball bearing options help contamination control; ceramic choices lower friction - Check ID/OD/width (17×30×13 mm) to match housing or adapter for best life
