💡 What is a sealed roller bearing used for in pulley and sheave applications? Sealed roller bearings keep lubricant in and contaminants out, making them handy for pulleys, sheaves and rope-drive setups. - Handles high radial loads and shock in sheave and pulley systems; sealed ball bearing options improve cleanliness and life - Cuts maintenance and contamination risk versus open bearings; useful where ceramic parts or a nearby linear slide unit exist - Commonly used in conveyors, cranes, winches and marine gear when sealed protection, oil holes and high load ratings are needed
