💡 What is a sealed roller bearing used for in sheave and pulley systems and why pick one over a sealed ball bearing? Sealed roller bearings are built to handle higher radial loads and shock in rotating sheave and pulley setups, so they are handy for heavy lifting and continuous-duty conveyor runs. Quick take: - Handles heavier radial loads than typical sealed ball bearings, ideal for large sheaves and pulleys - Works well in pulley, winch and crane assemblies and can suit certain linear slide unit setups - Inner-ring oil holes allow relubrication to extend service life and reduce downtime - Choose sealed high-carbon steel bearings when operating temperatures reach up to 120 deg C
