💡 What is a sealed twin-row roller bearing used for in sheave and pulley systems? They carry heavy radial loads and keep sheaves turning smoothly, handy for lifting and conveyor gear. - Ideal for sheaves, pulleys, hoists, and crane ropes where robust sealed protection is needed - A heavy-duty choice compared to sealed ball bearing or ceramic options for high-load setups - Can complement linear slide unit arrangements when high radial stiffness and sealed duty are required
