💡 What is a heavy-duty roller bearing used for in sheave and pulley systems? A solid choice for heavy rotating sheave loads, giving long service under high radial and axial stresses. - Designed to handle high static and dynamic loads in conveyors, hoists, cranes and marine sheaves - Works as an alternative to sealed ball bearing units and can match linear slide unit requirements in heavy rigs - Ideal when inner ring oil holes and shields are needed for relubrication and protection
