In the case of a double bearings roller, it typically refers to a pulley system that incorporates two roller bearings to support the sheave. Roller bearings are designed to reduce friction and provide smooth rotation, allowing the pulley to operate efficiently. By using double roller bearings, the pulley can handle heavier loads and provide increased stability and durability.

The double bearings roller configuration is commonly found in various lifting applications, such as cranes, hoists, block and tackle systems, and other machinery where heavy loads need to be moved vertically or horizontally. The use of double roller bearings helps distribute the load evenly and reduces strain on individual bearings, ensuring reliable and efficient operation of the pulley system.
