High Torque 113mm Oil-Cooled Motorized Pulley Drum Motor for Belt Conveyors - China Suppliers & Factory
The 113mm oil-cooled motorized pulley drum motor is engineered for belt conveyor systems that require high torque, compact structure, and low noise operation. Designed with advanced manufacturing techniques, the DM113i features precision-ground high-alloy steel gears and high-accuracy assembly. This ensures smooth transmission, reduced vibration, and stable performance in demanding industrial environments.
The oil-immersed cooling design improves heat dissipation and extends motor life. With built-in thermal protection and F-class insulation, the motor operates safely even under continuous load conditions. The compact drum motor design eliminates external drive components, reducing installation space and maintenance requirements.
The DM113i motorized pulley supports global voltage compatibility at 50Hz and 60Hz frequencies. It also offers flexible customization options, including adjustable belt speed, drum length, and optional backstop installation. The sealed structure with IP67 protection allows operation in dusty, humid, or washdown environments.
The drum shell is available in carbon steel or food-grade 304 stainless steel, making it suitable for both industrial and hygienic applications. Anti-slip surface machining further improves belt traction and operational stability.
The 113mm motorized pulley is widely used in airport conveyors, packaging systems, food processing, pharmaceutical handling, and modular belt applications. Its durable design and low maintenance requirements make it an ideal solution for modern conveyor systems.
