The Motorized Pulley (also known as drum motor) is an integrated enclosed drive unit introduced from Denmark’s JOKI company, adhering to international ISO standards and boasting world-class advanced technology. It serves as the core driving device for belt conveyors, directly powering conveyor belt operation with a compact design that integrates motor, reducer, and drum into one. Unlike traditional external drive systems (motor + reducer), this all-in-one structure eliminates complex assembly, reduces space occupation, and enhances operational stability. Widely recognized for its reliable performance, the Motorized Pulley is a preferred choice across multiple industries requiring efficient material handling.
Adopts a direct oil-cooling motor for superior cooling and heat dissipation, enabling smooth transmission even under high temperature rise conditions. The fully enclosed structure ensures good sealing performance, effectively preventing dust, moisture, and mud from entering, making it suitable for harsh working environments.
Features low noise, low energy consumption, and a long service life—key advantages derived from high-quality alloy steel gears and precision-manufactured components. The transmission process is stable with minimal friction, reducing wear and tear and lowering maintenance costs over the product lifecycle.
Offers multiple series (TJ, WD, TDY75, Explosion-Proof, SMROOLL) to meet diverse needs, including explosion-proof requirements for hazardous environments and miniature models for small-scale equipment.
Series | Input Power | Drum Diameter | Drum Width | Belt Speed | Price Range (CNY) |
TJ Series | 0.1kW ~ 90kW | φ110mm ~ φ1000mm | 250mm ~ 2000mm | 0.06m/s ~ 4.25m/s | 3500 ~ 100000 |
WD Series | Customized | φ500mm ~ φ800mm | 500mm ~ 1400mm | 0.5m/s ~ 4m/s | 3500 ~ 100000 |
TDY75 Series | 1.5kW ~ 15kW | φ320mm ~ φ800mm | 500mm ~ 1400mm | 0.8m/s ~ 4m/s | 3500 ~ 100000 |
Explosion-Proof Series | 1.5kW ~ 15kW | φ320mm ~ φ800mm | 500mm ~ 1400mm | 0.8m/s ~ 4m/s | 3500 ~ 100000 |
SMROOLL Series | 1.5kW ~ 7.5kW | φ82mm ~ φ321mm | 270mm ~ 560mm | 0.05m/s ~ 3.2m/s | 300 ~ 20000 |

The Motorized Pulley is widely used in:
Agriculture: Grain conveying and processing lines
Food & Pharmaceutical: Sanitary material handling (compliant with industry hygiene standards)
Mining & Cement: Heavy-duty ore and cement transportation
Tobacco & Automotive: Production line conveying for cigarettes and auto parts
Commerce & Postal Services: Logistics sorting and package handling
Tourism: Escalators and moving walkways
Ensure the drum is horizontally aligned with the conveyor frame to avoid belt deviation.
For large bearings, adopt hot mounting methods (oil bath or electromagnetic induction heating) with temperature not exceeding 120℃.
Tighten all bolts and confirm no gaps between the inner ring and inner seal ring after installation.
Use lithium-based grease for bearing lubrication; fill new/replaced bearings completely and the bearing housing to 2/3 capacity.
Relubricate every half month (adjust based on actual working conditions) via grease gun or centralized lubrication system.
Regularly inspect for pipe damage/blockage in centralized lubrication systems and clean filters periodically.
Factory source with strict quality control, all products pass CE safety certification (SMROOLL series) and ISO standards.
12-month warranty for core components (motor, gears, bearings) against manufacturing defects.
Professional technical support team provides on-site installation guidance and maintenance training.
Spare parts supply with fast delivery to minimize downtime.
Yes. The good sealing performance of TDY75 and Explosion-Proof series prevents moisture and dust ingress, making them ideal for such conditions.
The maximum belt speed reaches 4.25m/s (TJ Series), suitable for high-efficiency conveying needs.
Yes. We offer customized drum diameter, width, and power to match unique application requirements.
