Precision transmission; plastic worm gear

This high-performance plastic worm gear is manufactured from reinforced POM material, featuring excellent wear resistance and a low friction coefficient, specially designed for precision transmission systems The optimized helix angle provides smooth and silent operation, with a torque transmission efficiency of over 92%. The working temperature range is from -30℃ to 8℃, suitable for medical equipment, automotive parts, and smart home devices. Custom services are available for module 0.5-3mm, with three standard colors: black//natural color, a monthly production capacity of 500,000 pieces, and a delivery time of 15-21 working days

    Core Advantages 

    In the field of mechanical transmission, plastic worm gears are gradually replacing traditional metal components. Our products, made with DuPont materials from the United States, achieve dimensional accuracy of ±0.02mm through injection molding. The unique double-ended thread design enhances the load capacity by 40%, and combined with the patented-lubrication technology, it can operate continuously for 10,000 hours without additional lubrication.
