Zhejiang Huaneng Micro Bearing Co., Ltd. is a leading manufacturer of precision-engineered bearing pulleys built for quiet operation, durability, and long service life. Our range includes advanced screw-thread bearing pulleys that combine the shaft, pulley, and thread into a compact unit—perfect for lifting, positioning, and power transmission in restricted spaces. Each plastic bearing pulley is designed to minimize vibration and ensure smooth movement, using ultrasonic welding for caps and high-performance materials selected for superior strength and wear resistance.
In addition to pulleys, we produce complete door and window roller assemblies, rubber rings, and ball bearings under strict ISO and ABEC quality standards. We offer full customization services—tailored packaging, printed logos, and private color-box designs—to meet diverse client needs. With extensive export experience, Huaneng delivers cost-effective solutions for smart appliances, furniture systems, architectural applications, and industrial conveyors. Free samples are available for testing before bulk orders.
