YF Gear specializes in the design and production of high-precision Timing Belt Pulleys for motion systems requiring zero-slip, accurate synchronization, and low maintenance.
Our pulleys are widely used in robotics, semiconductor machinery, medical imaging systems, and automation equipment, where consistent torque delivery and silence are critical.
We engineer each pulley with optimized groove geometry, ±0.02 mm machining tolerance, and balance correction, ensuring up to 99.8% transmission efficiency even in high-speed, high-load applications.
A Timing Belt Pulley transmits rotational motion through meshing teeth with a toothed belt. Unlike conventional belt drives, this mechanism prevents slippage, maintains constant speed ratio, and supports synchronous motion across multiple shafts.
Our pulleys are manufactured using 6061-T6 anodized aluminum, hardened 40Cr steel, or high-performance PEEK polymer, selected based on specific performance goals—lightweight design, high strength, or low noise.
