Product features:
Zero-Backlash Drive: The teeth mesh tightly with the belt, eliminating backlash during forward and reverse rotation, improving positioning accuracy.
Micron-level Positioning Accuracy: High pitch machining precision ensures a stable transmission ratio even during long-term operation.
Suitable for applications requiring high repeatability, such as CNC machine tools and precision measuring equipment.
The tooth design ensures smooth engagement between the belt and pulley, a constant transmission ratio, and zero speed fluctuation.
This prevents positioning errors caused by slippage, making it suitable for high-frequency starting and braking.
Maintains stable transmission even at high speeds, reducing vibration and noise.
Using CNC precision machining, the tooth pitch accuracy, concentricity, and circular runout meet international standards.
Dynamic balancing ensures zero eccentric vibration even at high speeds.
Each pulley undergoes rigorous dimensional and surface quality inspection to ensure consistent assembly.
Deliver high-precision positioning drives through minimal backlash engagement, engineered specifically for precision positioning systems. Featuring ultra-quiet operation and available in 2mm/3mm/5mm/8mm standard pitch specifications.
