About Wuxi Best
Wuxi Best’s established business covers precision-machined automotive components, tooling and intelligent production equipment. Its manufacturing capabilities include high-accuracy machining and process engineering for shafts, housings, impellers and other parts produced at automotive volumes.
Through Yuhua Precision Machinery, the company has expanded into ball screws, roller screws, micro screws and linear guides. Its planetary roller screws are being developed as the core linear-motion element inside humanoid actuators, connecting the group’s precision-manufacturing base with robot joints and other compact electromechanical systems.

- 2026-07-05 - Market Signal - Wuxi Best says humanoid roller-screw samples remain small-revenue business
The abnormal-trading announcement followed a three-day share-price move above the exchange threshold from July 1 to July 3, 2026. Wuxi Best said its humanoid-robot components business was still in the sample stage. It said humanoid-robot planetary roller-screw samples generated CNY 223,000 in first-half 2026 revenue, about 0.03% of total revenue by internal unaudited calculation.

The 2024 annual-report summary says Yuhua Precision products address machine tools, automation, humanoid robots and intelligent connected vehicles. Wuxi Best said ball-screw and linear-guide products were already used in some domestic machine-tool models, with C0-grade ball screws receiving first customer orders. The same disclosure says independently developed planetary roller screws had sampled in 2023 and were still undergoing process optimization and domestic-equipment cooperation.
