Product Description

Industrial automation & transmission precision parts

Industrial automation & transmission precision parts are the core fundamental components that realize motion transmission, power transfer and precise positioning in automated mechanical systems. Covering rotary transmission, linear transmission and connection transmission categories, these parts are widely applied in automated production lines, industrial robots, CNC machine tools, packaging equipment, semiconductor manufacturing, medical devices and new energy equipment.

Manufactured via precision hobbing, grinding, CNC milling and turning processes, our transmission parts achieve dimensional tolerance down to ±0.002 mm and gear accuracy up to ISO Grade 5, ensuring stable, low-noise and long-life operation under high-speed, heavy-load and continuous working conditions. We provide both standard catalog components and fully custom OEM/ODM solutions based on customer drawings, supporting small-batch prototyping and mass production with consistent quality control.
