From Precision Bearings to Intelligent Motion Technology — The Evolution of Wuxi Sanli

Strategic Upgrade Toward Intelligent Manufacturing

As China’s manufacturing industry continues advancing toward high-precision and intelligent production, the bearing sector is also evolving from conventional manufacturing toward precision engineering and intelligent motion technologies.

Against this industry backdrop, Wuxi Sanli Bearing Co., Ltd. has officially upgraded to Wuxi Sanli Robot Technology Co., Ltd. following a strategic partnership with JCHX Interconnect.

The transition reflects the company’s long-term expansion into:

  • Precision motion systems

  • Industrial robotics components

  • Intelligent transmission technologies

  • High-performance bearing applications

Rather than representing a simple company rebranding, the move signals a broader shift toward advanced manufacturing, robotics integration, and precision industrial applications.

Strategic Cooperation with JCHX Interconnect (Fengdong Heat Treatment)

JCHX Interconnect originates from Fengdong Heat Treatment, one of China’s established companies specializing in industrial heat treatment equipment and thermal processing technologies.

With decades of experience in heat treatment systems, material engineering, industrial furnace technologies, and precision thermal processing, Fengdong has developed strong technical capabilities within the heat treatment industry.
