What Challenges Do Your Equipment and Procurement Teams Face?
Industry-specific pain points and how Yantong Tech addresses them
Packaging Machinery
Noise and backlash in high-frequency start-stop cycles affect filling precision and operator comfort.
Yantong provides precision-matched worm gear sets with controlled backlash and surface finish, ensuring smooth operation and low noise over extended duty cycles.
Wind Power Equipment
Yaw and pitch systems demand high reliability in harsh environments; unexpected failures lead to costly downtime and difficult maintenance access.
Yantong supplies planetary and internal gears with validated heat treatment and documented tooth profile accuracy, designed to withstand continuous load and environmental stress.
Mining & Heavy Equipment
Large girth gears in rotary kilns and ball mills face high shock loads and require maintainable, long-life components to minimize production interruptions.
Yantong offers girth gears and internal gears with controlled case depth and surface integrity, supported by full material traceability and NDT reports for predictable service life.
