Shanghai Beite Technology

A Shanghai auto-chassis parts maker moving into planetary roller screws for humanoid robots.

Shanghai Beite Technology is a Shanghai automotive-parts company listed on the Shanghai Stock Exchange's Main Board (ticker 603009), with core businesses in chassis parts, air-conditioning compressors, and lightweight aluminum components for cars; chassis parts accounted for more than 60% of its roughly RMB 2.3 billion revenue in 2025. Humanoid robots' linear joints commonly use planetary roller screws to convert a motor's rotation into high-force linear motion, a component that demands high machining precision and has long relied on imports. Beite is applying the precision-manufacturing capability it built making auto parts to enter this segment; it reportedly invested about RMB 1.85 billion in 2024 to build screw-manufacturing capacity in Kunshan, Jiangsu, and, according to brokerage research reports, its planetary roller screws have already gone through small-batch trial production and sample shipments with several Chinese humanoid-robot body makers.

ExampleA humanoid robot's knee joint commonly uses a linear actuator — a motor plus a planetary roller screw — to drive the lower leg; the screw itself is the part Beite is targeting.
