Beite Technology Stock (603009): The RMB 1.85 Billion Roller Screw Bet on Humanoid Robots

Shanghai Beite Technology (603009) is a mid-sized Chinese car-parts maker that is spending more than ten years of profit on one humanoid robot component: the planetary roller screw. It is one of the smaller, more speculative names in our Tesla Optimus stocks coverage. Capacity is being built in Kunshan and Thailand, but as of its latest disclosures the screws had no designated customer and no revenue. Here is what investors are actually buying.

Why Roller Screws Matter for Humanoids

A planetary roller screw turns a motor's rotation into straight-line push and pull. Instead of balls, it uses threaded rollers orbiting the screw shaft, which spreads the load over many contact points. That gives high force, stiffness and life in a small package, which is why Tesla and others use roller-screw linear actuators in elbows, hips, knees and ankles. Our Optimus actuator guide shows which joints use them, and the Optimus hardware specs page covers the full robot.

Precision grinding of the threads is the hard part, and the market has long been dominated by European suppliers such as Schaeffler. Chinese companies including Beite are trying to cut costs enough for mass-market humanoids. Actuator assemblers such as Sanhua are the natural buyers, although Tuopu makes its own screws.

The RMB 1.85 Billion Bet

• 2024Beite sets up Jiangsu Beite Robot Technology to develop and commercialize planetary roller screws.
• Oct 2024Announces a RMB 1.85 billion R&D and production base for screws.
• Mar 2025Construction starts at Kunshan; Thailand plant announced with up to $50 million of initial investment.
• Apr 2026Board approves up to RMB 550 million more for Thailand, taking total investment there to about RMB 900 million.
• Jul 31, 2026Shares hit the daily limit-up as humanoid stocks rally; by Aug 18 they are up 37% from the July 30 low.
• Sep 2026Kunshan main structure complete; the Shanghai screw line moves to Kunshan.

For scale: Beite earned about RMB 120 million in all of 2025, per Huxiu. The screw program alone is roughly 15 times that annual profit.

Kunshan and Thailand: The Build-Out

Figures from Hualong Securities (October 2026) and Huxiu. The Thailand site matters because a non-China plant lets Beite sell into US supply chains with less tariff and export-control risk. Hualong says the screw range includes planetary roller, ball and trapezoidal screws, including micro screws for dexterous hands, plus automotive uses such as rear-wheel steering and brake-by-wire. That car demand gives the new plants a fallback if humanoid volumes are slow.

Customers: Still at the Sample Stage

Tesla began auditing Chinese Optimus suppliers in September 2026, according to reports including CnEVPost, and Chinese social media has linked Beite to that process. We found no credible report that Beite passed a Tesla audit or won an Optimus order. Treat any such claim as unconfirmed.

The Car-Parts Business Pays the Bills

The October 27 report showed revenue growth speeding up from 8.4% in Q2. Gross margin slipped on customer price cuts and raw-material costs. In 2025, chassis parts brought in RMB 1.43 billion, while compressors (+36%) and aluminum lightweighting (+50%) grew fastest. It is a steady but low-margin business that has to fund the screw build-out.

Valuation: Paying Before Revenue

Hualong forecasts net profit of RMB 157 million in 2026, RMB 245 million in 2027 and RMB 415 million in 2028, which it says equals 117, 75 and 44 times earnings at the late-October price. A car-parts company growing 10% a year would normally trade far lower; our estimate is that most of the market value now rests on the screw business succeeding. Key risks: no designated customer yet, heavy capital spending that could pressure cash flow, competition from established screw makers and dozens of new Chinese entrants, and the timing of humanoid mass production.

The Bottom Line

Beite Technology is a pure capacity bet: a profitable but modest car-parts maker building 3.4 million sets of annual roller screw capacity before it has a named customer. Its Q3 2026 results were steady, and the Kunshan and Thailand plants should start in 2026. The stock will be decided by one event that has not happened yet: a confirmed volume order from a humanoid maker. Until then, it is one of the most speculative names in the Optimus supply chain.
