Newbee Transmission Powers the Development of China's Commercial Space Industry

Landspace Achieves Another Milestone: Newbee Transmission's Cutting-Edge Bearings Escort the Soaring of Zhuque At 12:12 Beijing Time on May 17, 2025, the improved Yaoter 2 carrier rocket of the Zhuque-2 successfully lifted off from the Dongfeng Commercial Aerospace Innovation Pilot Zone, accurately sending six satellites of the Tianyi Research Institute into their scheduled orbits. This launch came just 24 hours after the previous mission was aborted. Landspace demonstrated its technical confidence through a fully transparent live broadcast, marking a major breakthrough in China's private commercial space industry.

 Hardcore Technical Parameters Rocket Architecture: Two-stage liquid oxygen/methane propulsion configuration Rocket Dimensions: Diameter 3.35m / Overall Height 49.5m Propulsive Performance: Liftoff Weight 219 tons / Thrust 268 tons Fairing: Diameter 4.2m / Length 8.7m Core Innovations:-China's first fully subcooled-loading dual-cryogenic liquid rocket-Niobium-tungsten alloy large-area-ratio nozzle manufacturing technology-Integrated structure of single-layer common-bottom tank and tunnel conveying pipeline Payload Capacity: 4-ton class payload capacity to 500km Sun-synchronous orbit

Newbee Transmission: The "Precision Heart" of Aerospace Power As the core strategic partner of this mission, Newbee Transmission has provided all-round support for the rocket and satellite systems with its aerospace-grade bearing technology:

Rocket Power System-Large-load three-contact ball bearings: Independently developed high-speed bearing sets capable of withstanding extreme conditions of -196°C in liquid oxygen/methane environments

Turbopump low-temperature high-speed bearings: Breakthrough ceramic coating technology enables stable operation at ultra-high speeds of 20,000rpm

Double-half inner ring bearings: Patent-pending split structure eliminates thermal stress deformation, maintaining precision within ±0.001mm

Satellite and Spacecraft Systems-Self-lubricating precision bearings: Vacuum-grade MoS₂ coating technology reduces noise by 20dB, ensuring the space attitude control system-Corrosion-resistant bearing components: Special alloy + plasma nitriding treatment, anti-atomic oxygen erosion life increased by 3 times-Special-shaped drive yoke system: Topology-optimized structure reduces weight by 40%, with a drive efficiency of 98.7%

"Our bearing sets are like the 'power joints' of a rocket," said the Technical Director of Newbee Transmission. "From the millisecond-level response of the engine turbopump to the silent operation of the spacecraft life support system, every link bears the weight of the success or failure of a space mission." China's Acceleration in Commercial Aerospace This successful launch marks the 5th flight mission of Zhuque-2, not only verifying the reliability of liquid oxygen/methane propulsion but also highlighting the mature breakthroughs in China's aerospace supply chain. With enterprises like Newbee Transmission continuously overcoming "necklace" technologies such as high-temperature alloy precision forming and space lubrication, China's commercial aerospace is accelerating the construction of an independent and controllable full-industry-chain ecosystem.

Technical Note: Newbee Transmission's aerospace bearings have passed the NASA-STD-6012 Class C certification, with a service life exceeding 2,000 hours under extreme conditions. They are 15% lighter and 30% more precise than international counterparts.
