Recently, Haogrei Technology, an innovator focusing on core components for high end medical imaging, announced the completion of tens of millions of yuan in strategic financing. The round was jointly invested by Anhui Tongchuang Small and Medium sized Sci Tech Transformation Fund Partnership (L.P.), Shenzhen Tongchuang Angel Phase II Private Equity Venture Capital Fund Partnership (L.P.), Huzhou Nanhui Xunying Venture Capital Partnership (L.P.), and Huzhou Nanxun Xunying Venture Capital Partnership (L.P.). The proceeds will be used for large scale mass production and capacity expansion of core products, R&D investment in next generation technology platforms, recruitment of key talents, and construction of global marketing channels.

Previously, Haogrei Technology had secured support from multiple leading institutions including Tongchuang Weiye, Yuanming Capital, and Su Venture Capital, with cumulative financing reaching nearly 100 million yuan. This fully demonstrates capital market confidence in its technical strength and the prospects of domestic substitution for core components in high end medical imaging.
First in China: Haogrei Breaks the Bottleneck of High end CT X ray Tubes
As a core piece of high end medical imaging equipment, CT systems rely heavily on their key component—the X ray tube—which directly determines imaging quality, radiation safety standards, operational stability, and maintenance costs. For a long time, approximately 90% of China’s CT X ray tube market has been monopolized by international giants. This has not only resulted in high procurement prices and long delivery lead times but also created potential supply chain security risks.
Guided by national strategies for domestic substitution and independent control of supply chains, and driven by massive market demand, Haogrei Technology, founded in 2023, takes technological innovation as its core driving force and precisely targets this high barrier, high value core segment, striving to lead the domestic development of CT X ray tubes.
Headquartered in Suzhou National High tech Industrial Development Zone, Haogrei Technology is the first enterprise in China to master core technologies for high power liquid metal bearing X ray tubes. Its founding and core team comprises senior experts from world leading medical device companies, high end vacuum devices, and materials science, with combined expertise in cutting edge R&D, precision manufacturing, and industrialization management.
Since its establishment, Haogrei has focused on the independent R&D and industrialization of liquid metal bearing X ray tubes, accumulating profound practical experience in full chain R&D, precision manufacturing, large scale production, and rigorous verification. Leveraging its strong technological foundation, the company has built end to end independent technical capabilities from raw material R&D to system integration, and successfully developed China’s first liquid metal bearing CT X ray tube platform with independent intellectual property rights. It is committed to overcoming bottlenecks in core CT components, helping achieve self sufficiency in domestic high end X ray tube consumables and CT equipment, and breaking international monopolies.
Breaking International Monopolies: SpaceSpin Sets a New Performance Benchmark for Domestic CT X ray Tubes
Known as the “heart” of a CT system, the X ray tube faces two major technical challenges: enduring extreme heat loads in a confined space, and maintaining long term mechanical stability at tens of thousands of revolutions per minute. Traditional ball bearing tubes suffer from wear, vibration, and failure under high heat and high speeds, creating bottlenecks for tube lifespan and overall CT performance.
Liquid metal bearing technology is widely recognized as the key solution to these pain points, yet the field has long been dominated by international giants. The technical challenges lie mainly in two areas. First, gallium indium tin alloy, which is liquid at room temperature, is highly reactive and tends to react with most metals, weakening grain bonding and causing material pulverization or embrittlement. This process is autocatalytic and accelerates continuously, with enhanced penetration into sealing surfaces especially during high temperature operation. Second, parameters of the liquid metal herringbone spiral bearing—including groove design, helix angle, depth, and clearance ratio—must be precisely controlled; even minor deviations drastically affect lubrication and load capacity.
To address these challenges, Haogrei’s proprietary SpaceSpin Liquid Metal Bearing (LMB) technology replaces steel balls with room temperature liquid gallium indium tin alloy, filling the gap between shaft and sleeve to upgrade from rolling bearings to fluid bearings. This disruptive design delivers three major breakthroughs:
• Thermal conductivity increased by 1,000 times, achieving a leap in bearing heat dissipation;
• Near frictionless sliding drastically reduces vibration, noise, and heat generation;
• Full contact design enables the tube to withstand higher rotational speeds, meeting stringent requirements for high end CT systems of 64 slices and above.
Building on this, the company refined groove geometry, distribution, and hydrodynamic characteristics to maximize load capacity and minimize porosity, successfully resolving core technical challenges in bearing lubrication and load performance.
In terms of operational stability, Haogrei’s self developed high adhesion anti wetting film effectively prevents leakage under cyclic thermal loads of 1,000°C and 75G centrifugal force. Paired with an integrated bearing rotor design, it eliminates leakage risks at the source. For rotational speed limits, the proprietary high load bearing groove passed strict 75G centrifugal testing and stably supports ultra high end CT gantry speeds of 300 RPM. In service life, field verification over 5,000 operating hours confirms a scanning lifespan of up to 1,000,000 seconds, significantly reducing long term operational costs.
Furthermore, Haogrei optimized the X ray tube cathode module for ultra high voltage resistance, providing robust support for high power clinical scenarios. Using uniform cathode field strength technology, the scan interruption arcing rate is minimized, ensuring stable and reliable performance during continuous, high throughput clinical scanning.
From Technical Breakthrough to Ecosystem Building: Haogrei Officially Launches Globalization
Based on this technology platform, Haogrei has launched its first high end CT X ray tube product: Primus 40 Plus.
Equipped with SpaceSpin liquid metal bearing technology and a uniform field strength cathode module, the product ensures stable high speed rotation and ultra long service life even under extreme conditions. Its proprietary SmartID technology delivers industry leading equipment compatibility. Customized high voltage testing and continuous scanning simulations further guarantee exceptional safety and reliability in complex clinical environments.
Primus 40 Plus obtained its medical device registration certificate in late 2025 and has since been installed and put into use in multiple large hospitals nationwide, providing clinicians and patients with more accurate and efficient imaging diagnosis. Haogrei has established strategic partnerships with several well known domestic distributors and maintenance service providers to accelerate clinical adoption across medical institutions.
More importantly, SpaceSpin liquid metal bearing technology is only the first step in Haogrei’s strategic layout, and the launch of Primus 40 Plus carries significance far beyond a single product. The company’s ultimate goal is to evolve from a technological pioneer into a comprehensive solution provider for core medical imaging components.
Following this strategic financing round, Haogrei will focus on large scale mass production in the short term, targeting annual sales revenue exceeding 100 million yuan. It will also deepen cooperation with more mainstream CT system manufacturers and complete R&D and registration of a new generation of high performance X ray tubes.
Looking ahead, the company will consolidate its leading position in the domestic market amid the wave of medical device localization and gradually expand overseas, aiming to become a key global supplier of core CT components. Meanwhile, it will platformize its core technologies and extend into more high end medical device core components such as DSA. Through continuous innovation, Haogrei will participate in and lead the formulation of industry standards, ultimately building a domestic high end medical component ecosystem centered on its own technologies, and delivering more reliable and accessible medical imaging solutions to patients worldwide.
