XULONG pushes micro-scale linear motion into smart manufacturing

By AI, Created 4:55 AM UTC, May 22, 2026, /AGP/ – Dwxin-Xulong, also known as XULONG Technology, says it has begun mass production of 2mm and 3mm linear guide rails, a capability aimed at precision equipment makers across semiconductors, medical devices and robotics. The move highlights how Chinese manufacturers are using miniaturization and integrated motion systems to compete in high-end industrial hardware.

Why it matters: - Micro-scale linear guide rails are becoming essential as factories, labs and robot builders shrink equipment while demanding higher precision. - XULONG’s ability to mass-produce 2mm and 3mm specifications puts pressure on a segment that has traditionally been limited to a small number of global tier-one suppliers. - The company is targeting applications where size, repeatability and low noise directly affect equipment performance and service life.

What happened: - Dwxin-Xulong, a Dongguan-based manufacturer founded in 2014, said it has reached mass production of ultra-small 2mm and 3mm linear guide rails. - The company markets its DV series in two main configurations: DVN standard and DVW wide. - The portfolio spans 10 series and 48 models from 2mm to 20mm. - XULONG says its official website is the company’s announcement.

The details: - The guideways use a Gothic four-point contact design for equal load capacity in four directions. - The components are made in alloy steel and stainless steel versions. - Integrated ball retainers are designed to support smooth, low-noise operation. - Rail and block interchangeability is built in to simplify maintenance. - XULONG offers three accuracy grades: N, H and P. - The top P-grade claims running parallelism of ±0.005mm/m. - Surface roughness is listed at Ra≤0.2μm. - The company says these specs reduce friction and thermal expansion and support long-term stability. - In semiconductor and electronics assembly, the 2mm to 5mm series is aimed at wafer handling, IC packaging and inspection equipment. - The smallest rails can weigh less than 50g per rail in lightweight designs. - In 3C manufacturing, demand is being driven by foldable screen hinges and camera modules. - In medical instrumentation, a single in-vitro diagnostic device may use up to 12 DVN7 or DVN9 rails to reach ±0.01mm positioning accuracy. - Stainless steel rails with ceramic bearings are positioned for 3D scanning water tanks and other liquid-exposure applications. - In robotics, the rails are used in collaborative robot joints and end-effectors for frequent start-stop cycles and low-noise motion. - In photovoltaic and lithium battery equipment, the components support long-stroke, low-energy transport during testing and assembly. - XULONG says it has four micro-guideway production lines and four block production lines. - The company lists annual capacity at 800,000 precision guideway sets and 500,000 sliding tables. - XULONG says its production scale lets it offer performance similar to top-tier global brands at a cost structure 20% to 30% more efficient. - The company says its quality system includes ISO 9001, ISO 14001 and ISO 45001 certifications. - XULONG also cites 21 utility and design patents.

Between the lines: - The release frames XULONG as moving from parts supplier to systems partner, with a focus on matching guideways, servo motors, planetary gearboxes and precision couplings. - That integrated approach is meant to reduce vibration and mechanical resonance in compact equipment. - The emphasis on vertical integration suggests the company is competing on both capability and price, not just on technical specifications.

What’s next: - XULONG says it plans to expand its global footprint and deepen its technology advantages. - The company is betting that demand for smaller, more precise motion systems will keep rising as smart manufacturing spreads. - Future growth will likely depend on how quickly customers adopt micro-guideways in next-generation automation, medical and energy equipment.
