Huishi
Qingdao Huishi Transmission Equipment Co., Ltd. has continuously developed and grown into a Premier High-Tech Enterprise in the industrial belt transmission and conveying domain. Operating a modern factory covering over 6,000 square meters, our facility houses 50+ professional engineers, CNC metallurgists, and technical specialists.
Our robust manufacturing ecosystem is powered by over 20 advanced production lines dedicated to transmission belts and conveyor belts, complemented by more than 40 precision mechanical processing instruments (including high-speed CNC gear hobbing machines, automated slotting machines, dynamic balancing testers, and surface anodizing systems). This technical backbone empowers us to meet ultra-tight tolerances required by advanced industrial applications worldwide.
In addition to our flagship proprietary brand BESTLITE, our company maintains high-level strategic partnerships with globally recognized industry giants such as Megadyne (Italy) and Continental (Germany), expanding our product matrix to deliver unparalleled synchronous motion control solutions.
Our operational framework strictly adheres to international quality management norms. We are fully ISO9001:2015 certified, holding over 30 design patents. Recognized officially as a Specialized, Sophisticated, Distinctive, and Innovative Enterprise, Huishi Transmission ensures zero-defect quality control across every production batch.
Synchronous belt drive systems rely on the exact meshing between the pulley teeth and the belt tooth profile. Qingdao Huishi manufactures a complete spectrum of pitch standards configured to international DIN 7721, ISO 5294, and ANSI standards:
Designed with rounded tooth profile geometry to distribute shear stress evenly throughout the belt tooth root. Reduces stress concentration, allows higher torque density, and significantly dampens high-speed acoustic noise.
Engineered specifically for micro-backlash and high-positioning precision. Ideal for closed-loop stepper and servo drives in 3D printers, medical automation, and high-speed robotic pick-and-place arms.
Traditional trapezoidal design featuring high resistance to tooth shear. The AT profile (Advanced Trapezoidal) increases tooth shear area by 30%, maximizing load capability in heavy linear actuation systems.
Choosing the correct alloy substrate and surface treatment determines operational longevity under extreme torque, thermal variation, and corrosive environments.

| Stainless Steel 304 / 316 | 205 - 290 MPa | Electropolishing, Passivation | ISO 2768-fH (±0.01 mm) | Food Processing, Medical Equipment, Marine |
| Engineering Plastic (POM/Delrin) | 65 - 80 MPa | Natural Machined Finish | ISO 2768-mK (±0.05 mm) | Lightweight Conveying, Anti-Static Electronic Lines |
High-speed indexing packaging operations require zero backlash and high dynamic acceleration. Huishi supplies HTD5M and HTD8M timing pulleys coupled with seamless PU belts to deliver synchronous conveyances without skipping tooth engagement during emergency braking cycles.
3D printing gantries and laser engravers rely on lightweight AL6061-T6 GT2 timing wheels. Featuring low rotational inertia and high concentricity (≤0.02mm), these components ensure clean perimeter walls without ghosting or stepping artifacts.
Textile machinery demands continuous multi-axis synchronized drives operating at ambient temperatures up to 80°C. Huishi flat belts and custom timing pulleys withstand lint, dust, and continuous flexing without belt fatigue or pulley rim deformation.
Explosive chemical handling requires non-sparking materials. Our solid stainless steel 316 timing gear pulleys and anti-static polyisoprene belts fulfill stringent ATEX directives for hazardous zone installation.
Quiet operation under 45 dB, maintenance-free continuous duty, and chemical wipe-down tolerance. Cleanroom-compatible polyurethane belts matched with hard-anodized pulleys provide ultra-smooth movement in blood analyzers and automated centrifuges.
V-belt pulleys (SPA, SPB, SPC) with taper-lock cone sleeves provide rapid assembly and immense torque transfer capacities for agricultural combines, heavy crushers, and automotive body assembly transfer systems.
Qingdao Huishi regularly exhibits at international mechanical equipment expos, demonstrating real-time dynamic drive testing and establishing technical OEM relationships across Europe, North America, Southeast Asia, and the Middle East.
Every timing gear pulley and synchronous belt exported by Qingdao Huishi undergoes 100% optical dimension checks and dynamic balancing. We ensure full alignment with global environmental and safety standards:
Huishi Transmission continues to invest over 8% of annual revenue into transmission engineering R&D. Key technical roadmaps for the upcoming decade include:
Over 30 national design patents and ISO9001 quality system certifications demonstrate our commitment to precision engineering.
