Key Performance Advantages
Precision Ground Tooth Profile
All teeth are ground after heat treatment to ensure:
• Minimal pitch deviation
• Stable gear meshing
• Consistent transmission accuracy in long-term operation
Hardened Surface for Industrial Durability: Surface hardness reaches HRC 50–60, ensuring strong wear resistance in continuous motion systems.
Low Backlash Precision Control: Manufactured under strict tolerance control for stable positioning performance.
High Load Capacity Design: Optimized gear geometry supports heavy-duty industrial applications without deformation.
Smooth & Low Noise Operation: Improved tooth contact reduces vibration and operating noise in high-speed systems.
Application Engineering Scope
Our racks are purpose-built for seamless integration into real-world, high-duty industrial motion systems:
CNC Gantry Machining Centers: X, Y, and Z-axis high-speed linear drive systems.
Fiber Laser Cutting Systems: High-acceleration gantry motion modules.
Automated Storage & Retrieval Systems (AS/RS): Heavy-duty travel axes for logistics shuttles.
Robotic Linear Transfer Tracks (7th Axis): Extending the work envelope of industrial articulated robots.
High-Speed Packaging & Printing Lines: Continuous, low-maintenance precise indexing.
Engineering Selection Guide
Maximize your system's lifespan and dynamic performance by selecting the correct specification:
M1 – M3: Optimized for light automation, medical equipment, and precise lab positioning platforms.
M4 – M6: Designed for CNC gantry machining centers, fiber laser cutting machines, and robotic tracks.
M6 – M12: Engineered for heavy-duty industrial cranes, heavy material handling, and structural steel automation.
Straight Rack: Ideal for standard linear positioning, cost-effective setups, and lower-speed indexing.
Helical Rack: Best for high-speed (>2m/s), low-noise, high-axial-thrust, and ultra-smooth motion profiles.
