Main Technical Parameters and Design
1. Dual Reinforcement Design:
Roller System Reinforcement: Uses large-diameter, high-precision cylindrical rollers and ultra-heavy-duty roller cages to ensure smooth circulation and even force distribution under loads.
Wide Profile Structure Reinforcement: Provides industry-leading guide rail widths (e.g., RGW45, RGW55, RGW65), with a massive slider volume and internal reinforcing rib structure optimized through finite element analysis.
2. Top-Tier Configuration:
Accuracy: Typically only offers top-tier accuracy options such as precision grade (P) and ultra-precision grade (UP).
Preload: Standard configuration is heavy preload (C3) or ultra-heavy preload (C5), achieving excellent rigidity from the factory.
Sealing: Equipped with a fully enclosed multi-seal system and heavy-duty alloy steel scrapers to withstand extremely harsh processing environments.
3. Thermal Management and Installation: The large metal body itself acts as an excellent heat sink, facilitating heat dissipation. Installation requires extremely high demands on the flatness and levelness of the base surface and requires professional adjustment.
Applications
The RGW series exists for ultra-heavy-duty, high-value-added equipment:
Ultra-heavy-duty CNC machine tools: Ultra-large gantry mobile machining centers with widths exceeding 5 meters, heavy-duty nuclear power rotor turning and milling composite machine tools, large ship propeller machining centers.
Heavy industry forming machines: Precision guidance systems for ten-thousand-ton mechanical presses and large die forging presses.
Cutting-edge scientific research and national defense: Large wind tunnel test platforms, satellite assembly and testing equipment, precision motion units for heavy rocket component docking platforms. Energy and Mining Giant Equipment: Large-scale water turbine runner processing equipment, adjustment and positioning mechanisms for giant mining crushers.
The RGW-CC/HC series roller-type wide linear guide rails represent the ultimate form of combining power and precision in linear motion technology. They embody humanity's ambition to push materials, mechanics, and manufacturing processes to their limits in the field of precision mechanical engineering.

Ball Screw Assembly Workshop
We conduct nut assembly in a constant temperature workshop, all workers having decades of work experience and zero clearance between the screw and nut. |
 |
 |
Ball Screw Assembly Workshop
One ball screw shaft matches one ball screw nut. Because each ball screw shaft has a very tiny different tolerance. There are dozens of different ball sizes for different screw shaft. Our ball screw shaft and nut can be interchanged with the Taiwan TBI ball screw shaft and nut very well. |
