Roller Type RGW-CC/HC Series Linear Guideway

The RGW-CC/HC series is a high-assembly, wide-profile roller-type linear guide. Building upon the roller technology of the RGH series, it further increases the width of the guide rail and slider, creating a dual-reinforced structure of "rollers + wide profile." This design aims to provide unparalleled load capacity, anti-overturning moment rigidity, and long-term operational accuracy for "national treasure" level equipment such as ultra-large gantry machine tools, giant floor-type boring machines, and heavy-duty mechanical presses.

Technology

The RGW series is the "ultimate solution" in the heavy-duty field; its performance advantages are a synergistic effect, not simply additive.

Performance Dimensions	RGW-CC/HC Series (Wide-Profile Roller Type)	RGH-CA/HA Series (Standard Roller Type)	HGW-CC/HC Series (Ball Screw, Wide-Profile Type)	Core Values
Core Positioning	The ultimate motion framework for super-heavy-duty equipment, designed to withstand extreme combined loads.	The performance heart of heavy-duty, high-precision machinery.	Heavy-duty general-purpose solution with outstanding performance.	The ultimate solution for extreme operating conditions where standard roller bearings struggle to cope.
Structural Design	Rollers + ultra-wide profile. The combination of two cutting-edge technologies provides the maximum structural cross-section and support area.	Rollers + standard width.	Ball screw + wide profile.	A perfect fusion of physical dimensions and mechanical design.
Load Capacity	Extreme performance. The wide profile significantly increases the effective load-bearing length and number of rollers, achieving top-tier rated load capacities and effortlessly handling loads of hundreds of kilonewtons or more.	Extremely high.	Very high.	Capable of supporting the world’s largest industrial machinery.
Rigidity (Overall)	Unrivalled excellence. Not only is axial rigidity maximised by the rollers, but the wide-profile design also ensures unrivalled rigidity against overturning and torsional loads, resulting in negligible deformation.	Extremely high (axial).	High strength (with emphasis on torque resistance).	Ensures absolute stability of moving components weighing tens of tonnes during high-speed, high-precision motion.
Accuracy Retention	Superior performance. The immense rigidity and the stable reference provided by the wide profile ensure an extremely low rate of precision degradation under long-term heavy loads and impacts, with precision retention far exceeding that of other series throughout the service life.	Outstanding.	Excellent.	Guarantees long-term precision returns on investments in super-large equipment, whilst reducing maintenance costs throughout the entire lifecycle.
Suitable Applications	Super-heavy-duty gantry-type mobile machining centres, large-scale ship component machining equipment, and manufacturing platforms for giant aerospace structural components.	Heavy-duty five-axis machine tools, large-scale precision grinding machines.	Heavy-duty machining centres, large-scale laser cutting platforms.	Serving the nation’s core high-end equipment manufacturing sector

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.
