RGH Series Roller Type Linear Guide Slider – Introduction & Advantages
The RGH Series is a heavy‑duty, high‑rigidity linear guide that uses cylindrical rollers instead of balls as the motion medium. It is designed for ultra‑high load, high rigidity, and high‑precision applications in heavy machinery and large automation equipment.
Product Features
• Roller-type 4‑point contact structure
Uses cylindrical rollers for line contact, providing higher rigidity and load capacity than ball-type guides.
• Four‑direction equal load capacity
Equally withstands radial, reverse‑radial, and lateral loads.
• High rigidity & low elastic deformation
Extremely small deformation under heavy load, ensuring stable positioning accuracy.
• High load & long service life
Larger contact area reduces surface pressure, greatly improving durability and lifespan.
• Self-aligning capability
Absorbs minor mounting surface errors and maintains smooth movement.
• Dustproof & sealing design
Multiple seals protect against dust, coolant, and chips, suitable for harsh environments.
Core Advantages
1. Ultra-high rigidity
Roller structure provides significantly higher rigidity than standard ball-type guides.
2. Extra heavy load capacity
Can carry much heavier loads while maintaining precision.
3. High running accuracy & stability
Low vibration, low deflection, and stable motion even under heavy cutting or large loads.
4. Long service life & high reliability
Reduced wear and extended service life under heavy-duty working conditions.
5. Strong moment resistance
Excellent anti-overturning, anti-pitching, and anti-yaw performance.
6. Suitable for heavy-duty equipment
Ideal for large machines requiring high stability and precision.
Typical Applications
• CNC machine tools (machining centers, grinders, lathes)
• Heavy-duty automation machinery
• Large-scale positioning systems
• Forging and pressing equipment
• Precision measuring machines
• Laser cutting machines
