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.
Uses cylindrical rollers for line contact, providing higher rigidity and load capacity than ball-type guides.
Equally withstands radial, reverse‑radial, and lateral loads.
Extremely small deformation under heavy load, ensuring stable positioning accuracy.
Larger contact area reduces surface pressure, greatly improving durability and lifespan.
Absorbs minor mounting surface errors and maintains smooth movement.
Multiple seals protect against dust, coolant, and chips, suitable for harsh environments.
Roller structure provides significantly higher rigidity than standard ball-type guides.
Can carry much heavier loads while maintaining precision.
Low vibration, low deflection, and stable motion even under heavy cutting or large loads.
Reduced wear and extended service life under heavy-duty working conditions.
Excellent anti-overturning, anti-pitching, and anti-yaw performance.
Ideal for large machines requiring high stability and precision.
