The rigidity of the roller-type design is 3 to 5 times higher than that of ball guides, making it highly suitable for heavy-duty CNC machining centers.
Ultra-high load capacity with roller-to-raceway line contact, significantly reducing elastic deformation under heavy cuts.
The 45-degree contact angle design can provide the same load capacity in all four directions (radial, reverse radial and axial).
Optimized roller crowning eliminates stress concentration, ensuring smooth motion and extended service life.
Interchangeable design allows independent replacement of rail or block without losing precision (same-class interchangeability).
High-precision grade options from normal (H) to ultra-precision (UP) to meet various machine tool requirements.
Sealed lubrication system with end seals and grease nipples reduces contamination and maintenance frequency.
Available in two block types - square type (RGH series) for high moment loads and flange type (RGW series) for easy mounting.
Wide rail width range from 25mm to 65mm, suitable for gantry mills, grinders, EDM, injection molding machines, and more.
Proven long service life - roller guide maintains accuracy under high cyclic loads, outperforming ball guides in harsh conditions.
