RGR + RGH / RGW Slider Series – Roller Type Heavy-Duty Linear Guideway

The RGH/RGW series is our roller type heavy-duty linear guideway product, paired with RGR series guide rails. Using rollers as rolling elements, it achieves ultra-high rigidity and ultra-heavy load capacity. It follows the widely used RG roller-guide footprint family; roller guides are less standardised than ball guides, so verify all mounting dimensions per size. Suitable for CNC machining centers, heavy-duty cutting machine tools, large gantry equipment, injection molding machines, and other applications requiring ultra-high rigidity and ultra-heavy loads. Offered in standard (CA/CC) and extended (HA/HC) slider types, as well as square (RGH) and flange (RGW) mounting styles.

Key Features

• Assembly Replacement – Direct replacement of existing same-series assemblies (slider + RGR guide rail) in customer equipment
• Roller Rolling Elements – Rollers replace balls, creating line contact between rolling elements and raceways for minimal elastic deformation under load
• Ultra-High Rigidity – Significantly enhanced guideway rigidity to maintain high-precision machining capability
• Ultra-Heavy Load Capacity – Allows selection of smaller guideway sizes compared to ball-type under equivalent load requirements
• Extended Type (HA/HC) – Longer slider body delivers significantly higher dynamic load rating and rigidity than standard type
• Hardened Surface – Guide rails undergo surface hardening treatment for excellent wear resistance and long service life
