RGH30CA Precision Roller Guide for Grinding Machines

The RGH30CA is a premium high-precision roller linear guide block engineered for heavy-duty industrial applications, specifically optimized for the rigorous stability requirements of grinding machines and high-torque robotic arms. As a pinnacle of the RG series, the RGH30CA utilizes cylindrical rollers as rolling elements, providing a significantly larger contact surface than standard ball guides. This results in an extraordinary Static Load Capacity of 82.1kN, ensuring maximum structural rigidity and vibration damping under extreme pressure.

Designed with a high assembly square configuration, the RGH30CA features a total assembly height of 45mm and a robust block width of 60mm. Its ability to handle a Dynamic Load of 39.1kN while maintaining sub-micron precision makes it the professional choice for high-speed CNC operations and heavy-duty linear motion.

To ensure precise selection for your mechanical design, please refer to the coding logic below:

• RG: Roller Type Linear Guideway Series

• H: High Square Type (Top Mounting Design)

• 30: 28mm Nominal Rail Width

• HA: Heavy Load Capacity (Long Carriage Length)

• ZB: High Preload (Zero Clearance for Maximum Stiffness)

• H: High Precision Grade (G5 Accuracy)

  

• Massive Load Performance: Rated for 39.1kN dynamic load and 82.1kN static load, offering superior safety margins for heavy-duty milling and grinding.

• Extreme Structural Rigidity: The roller-driven system minimizes elastic deformation, providing significantly higher stiffness and damping capacity than conventional ball-type carriages.

• Precision Geometry: Engineered with a 109.80mm block length and a standardized 40 x 40mm mounting hole pattern for ultra-stable integration.

• Seamless Interchangeability: Built to international ISO standards, the RGH30CA is a 100% drop-in replacement for industry-standard 30mm roller series, ensuring zero modifications to your existing CAD designs.

Visual Confirmation: As shown in the high-definition photos above, our RG series maintain rigorous manufacturing standards to ensure seamless integration into your existing systems.

Our RGH30CA is engineered to be 100% dimensionally interchangeable with industry-standard High-Square Standard Block roller guides. It strictly adheres to international ISO standards for mounting hole patterns (40 x 40mm) and the 45mm assembly height.

• Standard Fit: Precision-matched to HIWIN RG30, THK SRG30, and other premium global roller-type linear systems.

• Drop-in Replacement: Direct integration with zero modifications to your existing CAD designs, rail mounting holes, or machine base plates.

• Performance Matched: Specifically designed to provide equivalent damping capacity and stiffness, ensuring seamless maintenance or new project integration.

• 300% Higher Rigidity: The roller-to-rail line contact offers superior structural stability compared to ball-type sliders. This eliminates vibration during heavy-duty milling, directly improving workpiece surface finish.

• Seamless Compatibility: 100% dimensionally interchangeable with HIWIN RG25 series. You can upgrade your machine's performance without modifying existing CAD designs or rail mounting holes.

• Extended Industrial Life: Manufactured from hardened GCr15 bearing steel (HRC 58-62). This ensures exceptional wear resistance and maintains precision even in 24/7 high-intensity manufacturing environments.

• Advanced Dust Protection: Features reinforced double-lip end seals and bottom seals as standard. Effectively prevents metallic debris and coolant ingress, ideal for harsh CNC grinding and milling conditions.

The RGH30CA is specifically recommended for Precision Grinding Machines, heavy-duty bridge mills, and high-torque industrial robotic arms where zero-backlash and long-term wear resistance are critical.

• CNC Machining Centers: The preferred choice for bridge mills, vertical lathes, and gantry milling machines.

• Heavy-Duty Automation: High-load robotic welding cells and heavy-palletizing systems requiring zero-backlash.

• Precision Grinding: Essential for achieving sub-micron surface accuracy through high damping capacity.

• Injection Molding: Robust support for high-load clamping units and precision mold movement.

• Authentic Technical Photos: Every RGH20CA block features professional-grade grinding finish and is treated with high-quality anti-rust oil before vacuum packaging.

• Strict Tolerance Control: 100% full inspection on walking parallelism and preload consistency to meet G5 precision standards.

• Global Logistics: Large inventory maintained for dispatch within 48-72 hours. Supports fast turnaround for urgent maintenance or new project builds.

• Design Support: 3D STEP / CAD files available. Our engineers can assist in cross-referencing models for your BOM optimization.
