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.

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.
Q1: Can I replace a standard HGH30 ball-type block with an RGH30CA roller block?
A: Dimensionally, yes—both have an assembly height of 45mm and a 40x40mm mounting pattern. However, RGH30CA roller blocks must be used with RGR30 roller rails. You cannot install a roller block on a ball-type rail (HGR30) because the internal raceway geometry is different. Upgrading to a roller system will significantly improve the rigidity of your machine.
Q2: How does the 82.1kN static load capacity of RGH30CA benefit my grinding machine?
A: In grinding applications, high static load capacity (C0) is critical for absorbing vibration and resisting "chatter" during heavy-duty cutting. The 82.1kN rating of the RGH30CA ensures that the carriage maintains sub-micron contact stability, directly resulting in a superior surface finish on your workpieces compared to standard ball-type guides.
Q3: Is the RGH30CA compatible with automatic lubrication systems?
A: Yes. The RGH30CA comes standard with high-quality end seals and is designed with grease nipples that can be integrated into centralized lubrication systems. Given its heavy-duty rating (39.1kN dynamic load), we recommend regular lubrication intervals to maintain the precision of the cylindrical rollers in high-duty cycle environments
