The RGH30HA is an ultra-heavy-duty long-block roller linear carriage designed for industrial applications where maximum load-bearing capacity and vibration damping are non-negotiable. By utilizing an elongated body (L=131.80mm) and cylindrical rollers, the RGH30HA achieves a staggering Static Load Capacity of 105kN, making it one of the most stable components for large-scale CNC machining centers and heavy-duty gantry systems.
Engineered with a high assembly square design, the RGH30HA provides an assembly height of 45mm and a block width of 60mm. This "HA" (High-Square Long) configuration increases the number of contact rollers, which significantly minimizes elastic deformation under massive pressure and ensures ultra-smooth linear motion.
To ensure precise selection for your mechanical design, please refer to the coding logic below:

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.
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: What is the main advantage of using RGH30HA (Long Block) instead of RGH30CA (Standard)? A: The RGH30HA features an elongated carriage (131.80mm) which allows for more cylindrical rollers in the load-bearing zone. This results in a 27% increase in static load capacity (up to 105kN) compared to the standard CA version. It is specifically designed for applications where maximum structural stiffness and vibration damping are required, such as heavy-duty milling.
Q2: Are the mounting hole patterns the same for RGH30CA and RGH30HA? A: No. While they share the same assembly height (45mm) and block width (60mm), the longitudinal hole spacing (C) is different. The RGH30HA uses a 60mm spacing, whereas the standard RGH30CA uses 40mm. Please ensure your base plate is drilled according to the 40 x 60mm pattern before installation.
Q3: Can RGH30HA handle moment loads better than standard blocks? A: Yes, significantly. Due to the longer contact surface and increased number of rollers, the RGH30HA offers much higher moment load ratings (Mr, Mp, My). This makes it ideal for single-rail applications or overhanging loads where preventing tilting or deflection is critical for maintaining precision.
