The HIWIN HGR30 is a linear guide rail system made by HIWIN Technologies Corp., a leading Taiwanese manufacturer known for high-quality motion control products. The HGR30 is part of the HG Series, which is widely used in CNC machines, automation equipment, robotics, and precision manufacturing systems. 🔧 1. What is HIWIN HGR30? HGR30 refers to a 30 mm wide linear guide rail from the HG Series. It works with HGW, HGH, or HGX series carriages (blocks). Provides high load capacity, stiffness, and precision in linear motion systems. 📐 2. Key Specifications Parameter Value Rail Model HGR30 Rail Width 30 mm Mounting Hole Pitch 40 mm (along length) Mounting Hole Size M8 screw Height (rail + block) ~42 mm (depends on block type) Rail Material Hardened carbon steel or stainless steel Precision Grades Normal (N), High (H), Precision (P), Super (SP), Ultra Precision (UP) 🧱 3. Compatible Carriage (Block) Types Block Type Features HGH30 Standard, square-type block (high load, rigidity) HGW30 Wide-type block (better moment load handling) HGX30 Compact-type block (lower profile) HG series blocks use 4 rows of re-circulating balls for high rigidity and load balance. 💡 4. Features of the HGR30 Linear Guide ✅ Four-Row Ball Bearing Design Ensures equal load capacity in all directions (radial, reverse radial, and lateral). High rigidity, ideal for dynamic and static loads. ✅ Self-Aligning Capability Allows the block to compensate for slight misalignments between mounting surfaces. ✅ Interchangeability Rails and blocks can be replaced independently if manufactured to interchangeable specification. ✅ Long Life with High Accuracy Manufactured with hardened raceways and precision grinding. Suitable for long-term, high-speed, and high-precision operation. ⚙️ 5. Technical Performance Dynamic Load Capacity: ~49.3 kN (for HGH30CA block) Static Load Capacity: ~92.3 kN Moment Load Capacities: Mx: ~900 Nm My/Mz: ~890 Nm Operating Speed: Up to 10 m/s (depending on lubrication and preload) Operating Temperature: -10°C to 80°C (standard), higher with special lubrication 🛠️ 6. Applications The HGR30 system is used in: CNC routers, milling machines, lathes 3D printers Robotic arms Automated manufacturing lines Packaging and inspection machines Medical and optical equipment 🧰 7. Mounting and Maintenance Tips Always mount rails on a precision-ground, flat surface. Use preload blocks if you need extra rigidity and less vibration. Use grease nipples on blocks for regular lubrication. Clean surfaces before installation to avoid misalignment or premature wear. 📘 8.
