| Precision grades P0–P2 (ISO) | Tight tolerances for ultra-precise positioning (±1.5μm repeatability) |
| Vibration classes Z1V1–Z3V3 | Smooth, quiet operation — ideal for medical & lab equipment |
| Grease or oil lubrication | Flexible maintenance; compatible with IP65+ enclosures |
| ISO9001:2008 certified + Taiwan origin | Consistent quality control vs. uncertified mainland alternatives |
| OEM/ODM support & carton/pallet packaging | Fast lead time (<7 days) and custom branding options |
| Applications: Auto, metallurgy, mining, rolling mills | Proven in high-shock, high-dust industrial environments |
Why choose HIWIN HGW over generic linear guides? Higher preload stability, lower friction coefficient (μ = 0.002), and 3× longer fatigue life than standard P5-grade competitors. All units are pre-lubricated, pre-loaded, and tested for running torque & noise before shipment.
FAQ: Q: Are mounting dimensions interchangeable with THK SSR? A: Yes — HGW series follows JIS B 1548-2, fully compatible. Q: Can I use them in vertical axes? A: Absolutely — built-in anti-fall design supports up to 120% dynamic load. Q: What’s the max speed? A: Up to 5 m/s (with proper lubrication & cooling).
