Product Details
HIWIN HGW Series Linear Guides – Precision Motion Solutions
| Description | Key Selling Point |
|---|---|
| Models: HGW20HA to HGW65HA | Wide size range for scalable automation & CNC applications |
| Separated rail & block design | Easy installation, maintenance & modular upgrades |
| Single-row, thrust-load optimized | High rigidity & axial load capacity in compact footprint |
| GCr15 bearing steel, hardened & ground | Superior wear resistance & 50,000+ km service life |
| 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 harsh environments — corrosion-resistant surface treatment |
Why choose HIWIN HGW over generic linear guides? Higher dynamic load ratings (+18% avg), tighter preload consistency, and full traceability per batch. Unlike budget brands, every HGW block undergoes 100% noise & torque testing.
FAQ: Q: Are mounting dimensions ISO-standard? A: Yes — fully interchangeable with THK SR/SR-A & Bosch Rexroth KSA series. Q: Can HGW handle vertical loads? A: Yes — with optional dual-side sealing & grease retention. Q: What’s the max speed? A: Up to 5 m/s (with proper lubrication & rail alignment).
