Product Details
HIWIN HGW Series Linear Guides – Precision Motion Solutions
| Description | Key Selling Point |
|---|---|
| Model Range | HGW20HB to HGW65HB — scalable precision for light to heavy loads |
| Separated Design | Easy installation & maintenance; rail and carriage sold separately |
| Single-Row Thrust Bearing | Optimized for high axial load capacity & smooth bidirectional motion |
| Bearing Steel Construction | Hardened GCr15 steel ensures wear resistance & 50,000+ km service life |
| Precision Grades | P0 to P2 — meets CNC, semiconductor, and metrology-grade positioning needs |
| Vibration Classes | Z1V1–Z3V3 certified — ultra-low noise for cleanroom & medical equipment |
| ISO 9001:2008 Certified | Taiwan-manufactured under strict quality control & traceable batch testing |
| Grease/Oil Lubrication | Pre-lubricated for immediate use; compatible with automated lubrication systems |
| Applications | Automotive assembly, rolling mills, mining conveyors, metallurgy automation |
| SKF-Compatible Mounting | Standardized bolt patterns & dimensions — direct retrofit for SKF LGT/LGR series |
Engineered for reliability where motion accuracy matters — HIWIN HGW guides deliver lower friction (≤0.002μ), 30% higher dynamic load rating, and tighter repeatability vs. generic linear rails. Unlike budget alternatives, every batch undergoes laser-measured straightness verification (<±3μm/m) and surface roughness testing (Ra ≤0.2μm). Ideal for OEMs upgrading from legacy SKF systems seeking seamless integration, longer service intervals, and reduced downtime.
FAQ: Q: Are mounting hardware & grease fittings included? A: Yes — standard kits include stainless fasteners and dual-lube ports. Q: Can HGW45HB replace SKF LGR45? A: Yes — identical footprint, preload options, and ABEC-7 equivalent tolerance. Q: What’s the max operating temperature? A: –10°C to +80°C (grease-optimized).
