| 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).
