| 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).
