HIWIN HG Series Heavy Load Ball Linear Guide – Single Rail
The HG series is a heavy-load ball linear guide built on a four-row Gothic arch contact design. It carries radial, reverse-radial and lateral loads at the same time, which is why it is the default choice for machine tools, machining centres and heavy gantry structures where rigidity and service life matter more than compactness.
This listing covers the single rail configuration — the guide rail only, with the carriage block ordered separately.
Key features
- HG Series Heavy Load: high load capacity, rated for combined radial, reverse-radial and lateral loads
- Precision-ground raceway with four-row Gothic arch ball contact
- Factory pre-lubricated; re-greasing interval depends on duty cycle and environment
- One series covers several rail widths and lengths, which keeps spare parts simple
Available configurations
| Rail width / size range | 15–65 mm |
|---|---|
| Rail length range | 60–4000 mm |
| Precision grade | C (normal), H (high) |
| Rail fixing method | R (top-mounted) |

Applications
CNC machining centres, heavy gantries, press transfer axes and industrial robots.
Supplied as the guide rail only. Pair it with a matching single block, or choose the complete rail + block set if you want a ready-to-mount axis.
