Bore Repairs
Benroc Engineering provide precision on-site bore machining and repair services for industrial and heavy engineering equipment across the UK and internationally.
Common Bore Problems
We repair bores affected by:
- Worn or oversized bearing housings
- Misaligned bores causing operational issues
- Corrosion or pitting in housing surfaces
- Scored, tapered, or blind bores
- Bore surface damage in turbines, gearboxes, or heavy machinery
- Bores requiring face grooves
Our Bore Repair Capabilities
Benroc Engineering delivers precision in-line boring repairs directly on site, avoiding costly removal and transport of heavy components.
Our engineers can machine bores from 30 mm up to 1000mm diameter, restoring worn or damaged surfaces to OEM specifications.
We also offer:
- In-line boring
- Blind bore machining
- Parallel, tapered, and radius bores
- Bore and face grooves
- Sleeving or weld reclamation
- Integration with automatic welding for full bore restoration
This ensures accurate restoration of critical components while minimising operational downtime.
