Bearing Solutions for Mining & Heavy Industry
Heavy-duty hydrodynamic bearings for mills, crushers and large rotating equipment in mining, cement and heavy industrial applications.
Mining and heavy industry operate some of the largest and most heavily loaded rotating equipment in any sector. Bearings in these applications face extreme loads, contamination, and the constant pressure to minimise maintenance downtime.
Applications & Challenges
We support operators and maintenance teams running heavy rotating equipment in demanding environments.
Typical Applications
- Ball mills and SAG mills
- Crushers and grinding equipment
- Cement kilns and kiln drives
- Large gearboxes
- Trunnion bearings
- Heavy-duty fans and blowers
Key Challenges
- Extremely high loads and slow-speed operation
- Contamination from dust, debris and slurry
- Remote locations with limited specialist support
- High cost of downtime in continuous operations
- Large, heavy components requiring specialist handling
What We Provide
