GGB. Leading the way in hydropower bearings.

These days, the growing global demand for hydropower is ever increasing. GGB has extensive experience and expertise in the hydropower industry. Our HPF™, HPM™ and DB™ bearings were designed specifically for use in turbine wicket gates, operating ring axial and radial bearings and valves. These bearings provide a number of benefits including:

Thinner walls and shorter lengths for significant savings in new builds.

Flexibility for easy replacement of laminate fiber or bronze bearings in existing designs, so they do not require additional lubricants that can contaminate rivers.

Corrosion resistance and self-lubrication which cuts back on man-hours and environmental impact.

Both HPF and HPM bearings meet hydropower industry standards for turbine wicket gate applications per independent tests conducted by Powertech Labs.
