Hydro Turbines

Modern Hydro Turbine Bearing Applications and Support

Kingsbury's line of tilting pad bearings has been the industry standard for more than a century, starting with the first bearing designed and manufactured by Dr. Albert Kingsbury. Kingsbury can supply not only thrust and guide bearings, but the thrust blocks, cooling systems and housings as well.

Hydro-turbine bearing applications typically have relatively low operating speeds and high thrust loads. Depending on the requirements, the thrust bearings may be equalized or non-equalized, and the guide bearings may be fixed geometry or have tilting pads. To date, bearings have been installed on hydro turbines and generators with shaft diameters varying between 150 and 1500 mm.

In addition to supplying bearings for new applications, Kingsbury regularly furnishes retrofits for aging spring plate bearings and other tilting page bearings offering complete diagnostic services, like failure analysis for symptoms like noise and high temperature, wear detection, as well as the replacement or upgrade of other makes of hydrodynamic bearings. Our experienced field service engineers can travel directly to your site to help with dismantling and evaluating larger bearings that are impractical to ship to our factory.

Bearings for Hydro Facilities

Albert Kingsbury invented and installed the original tilting-pad thrust bearing for hydro-electric turbine-generator applications in 1912. Today, Kingsbury remains the global leader in hydro-electric bearing supply, support, and refurbishment.

Installing Insulation Sheet

Kingsbury provides insulated bearings and can convert existing, non-insulated designs into fully insulated bearings to reduce the risk of damage and down-time from stray shaft currents.

Retrofit Thrust/Journal Bearing for Horizontal Hydro Unit

Both traditional vertical and horizontal in-line, or pedestal-mounted bearing designs, are available.

Field Installation of Vertical Hydro Bearing

Expert field installation, shaft alignment, and technical field support are available from Kingsbury.

KBV Self Equalizing Replacement for Aging Thrust Bearing

Kingsbury equalizing vertical thrust bearing replacement of an aging, non-equalizing OEM design. Mechanical leveling plate and pin-style equalization is available. For maximum load equalization and performance, Kingsbury's hydraulically-equalized thrust bearings completely eliminate friction and wear in the support components.

Field Service Inspection of Pumped Storage Unit Thrust Runner

Kingsbury can repair or replace large solid or split thrust runners and thrust blocks up to 144" diameter.
