Bearings for Hydroelectric Facilities
Bearing systems in a hydroelectric facility operate under some of the most demanding conditions found in industrial equipment. They must withstand high static loads for prolonged periods while partially or completely submerged in water. The installation environment frequently exposes bearings to icing, silt, sediment, and erosion — conditions that accelerate corrosive and galvanic action and can quickly degrade lower-quality components.
Adding to the challenge, bearings in hydroelectric applications are often installed in locations that are difficult to access and integrated with massive, mission-critical equipment. This combination makes routine maintenance impractical and, in many cases, cost-prohibitive. As a result, facility operators need bearings engineered to provide trouble-free operation across long service intervals, often measured in years or decades rather than months.
Despite these harsh operating conditions, the bearing must still perform its core function: enabling free, controlled movement of extreme loads at moderate speeds, without binding, excessive wear, or failure.
Engineered for the Demands of Hydroelectric Applications
Lubrite Technologies designs and manufactures bearings for the full range of gate applications found in hydroelectric plants, including spillway gates, intake gates, and control gates. Our bearing solutions are built to resist the corrosion, water exposure, silt infiltration, and heavy static loading that define this environment, helping facilities avoid unplanned downtime and costly equipment repairs.
Beyond gates, many other components within a hydroelectric facility face the same operating challenges and rely on bearings to permit smooth relative motion between two parts. Common applications include:
- Penstock supports
- Sheaves
- Linkages
- Dogging devices
- Floating mooring bits
- Valves
- Lifting mechanisms
Each of these applications carries its own combination of load, speed, submersion, and access constraints. Because of this, off-the-shelf bearing solutions often fall short of what long-term, reliable performance requires.
Custom Engineered Solutions
Every hydroelectric facility presents a unique set of mechanical and environmental conditions, which is why standardized bearing products are rarely the best fit. Lubrite Technologies works directly with engineers and facility operators to design bearings tailored to the specific loads, materials, and environmental exposures of each application. This custom engineering approach helps extend service life, reduce maintenance requirements, and improve overall equipment reliability.

Frequently Asked Questions
What makes hydroelectric bearing applications different from standard industrial bearings? Hydroelectric bearings typically operate under sustained high static loads while submerged or exposed to water, silt, and icing. These conditions promote corrosion and galvanic action that standard bearings are not designed to withstand, making specialized materials and engineering necessary for long-term reliability.
How often do these bearings need to be replaced or serviced? Because many hydroelectric bearing installations are difficult to access, they are engineered for extended service life with minimal maintenance. The specific service interval depends on the application, load conditions, and environmental exposure, which is why Lubrite Technologies evaluates each project individually.
Can Lubrite bearings be used in fully submerged conditions? Yes. Our bearings are engineered to perform reliably whether partially or completely submerged, accounting for water exposure, silt infiltration, and the corrosive conditions common in hydroelectric environments.
What types of hydroelectric equipment use these bearings? In addition to gate systems, bearings are commonly used in penstock supports, sheaves, linkages, dogging devices, floating mooring bits, valves, and lifting mechanisms.
Does Lubrite Technologies offer custom bearing designs, or only standard products? We specialize in custom engineered bearings designed around the specific load, motion, and environmental requirements of each application. Standard products alone often cannot meet the demands of hydroelectric facilities, so our engineering team works closely with clients to develop tailored solutions.
