Lubron® AQ:
Engineered for Immersed & Water Control Applications.
Lubron AQ self-lubricating bearings are specifically designed for hydroelectric, marine, offshore, and water control applications where continuous exposure to water, high loads, and limited maintenance access demand exceptional reliability. Manufactured from corrosion-resistant bronze alloys and permanently embedded PTFE solid lubricants, Lubron AQ bearings deliver maintenance-free performance in both submerged and dry operating environments.
Developed to withstand long periods of immersion, high water velocities, shock loading, and corrosive environments, Lubron AQ bearings provide dependable low-friction operation and extended service life without the need for oil or grease lubrication.
Applications: Hydro Power & Water Control • Offshore & Marine • Infrastructure • Industrial Equipment • Aerospace & Defense

Why Lubron AQ?
Corrosion Resistant. Water Proven. Maintenance Free.
Lubron AQ bearings combine the low friction properties of PTFE with the strength and rigidity of high-performance bronze alloys to create a bearing system specifically engineered for underwater service. Proprietary solid lubricant technology provides continuous lubrication independent of external grease or oil systems, making Lubron AQ ideal for dam gates, water control structures, and marine equipment.
Unlike graphite-based lubricants that can promote galvanic corrosion in submerged applications, Lubron AQ utilizes specially formulated graphite-free PTFE lubricants developed for long-term immersion and severe water service.
Key Features
-
Engineered for continuous operation in immersed or wet environments, Lubron AQ bearings perform reliably in hydroelectric, water control, and marine applications where conventional lubrication systems are impractical.
-
Embedded PTFE solid lubricants provide continuous low-friction performance without the need for grease or oil, eliminating routine maintenance requirements and reducing operating costs.
-
Manufactured using corrosion-resistant bronze alloys and graphite-free lubricants that resist galvanic attack, pitting, cavitation, erosion, and biofouling in fresh and saltwater environments.
-
Designed to support continuous bearing pressures up to 8,000 psi and short-duration loads up to 15,000 psi, making Lubron AQ suitable for demanding structural and hydraulic applications.
-
PTFE-based lubricant systems provide typical coefficients of friction between 0.02 and 0.10, reducing wear and delivering smooth operation under high loads and slow-speed movement.
-
Advanced AQ100 lubricant technology creates a positive separation between mating surfaces, minimizing wear and extending bearing life even under oscillating motion and prolonged dwell conditions.
-
Performs exceptionally well in reciprocating and oscillating motion where grease circulation is limited and conventional lubricated bearings are prone to wear or seizure.
-
Extreme reliability for hydro dams, navigation locks, water control structures, marine systems, and offshore applications where dependable operation is critical and maintenance access is limited.
Installation:
Lubron AQ bearings are supplied fully machined and ready for installation. Bearings are typically installed using a controlled press fit, with the outside diameter slightly larger than the housing bore to create the required interference fit. Proper running clearances are incorporated into the bearing design to compensate for dimensional changes during installation and ensure optimum performance, alignment, and long-term service life in wet and dry environments.
