Babbit Thrust Tilting Pad Bearing for Turbine and Marine

Marine Propulsion Thrust System

White metal bearings are critical components in marine thrust propulsion shaft and intermediate shaft. Their soft matrix can embed sand and particles, preventing propulsion shaft journal scoring. The self-lubricating structure continuously forms an oil film during oil circulation, ensuring low-friction operation between the intermediate shaft and sliding babbitt bearing. In inland waterway shipping (e.g., Yangtze River, Yellow River), babbitt tunnel bearings reduce wear through embeddability and prevent sudden failures through anti-seizure properties, ensuring long-term vessel operation. Even during brief lubricant interruptions, the micro-oil-reservoir structure maintains protection, adapting to harsh conditions. As the key to reliable marine shaft system operation, they offer far longer service life than other materials, reducing maintenance downtime and costs.

Heavy-Duty Mining Equipment

White metal bearings serve as the core support for low-speed, heavy-load equipment such as ball mills,vertical roller mill and rolling mills in mining. These machines experience frequent starts/stops and high impact loads, requiring plain bush babbitt bearings to withstand extreme conditions. The hard-particle-in-soft-matrix design of white metal provides both anti-seizure and embeddability—absorbing vibration, embedding metallic debris, and avoiding journal damage. Self-lubricating properties reduce dependence on lubrication systems and lower maintenance frequency. In harsh, dusty environments, the stable friction coefficient and wear resistance ensure continuous operation, extend component life, and reduce production line downtime risks from bearing failure, forming the foundation of reliable heavy industry operations.

Water Turbines

White metal bearings provide critical support for water turbines in hydropower stations. Turbines operate continuously for long periods with slight shaft deflections, requiring tilting pad babbitt bearings to balance load capacity with flexibility. The soft matrix of white metal self-adapts to journal deformation, embeds micro-particles, and prevents abrasive wear. The self-lubricating structure maintains a stable oil film even at low speeds, reducing vibration and heat generation. Low friction coefficient ensures unit efficiency, while anti-seizure properties prevent sudden shutdowns. In large hydropower stations like the Three Gorges Dam, white metal thrust pad bearings deliver decades of reliable power generation, becoming indispensable components in the clean energy sector by balancing rigidity with adaptability.

Steam Turbines

Turbine journal tilting pad bearings are key foundational components in the steam turbine industry. Through their excellent friction reduction, corrosion resistance, and reliability, they ensure stable operation of steam turbines under severe conditions. Looking ahead, with advances in materials science and lubrication technology, Turbine Rotor Thrust babbitt bearings will continue to be optimized, while new material technologies will also provide additional options for steam turbine Radial Thrust pad Din bearings.
