Products classified under Tariff item 8406.90.29.00
Steam Turbine Bearing Housing
A robust housing unit that encases and supports journal or thrust bearings in steam turbines, maintaining shaft alignment under high loads. It is an essential structural component for turbine operation and is not classified as a rotor, blade, or other specific part listed under sibling tariff items.
8406.90.29Steam Turbine Bellows Expansion Joint
A multi-ply stainless steel bellows expansion joint that compensates for thermal expansion between turbine casing sections. It is a critical component for maintaining alignment in high-temperature environments and is not a rotor, blade, or other specifically listed part.
8406.90.29Steam Turbine Blade Carrier Disc
Forged discs that serve as carriers for turbine blades, providing structural support in high-pressure stages. These are distinct from the blades themselves and are not further advanced beyond their role as carriers, making them 'other parts' of steam turbines.
8406.90.29Steam Turbine Blade Locking Kit
A specialized kit of pins, keys, and rivets used to secure blades to turbine discs against centrifugal forces. Sold as maintenance kits, these are not rotors or blades themselves but are essential for turbine assembly and repair.
8406.90.29Steam Turbine Coupling Shaft
A high-strength forged shaft that connects turbine rotors to generators or loads, transmitting rotational power. It is designed for extreme torque and is not a rotor itself, making it an 'other part' of steam turbines.
8406.90.29Steam Turbine Diaphragm Staging
Stationary diaphragm assemblies with guide vanes that direct steam flow onto turbine blades for optimal energy extraction. These are distinct from rotors or casings and are classified as 'other parts' of steam turbines.
8406.90.29Steam Turbine Emergency Overspeed Governor
A mechanical backup governor that detects rotor overspeed and triggers steam valve closure independently of electronics. It is a safety component, not a rotor or blade, and is classified as an 'other part' of steam turbines.
8406.90.29Steam Turbine Exhaust Casing Section
Low-pressure casing segments that direct exhaust steam to condensers, fabricated from specialized alloys. These are not rotors or blades and are essential for vacuum efficiency in Rankine cycle plants, making them 'other parts' of steam turbines.
8406.90.29Steam Turbine Generator Coupling
A flexible disc or gear-type coupling that synchronizes turbine and generator shafts for grid-stable operation. It is designed for high misalignment tolerance and is not a rotor, making it an 'other part' of steam turbines.
8406.90.29Steam Turbine Nozzle Ring Assembly
A circular array of precision nozzles that accelerate steam into high-velocity jets impinging on turbine blades. It is not a rotor or blade and is classified as an 'other part' of steam turbines, optimizing expansion efficiency.
8406.90.29Steam Turbine Rotor Assembly
A precision-engineered rotor assembly designed for high-speed rotation within steam turbines to convert thermal energy into mechanical power. While it is a rotor, it is not specifically classified under the sibling items for rotors, which cover specific types or stages of advancement, and thus falls under 'other parts'.
8406.90.29Steam Turbine Rotor Support Bracket
Heavy fabricated steel brackets that support turbine rotor assemblies during maintenance or transport. They are not part of the turbine's operational mechanism but are essential for handling, classified as 'other parts' of steam turbines.
8406.90.29Steam Turbine Sealing Gland
A labyrinth or brush-type sealing gland that prevents steam leakage along rotating shafts in turbines. It enhances efficiency and is not a rotor or blade, making it an 'other part' of steam turbines.
8406.90.29Steam Turbine Thrust Bearing
Tilting pad thrust bearings that absorb axial loads from steam pressure differentials on rotors. They are oil-lubricated for continuous operation and are not rotors or blades, classified as 'other parts' of steam turbines.
8406.90.29Steam Turbine Trip Valve Block
Manifold blocks that house emergency trip valves to rapidly cut steam supply for overspeed protection. They are mandatory safety components and are not rotors or blades, classified as 'other parts' of steam turbines.
