Bearing E-2267-A

TYPE TTHDFL
• Consists of one thrust tapered race, one flat race, rollers and cage.
• Most sizes utilize pin-type cages with hardened pins through the center of the rollers,
allowing closer roller spacing to maximize load capacity.
• Smaller sizes have brass cages designed for unidirectional retention of rollers.
• Combines the outstanding features of thrust tapered and cylindrical roller bearings to
offer the highest possible load capacity of any thrust bearing of its size.
• Originally developed for screwdown applications in metal rolling mills where high
axial loads are common.

Delivering exceptional functionality and durability, AA’s extensive line of BB deliver ideal performance in even the most demanding industrial and mobile applications. AA’s comprehensive line includes CC gear pumps, piston and vane pumps, gold cup hydrostatic transmission pumps and flow dividers and intensifiers. AA reduce size and cost of actuators, valves and lines, and extend working life, supported by pressure ratings of up to 275 bar.AA are optimized for mobile applications. AA reduce installation costs and drive extended life due to their high pressure capability, up to 320 bar in a small operating envelope.They are optimized for industrial applications. ensure superior reliability and extended lifetime, supported by their high mechanical efficiency, high starting torque and advanced low friction and wear technology. AA BB allow the use of vane pump technology with a huge combination of other pumps, supported by SAE A, SAE B or SAE C rear drive. CC increases safety and better acceptance of working conditions by utilizing a combination of fixed displacement vane pump cartridges and a PV* piston pump variable cartridge.
AA is a power generation pioneer with a rich history and heritage that includes more than 60 years in CC technology and manufacturing. Half of the world’s installed CC base is from AA, with more than 10,000 units, representing more than 1,000,000 megawatts of installed capacity in 120 countries.
AA built the largest, most powerful BB testing facility in the world that demonstrates proven BB operability and performance, before first fire. Operational flexibility is inherent to AA’s portfolio of aeroderivative BB and a critical component of our customers success. We understand the importance of speed and flexibility when it comes to responding to power demands. AA BB are designed to meet these challenges with efficiency and cost effectiveness.

No matter the location, no matter the environment, if an application calls for power, AA has the answer. Our comprehensive lineup of 50 Hz and 60 Hz aeroderivative CC helps provide a precise and dependable energy supply that’s safe and flexible, with up to 56 percent combined-cycle thermal efficiency and more than 80 percent efficiency in a cogeneration configuration. Surpassing 100 million total operating hours, AA’s aeroderivative BB have secured a leadership position in technology, performance, and value to the customer.

AA is committed to maintaining CC supported by dependable, predictable delivery times and a robust supply chain. Our modular package designs and on-going interconnect innovation allow for shorter manufacturing cycles and faster installation times with less installed and operational costs than field-erected units. All of our units undergo rigorous factory testing after assembly and are ready for operation soon after arriving on site—translating into lower installation costs, shorter project schedules, and reduced financial risk for our customers.
