Bearings for Aerospace Applications

Airframe Bearings
– Jet Engine Main Shaft Bearings
The main shaft bearings of a jet engine are critical mechanical components supporting the aircraft’s engine,
essentially the heart of the aircraft.
In order to secure absolute reliability, these bearings are manufactured according to strict process control.

-Jet Engine Gearbox Bearings
Gearboxes mounted with various accessories such as starters and pumps require bearings capable of
maintaining stable performance for long periods of time at high temperatures and high speeds.

– Bearings for Jet Engine Accessories
Bearings are used for rotating parts other than the main shaft and gearbox.
Some examples include the afterburner at the rear of the engine,
the PTO and RDS that connect the engine’s main shaft and gearbox, etc.

– Landing Gear Bearings
Aircraft landing gear bearings are under severe conditions such as sudden acceleration when taking off and
impact load when landing.

– Airframe Bearings
Covering a broad range of uses including private jets and commercial airliners,
EOE has a large lineup of bearings, such as those for flaps and struts (track rollers), movable horizontal tail actuators (thrust bearings),
elevating steering (self-aligning bearings), passenger door locks (track rollers), and air conditioning (combined bearings).

Bearings for Helicopters
– Helicopter Transmission Bearings
Transmission bearings are used to support gears that transmit power from the engine to various areas.
They must be highly reliable as they support the core operations of the helicopter.

– Helicopter Swash Plate Bearings
According to commands from the control stick, the swash plate controls blade pitch angle and movement of the helicopter,
such as buoyancy adjustment and horizontal movement.
The bearings used in swash plates are compact, yet have high capacity.

– Landing Gear Bearings
Aircraft landing gear bearings are under severe conditions such as sudden acceleration when taking off and
impact load when landing.

– Airframe Bearings
Covering a broad range of uses including private jets and commercial airliners,
EOE has a large lineup of bearings, such as those for flaps and struts (track rollers), movable horizontal tail actuators (thrust bearings),
elevating steering (self-aligning bearings), passenger door locks (track rollers), and air conditioning (combined bearings).

Bearings for Devices Used in Outer Space
In the field of space development, EOE offers bearings manufactured by combining special materials technologies and
tribology technology to make them appropriate for use in space where the harsh environment differs from that on Earth,
including factors such as a high vacuum, wide temperature variations and high radiation.
