Aircraft Bearing

Share |

Every bearing used in an aircraft is considered important. Aircraft bearings are precision bearings that range from miniature bearings to spherical bearings. These bearings are used in wheels, seats, controls carriages and flight instruments etc.

The aircraft bearings need to comply with certain standards like high precision angular contact, they need to be separable type. They need to have plain lined or unlined bushings and sleeves. These and many other standards need to be maintained for safety reasons. General precision aerospace bearings normally take the form of deep groove or cylindrical roller bearings and are used in hydraulic and engine/APU applications.

Ball bearing types are used extensively throughout aircraft airframe and engine design. They are the most versatile and well engineered.
Amongst roller bearings, cylindrical roller bearings, taper roller bearings or certain specialist roller devices are used for different applications.
Cylindrical roller bearings are found in pumps, engines, engine gearboxes or auxiliary power units. They are all suitable for medium speed applications.
Taper roller bearings are most commonly used in wheel applications for all aircraft. Their ability to take radial and axial loads is unmatched.
Aircraft door mechanism, undercarriage, flaps and slats are places where roller bearings are used.
Needle roller bearings for aircraft are found in the wings, on the slat and flap carriages. Their ability to support high vibratory loads and is rather compact.
