A cylindrical item in which the inner or outer ring turns upon row(s) of hardened BALL, BEARING which roll on a raceway, thus minimizing friction. These items are characterized by their noncorrosive qualities, lightness of weight, inch dimensions rather than metric, inner rings generally projecting beyond the faces of the outer ring, or a very narrow width inner ring having an outside diameter slightly larger than the bore diameter. Designed primarily for use in aircraft assemblies, such as control systems and surfaces of aircraft. Excludes BEARING, BALL, ANNULAR.

An antifriction bearing having spherical rolling elements designed for use in a track roller assembly.

A cylindrical item in which the inner or outer ring turns upon row(s) of hardened ROLLER, BEARING which roll on a raceway, thus minimizing friction. These items are characterized by their noncorrosive qualities, lightness of weight, inch dimensions rather than metric, inner rings generally projecting beyond the faces of the outer ring, or a very narrow width inner ring having an outside diameter slightly larger than the bore diameter. Designed primarily for use in aircraft assemblies, such as control systems and surfaces of aircraft. Excludes BEARING, ROLLER, CYLINDRICAL.

An antifriction bearing having cylindrical rolling elements designed for use in a track roller assembly.

A special double row ball bearing, retainer type, with integral flange.

A special single or multiple-row ball bearing, rigid or self-aligning, and constructed with either a solid or hollow shank, internally or externally threaded.

A special single or multiple-row roller bearing, rigid or self-aligning, and constructed with either inside threaded, plain hollow, maile threaded, or solid shank.

A single or multiple-row antifriction bearing used with or without inner or outer races characterized by relatively small size rollers usually not ranging above 0.250 inch (6.35mm) diameter and generally longer in length in relation to diameter.

A bearing specifically designed internally to carry the combination radial and axial thrust produced at the end of a tapered or cylindrical flanged shaft in motion. See also BEARING, BALL, THRUST.

A bearing consisting of a ball or roller radial unit and a ball or roller thrust unit. The inner ring of the radial unit is integrally one ring of the thrust unit. See also BEARING, BALL, ANNULAR.

A bearing consisting of a roller radial unit and a roller thrust unit. The inner ring of the radial unit is integrally one ring of the thrust unit. Excludes items in which the same row of rollers accommodates both radial and end thrust.

A special bearing designed primarily to resist axial thrust created by a low speed oscillating steering shaft. See BEARING, BALL, ANNULAR.

A metal or plastic shield located on the face sides of a ball or roller bearing, primarily designed to prevent foreign substances from entering the internal construction of the bearing.

A comparatively flat rigid item, with or without a centrally located aperture, designed to hold an annular bearing or a sleeve bearing in a fitted inclosure. It must have drilled and/or tapped holes for mounting purposes. Excludes END BELL, ELECTRICAL ROTATING EQUIPMENT.

Two single row annular ball bearings selected dimensionally to be a matched pair or set. The ring faces have been specially ground to specified offsets that will produce predetermined preload when mounted. May include a single row angular contact bearing with faces specially ground for duplex mounting.

A multiple assembly of more than two bearings matched for duplex mounting. Designed primarily for aircraft propeller and rotary wing aircraft rotor blade applications. See also BEARING, BALL, ANNULAR.

A multiple assembly of two or more roller bearings designed to evenly accommodate radial thrust. See also BEARING, ROLLER, NEEDLE and BEARING, ROLLER, CYLINDRICAL.

A bearing consisting of either a double row of balls, or a combination of a ball and roller mounted on a shaft having a seal on one or both ends of the outer ring. The shaft has integrally formed raceways for the balls, thereby eliminating the necessity of inner rings. Designed primarily for fan and water pump applications.

A major cylindrical antifriction bearing in which the inner or outer ring turns on a single or multiple row of hardened balls and/or rollers. The rolling elements roll either directly on the inner and outer ring or on race wires inserted into these rings which may have gear teeth. The item is designed for direct eccentric mounting on components requiring support for rotational operation and it is primarily used to accommodate and support radar antennas, gun mounts, tank turrets and slewing cranes.

A set of BALL,BEARING (00036). The balls may belong to a bearing or be used independent from a bearing. In the latter case the function of the inner and outer race is taken over by adjacent components.

A cylindrical device, containing three or more oblong ball circuits complete with a retainer to guide the balls in their proper path, specifically designed for use on sliding linear motion shafts to minimize friction and wear.
