What is an Annular Ball Bearing?

An Annular Ball Bearing (BEARING,BALL,ANNULAR) is a cylindrical device in which the inner or outer ring turns upon a single or double row of hardened balls which roll easily between the two rings, thus minimizing friction. For items with faces specially ground for duplex mounting see BEARING, BALL, DUPLEX. Excludes BEARING, BALL, AIRFRAME.

What is a Cylindrical Roller Bearing?

A Cylindrical Roller Bearing (BEARING,ROLLER,CYLINDRICAL) is a nonadjustable roller bearing consisting of a single or multiple-row of hardened cylindrical rollers and a retainer used with or without inner or oute r rings. Excludes BEARING, ROLLER, AIRFRAME.

What is a Self-Aligning Roller Bearing?

A Self-Aligning Roller Bearing (BEARING,ROLLER,SELF-ALIGNING) is an antifriction bearing having a cylindrical rolling element and one spherical raceway which will adjust to varying degrees of shaft and/or support misalignment without damage to the raceways and permits the full rating of the bearing to be utilized.

What is a Thrust Ball Bearing?

A Thrust Ball Bearing (BEARING,BALL,THRUST) is an antifriction bearing having a ball rolling element, designed to resist axial thrust, or to support an axial load. Excludes BEARING, BALL, PIVOT.

What is a Tapered Roller Bearing?

A Tapered Roller Bearing (BEARING,ROLLER,TAPERED) is a cylindrical device in which the inner cone or outer cup turns upon a single or double row of tapered hardened rollers which roll easily in a race, thus minimizing friction and designed to carry a radial load and capable of sustaining axial thrust. Excludes BEARING, ROLLER, THRUST.

What is an Inner Bearing Ring?

An Inner Bearing Ring (RING,BEARING,INNER) is the inner component of a ball or roller bearing which provides a contact surface for the rolling elements of an antifriction bearing.

What is a Bearing Retainer And Rollers?

A Bearing Retainer And Rollers (RETAINER AND ROLLERS,BEARING) is an assembled inner component of a roller bearing, consisting of a frame or inclosure which spaces and retains the rolling elements of a BEARING, ROLLER (as modified) and the rollers which are the rolling elements in a BEARING, ROLLER (as modified).

What is a Bearing Ball?

A Bearing Ball (BALL,BEARING) is a homogenous spherical body, a series of which provides the rolling elements in a BEARING, BALL (as modified). The item is designed primarily to alleviate friction. It may have other usages such as the checking component in a ball-type check valve. Excludes BALL, CHECK; BALL, VALVE, PORTED.

What is a Bearing Roller?

A Bearing Roller (ROLLER,BEARING) is a cylindrical body of either solid or hollow construction which provides the rolling elements in the roller bearing.

What is an Airframe Ball Bearing?

An Airframe Ball Bearing (BEARING,BALL,AIRFRAME) is 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.

What is an Airframe Roller Bearing?

An Airframe Roller Bearing (BEARING,ROLLER,AIRFRAME) is 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.

What is a Needle Roller Bearing?

A Needle Roller Bearing (BEARING,ROLLER,NEEDLE) is 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.

What is a Mechanical Equipment Bearing Replacement Parts Kit?

A Mechanical Equipment Bearing Replacement Parts Kit (PARTS KIT,BEARING REPLACEMENT,MECHANICAL EQUIPMENT) is a parts kit consisting of one or more bearings or bearing assemblies, which are issued as a unit for repair/replacement. It may include gasket(s), O-ring(s), race(s), seal(s), spacer(s), washer(s), or the like.

NATO Supply Class 3110 refers to Bearings, Antifriction, Unmounted. This class is a part of NATO Supply Group 31, which is specifically dedicated to Bearings.

Bearings are mechanical components that are used to reduce friction between moving parts and support rotational or linear motion. They are crucial in various industries, including automotive, aerospace, industrial machinery, and more.

The NATO Supply Class 3110 includes antifriction bearings that are unmounted. Antifriction bearings are designed to minimize friction and provide smooth operation by utilizing rolling elements, such as balls or rollers, between the bearing races.

These unmounted bearings are typically purchased separately and then installed into a housing or assembly as required. They come in various types, such as ball bearings, roller bearings, and needle bearings, each suitable for different applications and load capacities.

NATO Supply Class 3110 for Bearings, Antifriction, Unmounted plays a vital role in ensuring the availability of high-quality bearings for military and defense purposes within the NATO supply system.

If you need more specific information about a particular type of bearing or any other details related to NATO Supply Class 3110, please let me know.
