NATO Supply Class 3120 refers to Bearings, Plain, 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 commonly used in various industries such as automotive, aerospace, machinery, and more.

The NATO Supply Class 3120 includes plain bearings that are unmounted. Plain bearings, also known as sleeve bearings or bushings, are the simplest type of bearings. They consist of a cylindrical sleeve made of a low-friction material, such as bronze or plastic, which provides a smooth surface for the rotating shaft to slide against.

These unmounted plain bearings are typically used in applications where the shaft is stationary, and the bearing is mounted in a housing or support structure. They are designed to handle radial loads, which are forces acting perpendicular to the shaft's axis.

NATO Supply Class 3120 for Bearings, Plain, Unmounted encompasses a wide range of sizes, materials, and designs to accommodate different applications and operating conditions. It is important to select the appropriate bearing based on factors such as load capacity, speed, temperature, and environmental conditions.

When procuring bearings within this NATO Supply Class, it is essential to ensure compliance with NATO standards and specifications to maintain interoperability and compatibility within the NATO supply chain.

Overall, NATO Supply Class 3120 for Bearings, Plain, Unmounted plays a crucial role in the NATO Supply Group 31 for Bearings, providing the necessary components for various mechanical systems and equipment.

FSC 3120 Bearings, Plain, Unmounted - Korea (KR)
FSC 3120 Bearings, Plain, Unmounted - Korea (KR)

Includes Sleeve Bearings; Split Bearings; Washer Type Bearings; Jewel Bearings.

Excludes Antifriction Bearings (FSC 3110); Mounted Bearings (FSC 3130).

Note-All bearings, including specially designed, lubricated, and/or selected, are to be classified in the appropriate classes of this group. Bearings are parts that supports another part which rotates, slides, or oscillates in or on it.

Supply Items Included in Federal Supply Class 3120 Supply Items Included in Federal Supply Class 3120

What is a Spherical Plain Bearing? 71 Items
A Spherical Plain Bearing (BEARING,PLAIN,SPHERICAL) is a detachable part in or on which a journal, gudgeon, pivot, or the like moves. It is used to carry a load and to reduce sliding friction. It does not employ rolling elements. It may be divided into two or more segments of 180 degrees (3.141 radians) or less. The item has a cylindrical bore and is basically spherical in its exterior design to allow for shaft misalignment. Excludes BEARING, PLAIN, SELF-ALIGNING.
What is a Sleeve Bearing? 111 Items
A Sleeve Bearing (BEARING,SLEEVE) is a tubular shaped item with or without flange(s) designed to reduce friction and carry a kinetic load on the surface(s) parallel to the axis of the bore. It must have a visible or detectable means of lubrication or be self-lubricated. The over all length must exceed 25 percent of the outside diameter or the shortest distance between peripheral flats of the body, except for straight tubular (without flange or shoulder) items having a bearing surface(s) parallel to the axis of the bore only. Includes items which are divided into two or more segments which include 180 degrees (3.141 radians) or less of the bearing periphery. See also BUSHING, SLEEVE; SPACER, SLEEVE; and WASHER (as modified). Excludes PIN, HOLLOW.
What is a Sleeve Bushing? 550 Items
A Sleeve Bushing (BUSHING,SLEEVE) is a tubular shaped unthreaded item with or without a flange at one end designed to be inserted into a hole to reduce the inside diameter of the hole and to protect the surrounding body structure from damage resulting from stress, strain, and/or vibration. The overall length must exceed 25 percent of the outside diameter or the shortest distance between peripheral flats of the body. Includes items which are divided into two or more segments which includes 180 degrees (3.141 radians) or less of the bearing periphery. For items made of rubber, see BUSHING, NONMETALLIC. See also BEARING, SLEEVE; BUSHING, TAPERED; SPACER, SLEEVE; INSULATOR, BUSHING; and BUSHING, ELECTRICAL CONDUCTOR. Excludes BUSHING, DRILL, JIG.
What is a Rod End Plain Bearing? 11 Items
A Rod End Plain Bearing (BEARING,PLAIN,ROD END) is a detachable assembly in or on which a journal, gudgeon, pivot, or the like moves. It is used to carry a load and to reduce sliding friction. It does not employ rolling elements. The outer member of the assembly is modified to provide a shank. The inner member may be either a plain spherical bearing or a sleeve bearing. Excludes BEARING, PLAIN, SPHERICAL and BEARING, PLAIN, SELF-ALIGNING.
What is a Thrust Washer Bearing? 18 Items
A Thrust Washer Bearing (BEARING,WASHER,THRUST) is an item of any peripheral shape usually having one flat or spherical surface and a centrally located hole. It is designed for applications involving moving (kinetic) loads. Except for items fabricated from bearing quality synthetic (plastic) or composed of multilayer material, one bearing surface must either have a specific surface finish designation of 32 microinch (0.8 micrometre) or less, arithmetical average (aa) (arithmetic mean deviation) or one of the following conditions: be lapped or ground; have visible or detectable means of lubrication; grooves, indentations; or self-lubrication. The thickness must not exceed 25 percent of the outside diameter of the shortest distance between peripheral flats (when thickness and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance). Excludes straight, tubular (without flange) items having a bearing surface(s) parallel to the axis of the bore only. See also WASHER, FLAT and SPACER, SLEEVE.
What is a Sleeve Bearing Half Set? 28 Items
A Sleeve Bearing Half Set (BEARING HALF SET,SLEEVE) is two or more identical or different sizes or types of BEARING HALF, SLEEVE packaged or grouped together for single issue as a unit, for replacement of worn and/or damaged bearings. See BEARING HALF, SLEEVE. Excludes BEARING SET, SLEEVE.
What is a Sleeve Bearing Half? 49 Items
A Sleeve Bearing Half (BEARING HALF,SLEEVE) is a half of a two-piece split type BEARING, SLEEVE.
What is a Linear-Rotary Motion Roller? 82 Items
A Linear-Rotary Motion Roller (ROLLER,LINEAR-ROTARY MOTION) is a cylindrical body having a centrally located hole to accommodate a pin or shaft for attachment to a push rod guide, yoke, rocker arm, turntable, or rail. The item provides a rolling contact with the face of a valve stem, or the lobes of a cam ring or camshaft on engines, fuel injection pumps, latches, turntables, parallel bearing surfaces requiring a roller support, and the like. Excludes BEARING, ROLLER, CYLINDRICAL; ROLLER, ELECTRICAL SWITCH; and friction bearings. See also CAM FOLLOWER, NEEDLE BEARING.
