What is a Sleeve Bushing?

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.

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 - Singapore (SG)

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.
