NATO Supply Class 2530 is a classification within NATO Supply Group 25, which is dedicated to Vehicular Equipment Components. Specifically, Class 2530 focuses on Vehicular Brake, Steering, Axle, Wheel, and Track Components.
This class includes various components that are essential for the proper functioning of a vehicle's braking, steering, axle, wheel, and track systems. Some examples of items that fall under this class include brake drums, brake shoes, brake pads, brake calipers, steering gears, steering columns, axles, wheels, and track components.
These components play a crucial role in ensuring the safety, stability, and maneuverability of vehicles. They are designed to withstand the demanding conditions and requirements of military vehicles, which often operate in challenging terrains and environments.
NATO Supply Class 2530 is important for military logistics and procurement purposes, as it helps in standardizing the classification and identification of these specific components. This classification system facilitates efficient inventory management, supply chain operations, and maintenance activities for military vehicles.
When procuring or maintaining military vehicles, it is essential to refer to NATO Supply Class 2530 to ensure the correct identification and sourcing of the necessary brake, steering, axle, wheel, and track components.
Includes Turrent Brakes; Clutch Brakes, Tank Turret.
Note-The term "vehicular" as delimited for group 25, is applicable to those vehicles and tractors included in groups 23 and 24, construction vehicles included in group 38, and warehouse trucks, tractors, and trailers included in group 39. It does not apply to railway vehicles (group 22), aircraft (group 15), or watercraft (group 19). An item of supply which is a "vehicular" component, within the scope delimited above, is classified in this group regardless of whether it has additional applications on vehicles outside the delimitations for this group.
