Prior to the mid-20th century, most branches of the United States government had entirely independent cataloging systems that made procurement very inefficient and caused duplicated inventories. To create a unified supply chain, the Federal Catalog System was established so all federally-approved parts are labeled with standard identifiers, such as National Stock Numbers (NSNs) and National Item Identification Numbers (NIINs). While using these identifiers is mandatory across the U.S. government and NATO nations, their utility has prompted some private sector organizations to adopt them as well. If you are considering employing NSN and NIIN part classifications for your own procurement tasks, read on as we explore how they are set up and a few of the ways they can make your job easier. 

The effectiveness of global defense supply chains depends on the ability of buyers to accurately identify and source items across diverse organizations, systems, and international partners. To address these challenges, National Stock Number (NSN) data is widely used to support consistent item classification and identification across defense environments. To better understand such information, this blog will examine the structure of a National Stock Number and discuss the advantages that NSN information can offer buyers who need to source defense parts.

Aircraft procurement operations often require sourcing large volumes of parts to support a range of systems and maintenance needs. When those items are identified and cataloged with National Stock Numbers (NSNs), procurement data can often be structured more consistently, supporting clearer comparison and analysis across various environments. In this blog, we will examine where NSNs can offer analytical advantages over part numbers, discuss the types of insights they can reveal more efficiently, and review key challenges that can limit the effectiveness of analytics efforts.

Bearings are employed in countless areas of aircraft and spacecraft, supporting smooth movement for turbine shafts, landing gear, and more. Like any item intended for aerospace use, bearings are required to comply with multiple standards that address geometric tolerances, material quality, inspection methods, and supply chain traceability. In this blog, we will cover some of the most notable standards and certifications that aviation bearings are governed by to assure they perform as intended.

Relays are components in electrical systems that play a vital role in controlling the flow of electricity and protecting circuits. Among the diverse types available, power relays stand out due to their ability to handle higher currents and voltages, making them indispensable in a wide range of applications. Understanding power relays and their various uses can offer valuable insights into how electrical systems function, so read on as we provide a simplified overview.

When it comes to transporting goods efficiently and swiftly in various industries, conveyor systems play a pivotal role. Among the many conveyor systems available, rail conveyors have gained popularity for their reliability and versatility. In this comprehensive blog, we will delve into the world of rail conveyors, exploring what they are, how they work, their applications, and the role of electric motors in powering these systems.
