What Is an Axial Load Bearing?

In general, bearings are placed in a variety of mechanisms to guide rotating, oscillating, or linear motion with little to no friction, all while maintaining proper spatial alignment while supporting applied loads. As imposed forces can vary between setups, either imposing radial loads that are perpendicular to a rotating shaft, axial loads that act along the centerline, or a combination of both, no single bearing design will be able to accommodate them all. With this in mind, we will explore more about axial load bearings in this blog, including which types may be best for particular situations and some of the installations you can find them in.

What Constitutes an Axial Load Bearing?

Simply put, axial load bearings are designed to absorb force along the direction of a shaft when installed, preventing forward or backward sliding movement under pressure. While axial load bearings vary in form to perform different tasks, their most crucial design is the internal direction in whi......Read more >>

What Are Ball Bearings? Types, Applications, and How They Work

Many forms of industrial machinery and aerospace systems are often alike in the common use of rotating or moving elements for functionality, where continuous, low-friction rotation is absolutely necessary to avoid premature component failure. When such issues are a concern, the first choice of many engineers or designers will be ball bearings. Generally speaking, these components are recognized for their ability to reduce rotational friction by replacing sliding contact with rolling contact, directly extending the service lives of the shafts and housings they support. Because different bearing designs will handle load and speed very uniquely from one another, ensuring that ball bearings are the right option for your own needs requires a basic understanding of their functionalities, uses, and variations.

What Are Ball Bearings?

In its most simplistic form, a ball bearing is a mechanical hardware component that uses spherical rolling elements to keep two moving surfaces separated......Read more >>

How to Decode and Look Up National Stock Numbers (NSN)

While it is common for government and defense procurement endeavors to begin with buyers only having simple information like product descriptions or manufacturer part numbers in need, such data does not always prove sufficient for ensuring a timely and accurate search. This is because of the fact that there is no standardization for such information, where two completely different items from separate manufacturers could possibly share the same part number. Among other concerns surrounding less concrete forms of search data, buyers often turn to National Stock Numbers (NSNs), which are standardized, 13-digit identifiers that are assigned to items of supply to provide a universal reference for management and trade. For buyers looking to conduct an NSN part number lookup for items of need, understanding the basics of the system and how to identify the NSN of any product is a must. This is what we will seek to discuss in this blog, so be sure to read on to learn more about NSN interpretati......Read more >>

Finding the Right CAGE Code Made Simple

Government and defense organizations across the globe often take advantage of standardized identifiers and widely recognized forms of listing data to distinguish between the organizations associated with diverse parts or contracts, with the Commercial and Government Entity (CAGE) Code being particularly notable for its ability to offer a consistent reference for a specific entity at a particular location. In the United States, CAGE Codes are strictly administered by the Defense Logistics Agency (DLA) to entities that are approved for engaging in government contracts and supply management, making the identifier a common tool for procurement activities. However, the challenge for buyers is often determining which particular code corresponds to the entity or facility shown in a given requirement, where purchasing decisions must be made carefully to avoid any issues for compliance.

What Are Flanged Bearings? Benefits, Types, and Industrial Applications

Maintaining operational continuity in aerospace and heavy industrial sectors commonly demands close attention to mechanical wear and system stability, especially when it comes to any equipment that involves moving elements. This is because a single rotating assembly failure can easily halt production lines or compromise safety-sensitive flight linkages, among other issues. For this reason and others, it is necessary that procurement and maintenance teams leverage suitable hardware that can withstand heavy radial and axial loads without losing alignment over time.

In many high-vibration environments, standard bearings can be prone to shifting out of place, leading to problems like accelerated friction, premature wear, and potential system failure. Flanged bearings are a more specialized variation that addresses such concerns by providing a permanent structural stop, making them a useful solution for prospective buyers. For sourcing teams who are seeking to make more informed purchas......Read more >>

Understanding FSC Codes for Government Parts

In government procurement, knowing what a part is called or how it is organized within manufacturer-specific databases does not always tell buyers where it belongs within a much larger supply catalog, nor does it offer a standardized means for carrying out searches when fulfillment is necessary. This is especially relevant in government supply systems, where catalogs and purchasing lists can contain a plethora of individual item records to cover everything from aircraft components and electrical hardware to tools and other support equipment. To bring more order to the process of managing and browsing extensive supply options, the Federal Supply Classification (FSC) system was created to classify various items together by shared features, functionalities, uses, etc. Understanding how these codes are structured and how they relate to identifiers like National Stock Numbers (NSNs) can make large government supply catalogs easier to navigate, so be sure to read on as we offer a helpful gui......Read more >>
