The Common Applications of Unmounted, Antifriction Bearings

For professionals working with systems that rely on smooth, efficient motion, understanding FSC 3110 and the parts within it is essential. This classification encompasses unmounted, antifriction bearings, including individual components like balls, rollers, and races, which are critical for minimizing friction in rotating and reciprocating mechanisms. In this blog, we will explore the purpose of FSC 3110 and the specialized bearing components it categorizes, highlighting their role in diverse applications.

The Importance of Federal Supply Classes

Federal Supply Classes (FSCs) serve as a standardized system used by the U.S. government to categorize and manage the vast array of items it procures and maintains across multiple sectors. By organizing components into specific classifications, FSCs ensure consistency in identification, tracking, and distribution, regardless of the specific application. Furthermore, this system enhances supply chain efficiency, allowing for the rapid sourcing of critical parts and improving inventory management.

Why is FSC 3110 Needed?

FSC 3110 is defined as “Bearings, Antifriction, Unmounted,” featuring bearings specifically designed with balls or rollers that minimize friction in mechanical systems. The term "unmounted" refers to bearings supplied as individual items rather than being full assemblies in a housing or complete unit, which extends to including components like balls, rollers, and races separately. This unassembled format offers greater flexibility, allowing engineers and maintenance teams to select, replace, or customize components as needed to integrate with specific machinery.

Unmounted bearings are classified separately from other bearing FSCs because they provide enhanced customization options. This distinction is particularly valuable in industries with precise and demanding load, speed, and space requirements. By maintaining a dedicated classification for unmounted, antifriction bearings, FSC 3110 ensures that professionals can efficiently source tailored configurations for their systems.

Notable Industry Applications of FSC 3110 Bearings

As a result of the flexibility they offer in designing and maintaining systems, the bearings that fall under FSC 3110 serve a wide range of industries, including:

Aerospace: Bearings are essential in aircraft landing gear, flight control systems, and jet engines, where they must enable smooth movement in the face of extreme temperatures, high speeds, and significant mechanical stress.
Automotive: Cylindrical rollers and thrust bearings can be found in transmissions, wheel assemblies, and steering systems, providing the durability and load-bearing capacity needed for seamless operation and long-term performance.
Industrial Manufacturing: Continuous-use systems like pumps, motors, and conveyors all benefit from bearings to minimize friction, reduce wear, and maintain efficiency.

Examples of Parts within FSC 3110

FSC 3110 includes various individual bearing components that work together to minimize friction and support smooth movement, as well as finished assemblies. Some of the most notable examples include:

Bearing Balls: Precision-engineered, round rolling elements used in ball bearings to provide efficient load distribution.
Cylindrical Rollers: These elements are wider and provide higher load-carrying capacity than standard bearing balls, which makes them ideal for heavy-duty applications.
Tapered Rollers: These rollers are designed with one side bigger than the other, enabling them to handle both radial and axial loads in high-performance applications.
Needle Rollers: Long, thin rollers that fit into compact spaces while supporting high radial loads.
Bearing Races: The inner and outer rings that guide the rollers or balls, crucial for a fully-assembled bearing.
Complete Assemblies: Pre-assembled for immediate use, these assemblies come in diverse types to accommodate varying loads. For instance, ball bearings are fitting for most standard applications, thrust bearings manage loads in systems where force is applied along the axis of rotation, and roller bearings are designed for high-load applications.
