Federal Supply Classes (FSCs) are essential for streamlining the procurement and management of a vast range of items, especially for the benefit of buyers and purchasing managers operating within industrial sectors. This is because FSCs offer a simplified means to locate and purchase items based on their general application and features. In this blog, we will introduce readers to FSC 3130, a popular class which serves to organize mounted bearings that find use across industries.
Mounted bearings are self-contained bearing units that include a housing and a bearing, generally being designed to provide ease of installation, whether it is bolted to a structure or secured by other means. Mounted bearings differ from standard bearings in the fact that they are already integrated into a housing, simplifying maintenance and use.
Mounted bearings find use in a wide range of industrial settings, with notable applications including conveyor systems, power transmission equipment, agricultural machinery, and many other types of machinery. Their versatility also makes them indispensable to numerous other industries, where they are featured within assemblies ranging from simple furniture and consumer products to advanced machinery and vehicles.
Pillow block units are one of the most commonly used types of mounted bearing, specifically being designed to support assemblies that exhibit moderate to heavy loads. Like other options, they offer the advantage of being easy to install and maintain for reliable service.
Cartridge units are compact mounted bearings that are popularly used in tight spaces, where they are able to take on light to moderate loads. A notable example of this is within packaging machinery.
Takeup units allow for the adjustment of shaft tension to be carried out, being essential for maintaining proper tension for conveyor systems and other applications featuring belts and chains.
Hanger box units are designed to be suspended from a support structure, benefiting overhead conveyor systems and other applications where a shaft needs to be secured from above.
Flat box units are designed to be mounted on a flat surface, their compact design and simplified installation benefiting space-limited applications.
Step box units are similar to flat box units, though they differ in the fact that they have a stepped design. This allows for a greater load capacity to be achieved, making such units popular for heavy-duty applications.
Several types of mounted bearings exist, each with its own set of characteristics and applications. The most common examples include ball bearings, roller bearings, and sleeve bearings, which we will briefly cover below.
Ball bearings are relatively quiet during operation and can reduce friction for many applications, making them useful for assemblies that involve light to moderate loads. For example, such hardware is common in electric motors and other high-speed equipment.
Roller bearings are used for heavy-duty applications like construction equipment and heavy machinery, a result of their ability to handle higher loads when compared to ball bearings.
Sleeve bearings are a simplistic and cost-effective option for fans and other light-duty equipment, capable of handling lighter loads with ease.
