Washers are machine components that find use in countless assemblies. Typically used in conjunction with a screw fastener such as a bolt and nut, washers  keep such components from loosening. More than that, they distribute the load from the nut or bolt head over a larger surface area, reducing wear over time.

Rollers are widely used components that facilitate movement to various machine parts as well as provide support and transportation to materials moving through the machine. Rollers can be utilized for a variety of different functions, and as such, they come in many different types in order to suit many industrial applications. In this blog, we will give a brief overview of the most common types so you may get familiar with such components and know what kind of roller you need for your operations. We will begin by outlining the different materials they are available in. Rollers are typically made of either urethane/rubber, metallic, or resin.

Bearings are a common component for numerous types of machinery, regularly implemented within assemblies for the means of minimizing the amount of friction generated between two moving surfaces. There are many types of bearings that one may use for friction reduction, and each may provide its own unique abilities to benefit certain applications. Jewel bearings in particular are a form of plain bearing that features a hard gem for their design. Due to their construction and design, such aviation bearing types are well suited for surviving some of the most extreme environments, all while remaining accurate and reliable. In this blog, we will provide a brief overview of the jewel bearing, allowing you to better understand their functionality, advantages, and common uses. 

Bearings and bushings are used in a multitude of applications from complex aerospace machinery to simple clocks. They are a small component, yet there are many different variations because each one supports different loads and performance. So, what exactly are they?
