Needle roller bearings are a common form of bearing element, capable of supporting loads while facilitating motion and deterring friction that occurs between moving parts. As compared to other common forms of roller bearings, needle roller bearings are most notable for their cylindrical rollers that typically have a length four times the size of their diameter. With this general design, needle roller bearing components regularly support applications such as the functionality of rocker arm pivots, pumps, transmissions, compressors, drive shafts, and much more. In this blog, we will discuss the installation and inspection process of needle roller bearings, ensuring that you are able to best take advantage of such components for your operations and projects.

Motors devices that are essential to many various applications, capable of transforming one form of energy into mechanical energy that may be harnessed by connected components and systems. There are numerous forms of motors that one may take advantage of, the major difference between each being the type of energy that is transformed. One notable example is the hydraulic motor which utilizes hydraulic pressure to create torque and angular displacement, and it is regularly used as a form of linear actuator. In this blog, we will discuss the hydraulic motor in more detail, allowing you to be more familiar with its basic operations and the subtypes which are available.

Depending on whether your application requires the bonding of separate materials or to block the flow of gasses or liquids, it is crucial to use the proper adhesive or sealant. While adhesives bond two separate substrates together by chemically overcoming the forces of their separation, sealants block fluid flow through a surface, gap, or joint by filling in the space between the separate substrates. These two substances have many differences in their form and function which will be explored further in the following blog. 

When systems take advantage of pneumatic or hydraulic technology for basic operations, it is crucial that pressure levels are able to be monitored and tracked to ensure that pressures are within optimal ranges or levels. Pneumatic and hydraulic pressure technology can be found in anything from vehicle braking systems to hydraulic presses, and incorrect pressure levels can potentially raise the risk of flammability, leaks, accidents, and other such dangerous incidents. As such, pressure sensors are a common element that may either monitor or control pressure levels, and we will discuss them in brief detail so that you may understand them better.

Pneumatic actuators are a safe source of motion control that is powered by stored energy in the form of pressurized gas. These devices are essential components employed in various industries, especially for opening or closing valves. They are particularly valued because they do not require heat or electricity and therefore present a very useful option in areas where these can present a safety risk. For more information about what pneumatic actuators are and how they function, read on as we discuss the characteristics that make pneumatic actuators a vital component in so many operations.

Inductors are two-terminal components that are utilized for filtering, timing, and power electronics applications. They store energy in the form of magnetic fields while current is flowing. When an electromotive force is induced, inductors also have the ability to oppose a change in current. An inductor can also work like an open circuit for AC signals and as a short circuit for DC signals. It is important to note that the unit of inductance is Henry (H).

Using fuel control systems allows your engine to operate at a steady pace, with measured amounts of fuel entering the combustion chamber to maintain optimal fuel pressure levels. In certain engines, the fuel is measured in multiple cylinders prior to being injected into the engine. Today, engines are often equipped with multiple cylinders that function independently; however, earlier electronic fuel injection (EFJ) systems functioned differently. This blog will explore how former models of EFJ systems transformed into the individual cylinder fuel control systems we see today in order for you to better understand the way fuel is measured and regulated in many modern engines.

A varistor is a passive, two-terminal semiconductor device used for eliminating the voltage spikes in AC voltage. It protects electrical and electronic devices from overvoltage transients via voltage clapping. Varistors can automatically change their resistance value with the change in voltage across them.

According to some engineers, lubricants are simple byproducts of the former Industrial Age. The lubrication of machine bearings is a long-standing practice that has seen various advancements over time such as the tweaking of chemicals, leading to modern day solutions that are commonly used to minimize friction. Still, the introduction of oil-based lubricants in the late nineteenth century accelerated today's modern lubrication methods.

Digital isolators are used in a variety of applications to isolate digital signals by use of CMOS and similar components. Used in high-speed multichannel circuits, serial interfaces, and logic analyzer applications, digital isolators play an essential role in signal transduction. In this blog, we will discuss the basics of digital isolators while describing their importance in high-caliber circuitry.
