Precision slewing ring bearings are a type of angular bearing that consists of two concentric rings with balls or rollers that enhance movement in load-bearing and power transmission applications. The two rings may be constructed with toothed gears to increase torque and can facilitate movement in any direction from the center of the bearing. They are ideal for use in low-speed, heavy load applications such as construction and excavation, or more intricate and precise such as medical tools and devices. Overall, there are many benefits to using precision slewing rings bearings.

Bearings are used extensively in the food and beverage industry as components in a variety of food processing and packaging machinery. Food-grade bearings must endure extreme conditions in many applications, so the life and performance of bearings used in these applications are influenced largely by the decisions of designers and engineers. Design considerations that may impact a bearing’s durability in food-grade applications include material, lubrication type, and shielding options. 

In the machine tool industry, spindles are a critical component used to shape materials through the use of high-speed rotation and pressure. As modern machinery advances, machining equipment is required to be faster, more precise, and more durable than ever before. Bearings are crucial parts that direct and enhance spindle movement. The use of high quality bearings, improves the efficiency and reliability of machine tool spindles, thereby increasing production and reducing wear and tear on machinery.

While metal bearings/bushings are common on the market today, there are certain applications that benefit from plastic bearings/bushings. These versatile components can take any number of forms and range considerably in style to work for the proper application.

Making beer is no small feat. It is both an art and a science that requires precise measurements
and the right equipment to create and re-create beers that consumers will love. What was once a
task reserved for giant alcoholic beverage manufacturers has become a labor of love for many
small brewers who created a craft beer movement across the country. Today's independent
brewers rely on a variety of other industries to get high-quality ingredients, machines, bottles, and more.

Oil seals, also known as grease or dirt seals, are an essential component of many machines and pieces of industrial equipment. An oil seal is designed to retain grease in a case or housing and close the gaps between stationary and moving components in pieces of machinery.

An example of this in the automotive industry is the seals within gear boots that enclose a car’s CV axles. Of course, there are many different applications across industries in which oil seals prevent the escape of vital lubricants and ensure the continued smooth operation of the machine in question.

Exposing a bearing to an electric current can cause electrical bearing damage. The damage manifests as pits and grooves on the bearings' surface create an uneven surface texture causing additional noise, vibration, and (eventually) complete failure. These outcomes can be costly, often leading to unnecessary downtime and expensive repairs or upgrades.

Although not all bearings are damaged by an electrical current and not all circuits cause bearing damage, there are two situations in which the problem typically occurs: when equipment is grounded incorrectly or when bearings are used in AC/DC motors with variable frequency drives (VFDs).

Motor shaft voltages have the potential to damage the components around them. If a shaft’s voltage exceeds the insulation capabilities of nearby cables or parts, it can cause both long-term and acute damage to motor bearings.

Some high voltages can even lead to arcing between the shaft and the bearing. When this occurs, the arcing rapidly elevates the temperature of the bearing. Metal can vaporize and become permanently damaged and pitted from this process. 

To perform at optimal levels, bearings require sufficient lubrication. When properly applied, lubricants can reduce friction, which reduces the amount of wear and tear experienced by the bearing part. Additionally, some types of lubricants can provide recirculation which serves as a cooling method, while other types can help to disperse heat buildup to improve system performance.

All of these characteristics help prevent damage to the bearing, as well as prolong its overall service life.
