Limit switches are electromechanical devices that detect when an object moves further than its predetermined limit, quickly interfering to prevent it from causing unwanted damage. Most often, they are used alongside industrial machinery as a way to keep individual moving parts working at their best. As a form of proximity sensor, they follow a set of principles which are designed to observe once an object has passed a defined limit to its movement. However, unlike similar sensor devices, limit switches detect movement by making physical contact with the target object. This simple mechanical design offers certain advantages as well as a few major limitations. While there are a plethora of variations, this article will focus on limit switch designs that are used in the control and actuation of industrial valves.

Bearings are crucial devices in industrial machinery that facilitate the smooth transition of movement between components. They come in many forms, but one of the most durable of the many types is the tapered roller bearing. As a result of their cone-like shape, these bearings are able to support large loads in multiple directions, lending great versatility to many industrial applications. Therefore, they have found use in many heavy-duty operations where bearings are often subject to large loads of varying directions. To find a roller bearing type which can best suit your operational needs, we invite you to read on ahead.

Before the introduction of the Airbus A320 family of planes, all aircraft had a central yoke in their cockpits. The original yoke was a two-handed tool which pilots could use to manually control the aircraft’s functions. Then in 1985, Airbus designed the first commercial airliner with a side stick in place of the central yoke. Up until that point, fighter jets were the only ones using side stick navigation. Now, nearly all modern Airbus aircraft use side sticks, while Boeing has committed to keeping the central yoke. After this, if you are curious what is the difference between these configurations, simply read on as we discuss the ways in which they vary.
