Despite being an essential component of an aircraft, engine mounts are frequently underappreciated and underrated. While overlooked, engine mounts are actually a sophisticated part of achieving proper aircraft operation. That being said, we will provide a brief overview of why these seemingly fragile mechanical components are important.

Across a variety of industry verticals, one will typically find jaw couplings being used for power transmission in large, industrial machines. That being said, they often find homes in smaller, standard power transmission applications, and they offer the unique advantage of not requiring lubrication for mitigating movement. Made up of three components, two jaws and an elastomeric spider, jaw couplings operate in a single plane between two hubs to transmit power from a driving hub to a driven hub. For your better knowledge, this blog will take a closer look at jaw couplings, how they are used, and the advantages of different designs.

A micrometer is an instrument used for making very fine measurements of dimensions such as length and diameter. Micrometers typically consist of a C-shaped frame with a moveable jaw that is operated by an integral screw. Metric micrometers in particular, generally measure in 0.01mm increments and imperial versions in 0.001 inches. Due to their size and design, micrometers can provide much more accurate measurements than other devices, such as dial or vernier calipers but this is highly dependent on the user’s care.

Used in a diverse range of environments from workbenches in garages to landing gear on aircraft, caster wheels are versatile rolling devices that may be used to effectively support a load. Typically, casters contain a single wheel that is housed within a frame and are often used on the bottom of furniture and heavy machinery to allow them to roll smoothly across the floor. This allows for heavier objects to be moved with ease when they are too heavy to lift, or could otherwise cause undue strain on the person carrying them. They may be made of metal, plastic, wood, or other materials for varying capability and resistance to environmental factors. With an array of uses, there are many different types of caster wheels available, the most common of which are described below.

Plate Casters: As the most common type, plate casters are characterized by their flat, square-shaped mounting surface. Often, they will have four holes, one on each corner of the mounting device, that are used to secure the plate caster to an object. To install, bolts or screws can be used for a permanent hold. Aside from providing easy installation, the square shape of these casters has excellent weight distribution so they are often preferred for larger loads.

When you are in need of impedance matching and step or step down operations in audio applications, audio transformers are needed. Essentially, an audio transformer transmits and modifies input electromagnetic signals into output signals through inductive coupling. To better understand how audio transformers work and why they are important, this blog will provide a brief overview of these electromagnetic devices.

Lockbolts, as their name suggests, are bolts that lock in place when installed, preventing loosening over time, even under extreme stress and vibration. They find use in a wide range of applications where rivets or conventional bolts are often utilized as lockbolts display increased strength when compared to other options. To better understand lockbolts, this blog will outline their uses, types, and unique features.

There are many circumstances in a circuit or other electronic device where signals must be sent between physically isolated circuits. Although there are several solutions that may accomplish this, semiconductor technology has proven to be optimal for its size and operational lifespan. One such technology that has found use in high-speed multichannel circuits, serial interfaces, and logic analyzers, is the optocoupler. As more industries continue to adopt optocouplers, it is critical to understand the basics of their design and operating principles. In this blog, we will discuss everything you need to know about optocouplers, highlighting their importance in high-performance circuitry.

In order for pressure gauges to continuously provide accurate readouts, they must be regularly calibrated using the correct technique. Although calibrating these precision gauges takes time and involves thorough attention, it is entirely necessary to avoid costly errors. Whether you are an expert in this field or have never worked with pressure gauges before, it is beneficial to review the essential details associated with the calibration process. In this blog, we will discuss everything you need to know when it comes to pressure gauge calibration.

When it comes to aviation safety, every event, from taxiing to parking the aircraft, should be treated with an equal amount of respect and attention to detail. While most consider the flight to be over as the plane approaches the apron, mistakes involving the parking brake may result in significant damage and expenses. Although the majority of aircraft use chocks placed by ground crew members to park the vessel in the correct place, there are several circumstances where the tarmac is off-limits for personnel. Additional cases where parking brakes are employed to maintain aircraft position include deicing, ramp holds, and emergency stops. In this blog, we will detail the design and function of the parking brake in order to give you a better understanding of this often unappreciated component.

When a pilot is operating an aircraft, there are various flight conditions that they must keep an eye on for safety and efficiency. One of the most important values to know during flight is one's altitude, that of which is the distance of the aircraft in relation to the ground below it. There are various ways in which altitude may be measured, one common way being the use of an aviation radio altimeter, or aircraft radar altimeter. With a radio altimeter, the distance between the aircraft and the terrain below can be determined with ease, allowing a pilot to conduct a safer landing in low-visibility conditions. In this blog, we will discuss the functionality of a radio altimeter and its design, allowing you to better understand how such devices are used.
