The aircraft engine is paramount for standard flight operations, allowing for fuel-and-air mixtures to be combusted for the means of generating the necessary propulsion for lift. While in flight, engines and other aircraft apparatuses are constantly exposed to various stressors and elements, thus warranting the need for robust assemblies that can guard sensitive components. The nacelle of an aircraft is the housing that serves to protect the engine from such elements while increasing aerodynamics. Alongside guarding the engine, they also house instruments, fuel tanks , weaponry, and other equipment. In this blog, we will discuss the design and components of the nacelle, allowing you to better understand their use and importance.

Bolts are indispensable components found in machines that we encounter daily. In fact, bolts are one of the most common and diverse fasteners on the market. Bolts come in a variety of shapes and sizes which will determine their application. In this blog, we will discuss how a bolt works, what the different types are, and the difference between a bolt and a screw.

O-rings and gaskets are two common hardware components that are regularly compared to one another, both often being used to produce a seal between two or more mating components. O-rings and gaskets are found in countless assemblies ranging from plumbing assemblies to advanced machinery, serving to prevent leaking for the benefit of assemblies. Despite their shared role, both components do have their own unique designs and features that set them apart.

Bearings are common elements of moving assemblies, serving to bear loads and reduce friction between contacting surfaces in motion. Thrust bearings in particular are a more specialized type, capable of taking on the axial loads of rotating devices. Such bearings can come in a number of forms to cater towards different applications and requirements, and common types include rolling element thrust bearings and fluid-film thrust bearings. In this blog, we will discuss the main thrust bearing types that are available on the market to help you find exactly what is needed for your operations.

Bearings are common elements found in applications ranging from clocks to industrial machinery, implemented within assemblies to reduce friction between moving surfaces and to smooth rotational motion. While bearings serve to prevent the quick breakdown of various assemblies, they themselves can also face wear and tear over time. In order to maintain the service life and reliability of bearings, one must conduct regular maintenance and proper handling procedures.

Fasteners are extremely common elements for aircraft construction, often accounting for half of the total parts of many popular airline models. As fasteners are components tasked with joining parts together to form assemblies, they can come in a plethora of types to accommodate diverse needs and materials. While common fasteners such as rivets, bolts, screws, and nuts are well discussed in the aviation sector, some may be unfamiliar with the more specialized types that serve important roles for aircraft construction. In this blog, we will provide a brief overview of some of the special types of aircraft fasteners that are commonly used, allowing you to understand their applications and importance.

Machine pins, also known as pin fasteners, fastening pins, or simply pins, are a type of specialty fasteners used to align and join two components together. Pins are available in semi-permanent and quick-release models. Semi-permanent pins may require additional pressure or tools for installation and removal, while quick release pins will typically feature a spring-loaded mechanism which locks them into place to allow for easy installation and removal. Additionally, pins come in a broad range of sizes and materials with different designs to suit a wide array of applications.

Pillow block bearings are a type of housed bearing unit used with a machined mounting surface and found in mechanical power transmission systems where they support shafts and couplings. The shaft is perpendicular to the mounting screws and parallel to the mounting surface. Pillow block bearings can come in many types, such as ball bearing, cylindrical bearing, tapered roller bearing, or synthetic bushing. In this blog, we will discuss the basics of pillow block bearings.

A flanged ball bearing is a type of ball bearing specially engineered to provide a precise mounting. This is done through the axial location of the bearing’s shaft ends, which stabilizes the bearing’s positioning to maximize the load support. When using a ball bearing with a shaft axis that is perpendicular to the mount, flanged bearings facility either rotary or linear movement. There are many types of bearing flanges, each with differing designs and cages tailored to their specific ball bearings to maximize their loading and speed capabilities while enabling the two devices to function harmoniously. Flange bearings are screwed in relation to the shaft axis, meaning flanged roller bearings consist of an insert attached to a relatively flat housing structure.

A bearing is a mechanical component that may be implemented within an assembly to facilitate rotating motion and mitigate the forces of friction. As components that are tasked with the transferring of axial and radial loads to supporting structures, bearings must exhibit high amounts of precision and durability while ensuring noise and vibration do not become an issue. With the various common types of bearing components available on the market, automobiles, aircraft, construction equipment, and other vehicles and devices can all benefit from load bearing and friction reduction. In this blog, we will discuss some of the more common bearing types, allowing you to find which is best for your given application.

Electricity is an energy source that we now rely on for a grand number of applications, ranging from the powering of computers to lighting fixtures that illuminate spaces. As electricity can be derived from a variety of sources such as batteries and power grids, specific components are needed to transmit electricity correctly to accommodate a specific application. Known as power connectors, such components can come in a variety of forms to carry and transport voltage.

A bearing is a mechanical device used to prevent direct metal to metal contact between two elements in relative motion. This prevents friction and heat generation and ultimately slows the natural process of wear and tear. Furthermore, because bearings replace sliding motion with low friction rolling, energy consumption is also reduced. In addition to this, bearings also serve the purpose of transmitting loads from the rotating element to the housing. This load can be radial, axial, or a combination of both. Though a wide range of bearing types exist, they are generally separated into one or two major types: ball bearings and roller bearings. This blog will discuss both of these bearing types and their unique characteristics.

Despite aircraft being built from the highest quality materials, those materials would be rendered obsolete if they were not properly affixed to one another. This is where fasteners come in. Though they are small, seemingly insignificant parts, fasteners are the most critical part of an aircraft. Without them, aircraft could not be assembled, let alone withstand the extreme conditions they are subjected to during flight. In fact, in an entire aircraft, roughly half of all parts are fasteners.

Bolts, nails, and screws are all examples of fasteners. A lesser-known, but just as important fastener, is the rivet. A rivet is a permanent mechanical fastener used to join two plates together. Because rivets are permanent (meaning they cannot be removed) their joints are incredibly strong and similar to those of adhesive or welded joints. It is a cylindrical piece of steel usually made from low carbon, but can also be made from aluminum, monel (a type of nickel alloy), or copper, depending on the application’s weight and corrosion-resistance requirements.

A bearing is a machine element that controls relative motion and reduces friction between moving parts. The majority of bearings facilitate a desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the forces applied to the parts. One type of bearing, sealed ball bearings, differ greatly from open or shielded ball bearings. The main difference is that they cannot be re-lubricated once lubricant has broken out or begun to leak. Despite this feature often leading to a shorter lifespan when compared to properly maintained open or shielded bearings, sealed bearings have several benefits over other types of ball bearings. The three chief benefits of sealed ball bearings are that they require no maintenance, are not susceptible to contaminants, and cannot be over-lubricated.

D-subminiature connectors, sometimes called DB connectors or D-subs, are a versatile type of electrical connector. They derive their name from the unique D-shaped shield which protects all sides of the connector from both mechanical and electromagnetic interference. Additionally, the shields’ asymmetric shape ensures that it only attaches to its corresponding connector in the correct orientation. Within the D-sub, there are two or more parallel rows of pins (in the plug) or jacks (in the socket) aligned to match the equivalent contacts in the other half of the connector. The pins or jacks usually feature a gold tip surrounded by a layer of insulation made from a variety of materials such as glass or PBT, a plastic used for insulation.

Bearings are machine elements, implemented within an assembly to limit motion to a specific movement and to mitigate friction between moving components. When equipment and systems rotate while under operation, radial and axial loads are produced which may begin to cause damage if left unchecked. To prevent inevitable failure of the assembly, bearing surfaces are provided by bearings to compensate for the friction. Antifriction bearings, also known as rolling bearings, are components that carry an assembly load on rolling elements placed between races.

When you’re giving someone directions, odds are you’re doing so in relation to a separate location both you and the other person know. For instance, you might say something like “Go to the coffee shop on 5th Street and turn left.” This is because having an accepted position or reference point is extremely helpful in providing clear directions. This same concept is applied to astronomy, surveying, navigation, or any other related action.

Cams are a small component that many might not be aware of, but they may be found in dishwashers, automobiles, sprinklers, and many other applications and serve important functions. In general, their purpose is to transform rotary motion into linear motion, and there are many types that may be implemented. Despite their capabilities, cams themselves would be fairly useless if not for cam follower bearings.

DIN connectors are a type of electrical connector that feature various designs, standards, and capabilities to serve different applications. Electrical connectors are components that conjoin contacts, establishing an electrical circuit for a system and providing for applications that are power, data, and audiovisual related. DIN connectors were introduced in the early 1970’s by Deutsches Institut für Normung (DIN), a German national standards organization, and have greatly expanded since. In this article, we will discuss the various types of DIN connectors available, their methods of mounting, and the applications that they serve across various industries.
