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.
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.
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.
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.
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.
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.
Camshaft bearings are among the most underappreciated parts of an engine. Their purpose is to support the camshaft in the engine and allow for its rotation, preventing detrimental friction from causing serious damage to the heart of your aircraft. An engine features between one and seven bearings on each camshaft, this number varying depending on engine type. Generally speaking, there are three configurations of camshafts: overhead valve design, overhead camshaft with rocker arms, and overhead with direct camshaft operation. The configuration affects where the bearing is applied and the load it bears.
Gear bearings are, as their name implies, a combination of both gear and bearing functions in one component. Like gears, they feature teeth that intermesh with one another, and like bearings they do so to transfer radial and axial loads to bear weight and friction. Gear bearings improve drives in electrical, internal combustion, and turbine motors. The gear bearing design incorporates rifle-true anti-backlash, improved thrust bearing performance, and phase-tuning techniques for superior low-speed reduction. Because they combine both gear and bearing functions, gear bearings can reduce weight, number of parts, size and cost, and increase load capacity.
A needle roller bearing is a type of bearing that utilizes small cylindrical rollers that reduce the friction of a rotating surface. In comparison to ball bearings, needle roller bearings have a large surface area that is in contact with the functioning part. These are useful in manufacturing because of their ability to handle relatively high loads in a compact design. They are the smallest and lightest of the roller bearing family which gives them the advantage in limited space situations.

Today we have many new advancements in bearing parts that are helping to improve the performance and life of bearings.Sour gas compressor bearings, which use three advanced materials:Silicon nitride, which is used in rolling elements; stainless steel, for use in bearing rings; and PEEK (polyetheretherketone), a high temperature plastic that can be used to create bearing cages. The use of these three materials are prolonging the life of the bearings, lasting over 10 times longer than their predecessors.
In 1879, the first CVT (Continuously variable transmission) was introduced and allowed for a more flexible system than the traditional mechanical transmission. As this design began to spread, many manufacturers began to develop vehicles utilizing the CVTs. It started first in a car, then motorcycles, then tractors, and finally aircrafts. This year we are met once again with technological advances that allows us to further improve the CVT. NSK Ltd, a global manufacturer of bearings, introduced a high-reliability low-torque ball bearing in 2011 during the month of July.

A gyrocompass is a useful marine tool that is able to detect true north better than the conventional compass. The direction it points to is not affected by the Earth’s magnetic field or by the steel some ships are made of. In other words, the things that typically create inaccuracies in a compass, do not deflect a gyrocompass.
