Roller chains, also known as bush rollers, offer a simple and efficient solution for transmitting power as well as coupling a motor to its load. They are used in many types of common machines, from the more domestic such as cars, motorcycles and bicycles, to large industrial and agricultural applications such as printing presses and conveyers. ..

A coupling is a mechanical device that is used to connect two rotating shafts together, allowing them to transmit power. Elastomeric couplings, which fall under the category of flexible (non-metallic) couplings, are designed to not only transmit torque, but to accommodate for varying degrees of misalignment (up to 3 degrees) between the shafts as well. ..

Rod end bearings are mechanical joints that, while common and widely used, are essential in nearly all mechanical devices that require mechanical controls. Also known as heim joints (after their North American patent) or rose joints (after their British patent), rod end bearings are typically found in steering links, control rods, and tie rods – basically where any precision articulating joint is required or where a clevis end cannot be used. ..

Needle roller bearings are the smallest and lightest of the roller bearing family, which includes tapered, cylindrical and spherical roller bearings. In recent years, needle roller bearings have become the popular choice for design engineers and are being recognised for their technical advantages within specific applications. Their small, long and thin cylindrical rollers have a high length-to-diameter ratio, like a needle – hence their name. ..

Research into the manufacture and production of ball bearings has proved that only one percent should fail to reach their full-service life expectancy. That’s a very small percentage, which also proves that if your ball bearings fail, there must be a very good reason. Determining the reason for ball bearing failure can prevent future failures and provide essential information for proper planning and maintenance. ..

Bearings, specifically rolling element bearings, are found in nearly everything that has moving and spinning parts, from motors and gearboxes to conveyor systems and industrial machinery. While it’s easy to understand why these components are so common in so many industries, what you may not realise is that each device can be quite different from the other, depending on the specific application for which it has been designed. ..

We’ve covered how to know when your wheel bearings need replacing and how important it is to be aware of the signs of possible bearing failure. If you’re in a situation where your bearings need replacing and you plan on replacing them yourself, it's vital that you have the right tools for the job, as well as replacement parts from a trusted supplier. ..

Insert bearings are simply standard radial bearings that have been adapted to fit into a housing, which is why they are often referred to as adapted radial bearings. While they are commonly sold with a housing, they can also be purchased without one. Along with wide inner ring bearings, insert bearings are used in many different industries, from agriculture and food processing, to printing. ..

Flange bearings, also known as flange mounted bearings or flange units, are used to mount ball bearings to a perpendicular surface. The term ‘flange’ refers to a projecting flat rim, collar, or rib on an object, serving for strengthening or attachment or for maintaining position on a rail. ..

It’s not actually common for crankshaft thrust bearings to fail but when they do, the result can be catastrophic for the engine. Aside from the significant costs for repair, a thrust bearing failure can pose a serious safety threat to operators in the general area. So, what is the purpose of a crankshaft thrust bearing and why do they sometimes fail? Here we answer your questions and advise on how to prevent an engine disaster. ..
