Our e-learning platform offers valuable online tools, tutorials, and courses on a variety of topics – from basic bearing knowledge, to troubleshooting, to solutions for challenging environments.
The cage is responsible for keeping the rolling elements apart and guiding them. The materials used include steel, brass and plastic. Solid metal cages can be produced using machining techniques, while pressed cages are made from sheet metal. Similarly, plastic cages can be machined from solid plastic or injection moulded.
Nowadays, bearings are one of the most commonly used machine parts because their rolling motion make almost all movements easier and they help reduce friction.
Radial bearings and axial bearings Bearings can transmit loads in a radial direction or an axial direction (thrust) and in many cases there is a combination of both radial and axial loads to transmit.

Both designs are available as ball bearings or roller bearings. The choice of bearing design depends upon the application in question. Technical Insight - Choosing the Right Bearing and Arrangement
Rolling elements are either balls, rollers, cones, spheres or needles. They are usually made from a special high-purity, chrome alloy steel. Special materials such as ceramic and plastics are also used.
Special materials such as ceramic and plastics are also used. Although plastics cannot withstand extremely high temperatures, they are considerably lighter than steel. This makes them invaluable in sectors such as the automotive industry, where every gram matters. Technical Insight - Materials for Bearings
The inner and outer ring are usually made from a special high-purity, chrome alloy steel. This material has the necessary hardness and purity – both important factors for a high load rating and a long service life. Technical Insight - Bearing Life
The rolling elements roll on the specially formed raceways of the rings or discs and are kept apart and guided by the cage.
Rolling bearings and sleeve bearings In a sleeve or plain bearing, the axle and the bearing move in opposite directions on a sliding surface. By contrast, the two components of a rolling bearing that move towards one another – the inner and outer rings – are separated by rolling elements. This design generates significantly less friction than a sleeve bearing.
