Which rolling bearing is the right one for your purpose in terms of design and individual concept depends on various factors. The forces acting and the type of load are important influences.
Is it an axial force that acts or are radial forces generated? Does a high or rather low speed occur in the area of application?
The load rating is another decisive factor in avoiding unnecessary damage to your machines or systems and ensuring a long service life. Environmental influences such as temperature or the proportion of dirt particles in the air are also important. How much can the component weigh and what installation space is available?
Depending on the application, the housing and all other components of the rolling bearing can be made from different materials.
There are various types of shaft seals for the shaft, which seal the component against the environment. This prevents contamination of the housing. A distinction is made between axial and radial shaft seals. They keep the shaft tight in the long term to ensure a particularly long service life.
As a ball bearing manufacturer, we advise you on the ideal materials that match the properties for your area of application and are cost-effective. In this way, FUD ensures that in the end the price is right and you receive the best possible quality. It can be a good solution to manufacture parts of the component, such as the cage or housing, from plastic. This is lighter than metal.
Work with the experts from FUD to find the right design based on the factors influencing your requirements.
In addition to trading in rolling bearings from well-known manufacturers, FUD offers you even the most unusual individual solutions based on your drawing in cooperation with an engineering office.
This approach not only saves you time thanks to FUD's experience in finding solutions, you also avoid problems and unexpected failures in the test or later use phase of your machines or components.
In addition, FUD carries out tests to check the expected characteristics of the design so that you can be sure that your expectations are fully met.
Rolling bearings are among the most frequently used machine elements in which two fixed components are to be connected to each other in a movable manner. An example that is certainly familiar to everyone is a shaft that transmits force via a rotary movement and thus enables this movement with a form of rolling bearing. In the case of a roller skate or inline skate, the theoretical principle is the same as in the construction of systems.
A distinction is made between three types of rolling bearings
Axial bearing: only absorbs forces that act parallel to the axis of rotation and cannot build up a counterforce to radially acting forces.
Radial bearing: only absorbs forces acting vertically and cannot build up a counterforce to axial forces.
Combined radial-axial bearing: can build up a counterforce to both radial and axial forces. It supports forces in both directions of action.

A rolling bearing transmits movement, i.e. it brings together components that move against each other. The built-in inner and outer ring with movable balls or rollers reduces frictional resistance and leads to a more durable design of the component by reducing friction. Balls or rollers are used depending on the direction and load of the forces that occur.
Rolling bearings consist of an outer ring, an inner ring, a cage and rolling elements.
Mounting deep groove ball bearings: The balls are inserted into the outer ring in contact with each other. The inner ring is inserted eccentrically and pressed downwards so that it is concentric. The balls are now distributed at constant intervals. Finally, the cage is inserted to prevent the balls from rubbing against each other. If the rolling elements used are rollers, the principle works in the same way. Depending on which direction and load the occurring forces exert, balls or rollers are used.
In addition to the design of the rolling bearing, the lubricant used and the quality of the steel of the individual components are also important.
Rolling bearings have the advantage of low friction, which means that the heat generated and mechanical wear are low. The lubricant requirement is low, making them easy to care for and maintain. They can transmit higher speeds than plain bearings and can conduct three-dimensional forces, unlike linear technology components that only allow movement in opposite directions.
For example, if you have a high load in a small installation space and low speed at the same time, a plain bearing would be a better choice.
Our customer was using plain bearings that generated too much friction. The system's electric motors were loaded to such an extent that motor damage was increasingly occurring. FUD recommended a rolling bearing to the customer that reduced the rotational resistance of the motor. This significantly reduced energy consumption and increased the service life of the electric motors by 30%.
Rolling bearings and their balls or rollers are selected depending on the area of application, requirements and environmental influences. In addition to balls and rollers, barrels, needles, cylindrical or tapered rollers can also be used.
This in turn leads to a particularly long service life for the components and therefore the entire machine, as well as significant energy savings. Seals are used to keep lubricants inside the housing body and dirt particles outside.
The rolling elements all have the task of generating rolling friction and thus preventing the sliding friction that leads to wear, so that as little energy as possible is lost during the conversion and guidance of forces through the component, which reduces temperatures and minimizes mechanical wear.
There are the following types of bearing according to the direction of load
Axial bearings have the task of withstanding forces in the direction of the shaft. They are ideal for low speeds. A distinction is made between single-acting and double-acting thrust bearings.
Radial bearings are used when radial forces are transmitted. In many cases, a radial bearing has the property of transmitting axial forces slightly. Radial bearings include deep groove ball bearings, cylindrical roller bearings, needle roller bearings and barrel bearings.
There are six different basic types of rolling bearings
Ball bearings are the most commonly used form of rolling bearing, as they offer the widest range of different dimensions. Ball bearings are also very cost-effective.
Tapered roller bearings can withstand very high radial and axial loads. They are generally installed in pairs.
The cylindrical roller bearing is characterized by its high radial load carrying capacity.
Due to their design, toroidal roller bearings can simultaneously fulfill the function of a cylindrical roller bearing and a spherical roller bearing. They compensate for axial and angular misalignment by means of appropriately shaped roller tracks without increasing friction.
A needle roller bearing has needle-shaped rolling elements with a large length compared to the diameter of the rolling element.
Barrel bearings are primarily designed for high impact-type radial forces. They are suitable for compensating for misalignments.
Which type of bearing is right for you depends on what you want to use it for. The load and speed play an important role. Temperature, vibration, lubrication, installation and maintenance are equally important for making the right choice. Other important questions are the type of load that the bearing can support. Is it axial and radial forces, or is it a combination of different loads? The available space is also a decisive factor in selecting the right component. Let our specialist staff advise you.
