Linear ball bearings – Selection, installation and maintenance

Linear ball bearings are important components in many mechanical engineering applications. The function of linear ball bearings is to enable precise and low friction movement along an axis. This article provides important guidance on the selection, installation and maintenance of linear ball bearings, so you can be sure to find the right bearing for your application and get the most out of it.

Ball bearings – Load distribution for rolling bearings

Ball bearings and other rolling bearings are installed in numerous machines. The installed bearings transfer the radial or axial forces that occur to the machine housing and thus permit the use of various moving components. The forces that occur and the resulting load in the bearing must already be determined during the design process. The load distribution in the bearing and the matching contact point geometry is crucial for the expected service life, function and efficiency of the bearing. In this article, we will look at the load exerted on a rolling bearing and how contact surface geometry affects load distribution in the rolling bearing.

Sealing ball bearings – Seals, sealing washers and cover washers

Ball bearings are critical components in many machines and equipment and play a central role for low-friction movement of parts. Design-based protection of rolling bearings against overload and failure due to overheating, contamination and external influences is therefore one of the fundamental tasks of a design engineer. Ball bearings can for example be sealed or one can use roller bearings already sealed by the factory to achieve the longest possible service life. To minimize friction and wear, it is necessary to ensure that bearings are sufficiently lubricated. As part of maintenance, the ball bearings must therefore be checked and relubricated as needed. However, modern industrial technology increasingly uses self-lubricating or non-serviceable sealed rolling bearings, which are already equipped by the manufacturer with corresponding sealing elements and lubricant deposits.

Fit types and tolerances – An overview

Tolerances and fits are critical in the manufacturing industry. In the technical sense, tolerances define a permissible deviation from a defined property, such as a nominal dimension. They ensure that products and components meet the required quality standards.

Lubrication of Ball Screw Drives – Lubricants, Application Areas and General Information

Ball screws drives or recirculating ball spindles should never be used without lubrication, otherwise their functionality cannot be guaranteed and their service life will be shortened. Lubricants such as oil or grease may be used for lubrication. This article explains which lubricant is suitable for which reasons and how to optimally lubricate ball screws.

Differences between ball bearings and plain bearings – Which type of bearing is right for you?

Ball bearings and plain bearings are two basic types of bearings used in a variety of mechanical systems in mechanical engineering. The main task of bearings is to enable defined movements of components and thereby reduce friction as much as possible. Although both types of bearings have a common goal, there are fundamental differences in design, functionality and application. This blog article describes the most important differences between ball bearings and plain bearings.

Elements for securing axial bearings

In many industrial and mechanical applications, bearings are critical components that provide low friction, reproducible movement between moving parts, shafts, or axes. Depending on their installation location and function, these bearings must allow different degrees of freedom and be securely fixed. In addition to many other options, locking elements such as retaining rings or slotted nuts or shaft nuts are used to secure machine parts such as rolling bearings, bolts, or shafts against axial displacement.

Understanding bearing damage – Causes, failure mode and prevention

Rolling bearings are robust and reliable components in mechanical engineering and custom machine construction. Under certain conditions, however, bearing damage to these widely used machine elements can occur, usually resulting from unusual behavior during operation. In the worst case, bearing damage can result in a complete failure of the rolling bearings, which can result in unwanted downtime. Therefore, it is important to detect the first signs of rolling bearing damage early on and to remedy their causes. In this article, we discuss the symptoms of bearing damage, its causes and typical failure modes.
