Dimensional tolerances play a decisive role in mechanical design and directly influence the functionality and quality of machines, devices and other mechanical products. In mechanical design, tolerances refer to the permitted deviations from the ideal dimensions of a component or an assembly group. There are different fitting systems, such as the standard bore and standard shaft. For more information on tolerance classes, see our blog article “Tolerance Classes According to ISO 22081 and DIN ISO 2768”.

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.

From conveyor systems to robot-controlled production lines, cam followers enable the effortless movement of loads. A smooth process in industrial manufacturing and material handling depends on efficient and precise movement systems. Cam followers and roller followers play a decisive role here. Here, cam followers and roller followers ensure reliable guidance of linear movement. In this blog article, we dive into the basic knowledge of these components and examine their intended utilization in industrial practice.

Industrial surface treatment is a process in which the surface of a workpiece is machined to improve or change its mechanical, chemical or visual properties.

The retaining ring is one of the most important tools in construction. It is used to secure individual components and prevent axial movement. In this article, we will take a look at the different types of retaining rings, their features and their utilization.

Locating units play a central role in mechanics and are essential for designers in many different applications. In this article, we will review how locating units, their different types and their applications work.

Retaining rings are an important component of many machines and systems that serve to secure bearings, shafts, bolts and other components. A commonly used type of retaining rings is type C, which is manufactured according to the Japanese standard JIS. In this article, you will learn more about retaining rings C-type and the Japanese standard JIS.

Linear shafts are becoming increasingly popular in drive technology. They offer a high degree of precision in movement. Linear shafts have several advantages compared to traditional shafts, including high rigidity, high positioning accuracy, longer lifetime and also excellent control performance.

The friction coefficient is a physical variable derived from the field of tribology for the friction between two objects. The friction coefficient sets the force that occurs during friction (frictional force) in relation to the force with which the objects are pressed together (pressing force). The friction coefficient is thus an important parameter when examining material wear and sliding properties. This article explains the basics of the friction coefficient, its measurement methods and its applications in technology.
