Selecting the right profile rail guide has a lasting impact on the performance and longevity of machines and equipment. But how do you find the right system among a wide range of options? Check out our blog to see what criteria really matter, from load types and accuracy requirements to environmental and installation conditions. We will show you a structured approach to help you make informed decisions and to optimize the performance of your applications over the long term.

The fastening mechanisms for linear shafts or guide shafts in mechanical systems require careful planning. Different shaft ends permit different mounting options. This article provides an overview of available shaft ends and answers the question of which shaft holders or shaft support options are available and where they are appropriate. As part of this, we also take a detailed look at the fixed and floating bearing types for shafts.

The tensile strength of steel and stainless steel is a critical parameter when it comes to the load-bearing capacity and safety of threaded joints. It is made up of two key parameters for steel screws based on which the tensile strength and the yield strength can be easily determined. But starting at a certain size, stainless steel screws and stainless steel nuts are marked with a letter-number combination (e.g. A4-80). The letter-number combination arranged in front of the hyphen assigns the screw so marked to a material group and steel group and thus provides information on the basic material properties of the screw. The number 80 to the right of the hyphen indicates the strength class. This article shows how to use the strength class of stainless steel bolts to determine their limits of use and provide an overview of the load-bearing capacity of typical strength classes.

The coefficients of expansion of materials play a crucial role in materials science. Coefficients of expansion describe how the dimensions of a material change under the influence of temperature fluctuations. This article provides a comprehensive introduction to the topic, including the basics of thermal expansion, influencing factors, and various measurement methods. We also compare typical expansion coefficients of material classes and explain their uses in various industries. Lastly, we address thermal stresses and ways to prevent damage from temperature differences in materials.

Springs are mechanical components that can store and deliver tension energy generated by the work used to tension, elongate or compress the spring in the form of deformation or tension energy. They are used in many applications and can be found in small electronic components as well as in large industrial machines. To ensure that a spring performs its function, it must be correctly designed. For this purpose, parameters such as the spring constant and the spring travel are calculated.

Sheet metal parts are used in our everyday life and in industry in a wide range of applications. In order for these manufactured sheet metal parts to be used interoperably, they must comply with certain accuracy standards and machining limits. These refer to specific parameters and tolerances with respect to width, length, thickness and geometric tolerances. The specifications must be taken into account when manufacturing sheet metal parts. The following examines various standards and limits in detail.

Pipe fittings are used to securely connect pipes, tubes, and hoses. They are used in pneumatics as well as in hydraulics and other fluid-carrying systems. However, suitable fittings and adapters are also available for pipes under vacuum. As an important component of these systems, it is essential that pipe fittings reliably and securely connect the components to be connected and permanently prevent liquids or gases from entering or exiting. This article introduces different types of pipe fittings and their ideal uses, and will help you choose the best pipe fitting for your application

Neodymium magnets are the strongest permanent magnets available and can produce very strong magnetic fields in the smallest of spaces. This property allows them to be integrated into a variety of devices and applications even when space is limited.

What makes neodymium magnets so strong, what applications are available, how they are made, and what to consider when using them is discussed in this article.
