Rotary Motion

Industrial value chains are increasingly focused on manufacturing and maintenance costs. Maintenance costs represent a large portion of the ongoing operating costs of a system. High-quality and maintenance-friendly components help to keep these costs as low as possible while ensuring the required quality. However, planning and design does not always have to rely on the most expensive component. Using ABC analysis, products and components can be classified as ABC parts based on their value share and their importance in the value chain. The most cost-efficient articles are the so-called C articles or C-parts. These have a small share of value, but are required in large numbers. These parts have great potential to reduce costs. It’s worth taking a closer look. For many applications, cost-efficient items are a good alternative to expensive items. However, a low price does not have to mean a loss in quality; the application range of cost-efficient items may only be limited, for example, by the often lower precision. This article will show you how to use C-parts such as plain bearings in a cost-efficient manner, and how to select them purposefully, while at the same time ensuring quality.

Rotary shafts are an essential element of modern mechanical engineering. Rotary shafts transfer rotary motion. They can be manufactured from different materials, which are selected specifically to match the application. The materials include stainless steel, corrosion-resistant steel, and steel.

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.

When shafts and axes are coupled in a machine, there is always a misalignment between the centre points of the shafts. The coupling compensates for this alignment error by the elasticity of the component or mechanical element during rotation or power transmission. Whether you are an experienced engineer or just diving into the world of mechanical engineering, this article gives you a comprehensive insight into the basics of couplings.

This blog article provides an introduction on how couplings work and the different types in use today.

Bearings are an essential component for fixing and guiding rotary and torsion shafts. They can have a major impact on the service life of your system and machines, which is why it is important to make the right choice. This article describes which bearings are best suited for rotary and torsion shafts and what you need to consider when selecting them.
