Linear technology wiki
Technical terms explained simply
In the jungle of technical terms for linear technology, it is easy to lose track. We have therefore summarised all the important technical topics relating to our linear technology for you here. From the specifications of our materials to practical and research-based expertise. We also explain, for example, what the stick-slip effect or a linear system is.
If you still have questions, please don't hesitate to contact our linear technology expert Michael Hornung directly.
Your linear technology white paper
In our linear guide white papers, our experts share their practical experience and many years of research and development results. The white papers cover various topics in the field of linear bearing technology.
Frequently asked questions:
drylin® is a product range of lubrication-free linear plain bearings based on the principle of sliding instead of rolling. Tribologically optimised iglidur high-performance polymers are used as sliding surfaces. The drylin linear systems work in dry operation and are maintenance-free. Linear guides are available on rails or round shafts. In addition to the freedom from maintenance and lubrication, robustness and insensitivity to influences such as dirt, water, chemicals, heat or impacts are priorities.
A linear system is a complex design that allows machine parts to move along a route in space. These movements, known as translations, form the basis for a wide variety of machines and systems. Linear systems from various manufacturers are equipped with recirculating ball guides or skate wheel guides, which permit precise movement with low friction.
The linear rail systems offered by igus achieve similarly good values in terms of precision and friction and are characterised by their freedom from maintenance and lubrication, smooth operation and ease of assembly.
The stick-slip effect refers to the jerking movement of solid bodies moving against each other. This phenomenon occurs when the static friction of a moving body is significantly greater than its sliding friction.
More informationIn a hybrid linear bearing, plain bearings and roller bearings work together: integrated rollers achieve low drive forces while the sliding effect of the plain bearings protects against lateral forces. This combination results in the absorption of abusive forces:
1. Reduction of coefficient of friction
2. Reduction of the required drive force
3. System function without restricting the 2:1 rule
