Linear technology wiki

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.

In 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
