Linear technology wiki

drylin® is a programme 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 run in dry operation and are maintenance-free. Linear guides are available on a rail or round shaft basis. Besides the freedom from maintenance and lubrication, the focus is on the ruggedness and insensitivity to influences such as dirt, water, chemicals, heat or impacts.

A linear system is a complex construction that enables the movement of machine parts along a path in space. The function of a wide variety of machines and systems is based on these movements, known as translation. Many manufacturers' linear systems are equipped with recirculating ball bearing guides or roller guides, which enable precise running with low friction.

The linear rail systems offered by igus® achieve similarly good values in terms of precision and friction and are also characterised by being maintenance-free, lubricant-free, quiet running and easy to install.

In a hybrid linear bearing, a combination of plain 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 enables the absorption of abusive forces:

1. reduction of the coefficient of friction
2. reduction of the required drive force
3. function of the system without restriction of the 2:1 rule
