Franke Linear Systems are the best solution when it comes to speed and lightweight construction.

They owe their outstanding functionality to the tried and true 4-point contact. Their modular construction allows us to individually modify the Linear Systems to deliver precisely what you need.

Wire raceways made of steel or non-corrosive inserted in the aluminium body ensure high resilience and load capacity. The wire raceway is aligned with the width of the rollers and keeps them precisely on track.

  •  Wire Race Bearings and Linear Systems

Franke is the inventor of the wire race bearing and the world leader in the development and manufacture of lightweight movement systems both rotational and linear.

  •  Franke Principle

Franke wire race bearings are based on a simple but ingenious principle: individual race rings made of wire are provided with a raceway which is exactly adapted to the diameter of the rolling elements. The rolling process does not take place directly between rolling elements and enclosing construction, but on the four open races. This principle allows the free design of the enclosing construction in terms of geometry and choice of materials. The Franke wire race bearing principle also offers the advantage of free choice of material for the housing. The use of lightweight materials such as aluminum, plastic or carbon allows significant weight savings. The drive system can also be made smaller, resulting in energy savings of up to 30%.

The 4-point contact principle permits a maximum degree of flexibility and hence lays the ideal foundation for individual product solutions. Our customers are at liberty to choose whichever material, geometry, size, bore pattern, gear and sealing they require. An extremely broad range of materials can also be used for the mating structure. Our product solutions are always tailored to suit the specific application. From the concept to prototype construction and on to extensive test series testing, we engage at all times in close cooperation with our customers. This permits the manufacture of individual pieces and also series production.
