SPIETH-designed guide bushings are round linear guiding elements for all fields of precise mechanical engineering.

These guide bushings are ideal for applications making use of the benefits of the slideway, such as damping properties, but require minimal guide play. For those advantages these guide bushings are successfully applied in guide frames, cylindrical carriage guides, on tailstock sleeves, press rams etc.

In addition to their linear movement, simultaneous rotary movements are possible. For reasons of lubrication technology, however, pure rotation as for sliding bearings is not allowed. High acceleration values are possible, as long as an adequate supply of lubrication is ensured.

Following practical examples will give an overview of different applications:
