Reference-class Z stage

Extremely accurate and reliable positioning. Crossed roller guides for smooth feed at high loads. Stress-relieved aluminum base for highest stability. Drive variants with DC motor and 2-phase stepper motor. Noncontact limit switches.

Highly accurate position measuring with incremental linear encoder

Noncontact optical linear encoders measure the actual position directly at the motion platform with the greatest accuracy so that nonlinearity, mechanical play or elastic deformation have no influence on position measuring.

Crossed roller guide

With crossed roller guides, the point contact of the balls in ball guides is replaced by line contact of the hardened rollers. Consequently, they are considerably stiffer and need less preload, which reduces friction and allows smoother running. Crossed roller guides are also distinguished by high guiding accuracy and load capacity. Force-guided rolling element cages prevent cage creep.

Application fields

Industry and research, e.g., semiconductor inspection, fiber alignment.
