L-306 Compact Precision Z Stage

Product Description Specifications Downloads Quote / Order

Z stage with compact size due to folded drive with belt drive. Fits onto linear stages with M6 50 mm × 50 mm connection spacing (e.g., L-406).

2-phase stepper motor or closed-loop DC motor
Backlash-compensated ball screws

Incremental linear encoder (optional with stepper motor variants)
Noncontact optical reference and limit switches

Noncontact optical encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.

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.
