PI LS-180
Travel ranges from 155 mm to 508 mm (6" to 20")
Max. velocity to 150 mm/s
Load capacity to 1000 N
Optional linear encoder for direct position measurement

Reference-class linear stage

Recirculating ball bearings for high travel accuracy and load capacity. Precision ball screw with 5 mm pitch. Stress-relieved aluminum base for highest stability. Noncontact inductive limit switches.

Drive types

  • Closed-loop DC servo motor with rotary encoder on the motor shaft
  • 2-phase stepper motor for high torque even at low velocities and high resolution

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.

Recirculating ball bearings

When carefully assembled, recirculating ball bearings are distinguished by a beneficial combination of high load capacity, lifetime, maintenance-free operation, and guiding accuracy. The moving part of the stages is supported by four preloaded linear ball bearing units which run on two guide rails. Each bearing unit is made up of two independent rows of circulating ball bearings.

Minimum incremental motion

In conjunction with the SMC Hydra controller, versions with stepper motor and integrated linear encoder achieve repeatable minimum incremental motion in the range of the sensor resolution. The same configuration achieves constant low velocities of a few sensor increments per second.
