HPS-170 High-Precision Linear Stage for Heavy Loads

PI HPS-170
Travel ranges from 52 to 205 mm (2 to 8")
Max. velocity to 100 mm/s
Load capacity to 35 kg
Optional linear encoder for direct position measurement

Reference-class linear stage

High travel accuracy and load capacity due to crossed roller guides. Precision ball screw. Stress-relieved aluminum base for highest stability. Mechanical 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.

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.

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.
