LS-270 Linear Stage for Very High Loads

Robust Design with High Stiffness

LS-270 Linear Stage for Very High Loads

Product Description Specifications Downloads Quote / Order

High travel accuracy and load capacity due to crossed roller guides with long lifetime. Precision ball screw with 5 mm pitch. Stress-relieved aluminum base for highest stability. Noncontact inductive limit switches.

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

Integrated linear encoder, mounted between the guides. Direct position measurement of the motion platform eliminates the influence of mechanical play and hysteresis in the drivetrain on the positioning precision.

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.

Precision positioning in industry and research, high duty cycles.
