LS-270 Linear Stage for Very High Loads
Robust Design with High Stiffness
- Travel ranges from 305 to 1016 mm (12 to 40")
- Excellent travel accuracy
- Max. velocity to 150 mm/s
- Load capacity to 1500 N
- Versions with linear measuring system
Reference-class linear stage
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.
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
Versions with direct position measurement
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.
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.
Application fields
Precision positioning in industry and research, high duty cycles.
