M-238 High-Load Linear Actuator
Dynamic, High-Resolution Precision Drive with DC Motor and Direct Position Measuring
- Optional: Linear encoder for direct position measuring
- High load capacity to 400 N
- Travel range 50 mm
- Resolution to 0.1 µm
- Velocity to 30 mm/s
Reference-class linear drive
High-resolution, high-load linear actuator. Highly dynamic, closed-loop DC motors for high velocities.
High-quality components
Recirculating ball screw provides high velocity and long lifetime. Low-friction output shaft bearing can handle lateral forces to 100N. Nonrotating end piece for uniform motion prevents wobble, torque, and wear at the point of contact. Includes flat and spherical end piece for decoupling of lateral and tilt forces. Noncontact limit switches protect the mechanical system. A direction-sensing reference switch supports automation applications
Highly accurate position measuring with incremental linear encoder
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.
Application fields
Precision alignment, external drive element for guided systems.
