Reference-class linear drive

High-load precision linear actuator. Highly dynamic, closed-loop DC motors for high velocities. Vacuum-compatible versions to 10-6 hPa are available

 

 

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 point switch supports automation applications

 

Variants of position measurement

  • High-resolution rotary encoder
  • Direct metrology: noncontact linear encoder measures the current position with 0.1 µm resolution and removes inaccuracies in the drivetrain
