Ultra-compact linear actuator featuring micrometer-grade positioning accuracy (±0.1mm repeatability) through its dual adjustable cushioning system. The anodized aluminum body with hardened guide sleeves ensures wear resistance in high-cycle applications. Includes magnetic piston for position sensing compatibility.

Typical Applications:
  • Precision alignment in semiconductor wafer handling
  • High-speed sorting mechanisms (up to 5 cycles/sec)
  • Medical device assembly with cleanroom requirements
  • Robotic end-effector positioning systems
  • Pharmaceutical blister packaging machines
Installation note: For optimal performance, maintain 0.05-0.15mm clearance between rod and guide when using external linear bearings. Adjust cushion screws clockwise to increase damping force (max 1.5 turns from fully closed position).
