EC1 electric cylinders from Kollmorgen (Radford, VA) provide a linear positioning alternative to pneumatic and hydraulic systems in applications requiring continuous thrust of ≤150 pounds. They feature controllable speed up to 0.325 m/s, accurate mid-stroke positioning, and position holding without power (with brake option). The cylinders deliver standard stroke lengths from 50 to 200 mm, and can handle maximum payload weight of 150 pounds at 100% duty cycle.

The cylinders feature repeatability to ±0.001” with lead accuracy to ±0.004 in./ft., with backlash of 0.015”. The compact 4.6” + stroke length × 1.89 × 3.25” footprint makes the EC1 suitable for space-restricted applications such as testing systems and test sample placement in medical applications, and for machines requiring precise, repeatable motion.
