EC3 Series

Danaher Motion Image

The EC3 Series of Electric Cylinder systems are a robust linear motion package for moderate to heavy thrust loads.  Screw types yield quiet operation, low backlash, and high accuracy with a variety of motor to screw reduction types.  Bearing and drive housings are made of durable construction material with optional environmental capabilities to meet most moisture or contaminant conditions.  Special design minimizes the need for routine maintenance.

Available Motors:

  • T32x Kollmorgen Hybrid Stepper motor (P7000 drive recommended)
  • AKM23C, 23D, 42E, 42G Kollmorgen Brushless AKM Servomotors 
  • NEMA 23, 34, 42, 52 custom motor mount
