21000 SERIES SIZE 8 DOUBLE STACK STEPPER MOTOR LINEAR ACTUATORS Provide Enhanced Performance Over a Single Stack

Equipment designers and engineers now have an even more compact option for their motion applications. The Haydon 21000 Series Size 8 double stack stepper motor based linear actuator occupies a minimal 0.8” (21 mm) space and includes numerous patent pending innovations that provide customers high performance and endurance in a very small package. Three designs are available, captive, non-captive and external linear versions. The 21000 Series is available in a wide variety of resolutions — from 0.000098” (.0025 mm) per step to 0.00157” (0.04 mm) per step. The Size 8 double stack stepper motor based linear actuator delivers thrust of up to 17 lbs (75 N).

Assembly options include:

Incremental encoders, proximity sensors (captive types only), anti-backlash and custom nuts, and TFE coated lead-screws.
