Separate, but related, concepts

High Accuracy AND High Repeatability

Accuracy is the ability of a linear actuator to reach a commanded position. if an actuator is highly accurate, it will exhibit a high degree of repeatability as well.

High Repeatability, but Lower Accuracy

Rebeatability is the ability of a linear actuator to reach the same position time after time. Repeatability is often what’s needed in an application rather than accuracy.

Lower Accuracy and Lower Repeatability

There are applications where positioning tolerances are wider. In those instances lower degrees of accuracy and repeatability are acceptable.
