Micro Linear Stage – KV™

For applications where a micro linear stage is required, Dover Motion’s KV™ series linear stage is one of our most compact products.

All Dover products can be configured to your specifications.Learn More


Each KV™ linear slide comes standard with end of travel limit sensors and a stepper motor (NEMA 17-frame motor size) to drive the lead screw. Two recirculating ball way rails along with the machined aluminum base provide stiff support for the moving payload.


The KV series micro linear stage has been employed in medical diagnostic instruments for sample motion. The KV was chosen due to it’s compact size and accurate performance which enabled the required performance to be achieved in benchtop sized instrument package.
