The patented Kerk ZBX Series anti-backlash assembly offers an effective linear actuator for design operations requiring precise positional accuracy and repeatability, with minimum cost.

The standard ZBX unit utilizes a patented self-lubricating polyacetal nut radially preloaded on 303 stainless steel screw.

The ZBX assembly, through its unique transfer of loads, offers exceptional torque consistency and repeatability when traversing in either direction. The inherent damping qualities of the ZBX design make it ideally suited for vertical applications requiring noise or vibration control.

End machining to customer specifications and Kerkote® TFE screw coating are optional, as are designs for special operating configurations or environments.
