The ZBX Series anti-backlash assembly from Kerk Motion Products (Hollis, NH) offers a linear actuator for design operations requiring precise positional accuracy and repeatability, at minimal cost. The inherent damping qualities of the ZBX design suit it for vertical applications requiring noise or vibration control.
Kerk’s standard ZBX unit utilizes a patented self-lubricating polyacetal nut that is radially preloaded on a 303 stainless steel screw. The assembly offers consistent torque and repeatability when traversing in either direction through its load transfer capability.
