Rollnut assemblies

Guided miniature rollnut assemblies control the accuracy of actuators in critical mechanisms and are for applications requiring exact and repeatable positioning and location, such as diagnostic equipment and laboratory instruments. The guided miniature rollnut consists of a miniature rollnut screw and nut assembly modified to include a linear bearing and guide rod supported by the same end plates that secure the rollnut screw. The resultant anti-rotational device does not require an outside guide system and ensures accurate positioning.
