Concentric yoke shafts have a threaded stud that extends centrally from the inner race of a compatible yoke cam follower to secure the bearing to a component. They are useful in general purpose applications to convert rotating motion to linear motion.

Eccentric yoke shafts allowing for fine adjustments to the positioning of compatible yoke cam followers by turning the shaft. Eccentric yoke shafts reduce system downtime caused by re-aligning the yoke cam follower or re-machining of the shaft's mounting hole position.
