complementary to maintain the fixed distance contact on the other side of the cam. Another
shortcoming of the single-disk yoke cam is that any wear produces clearance, which results
in poor action at moderate to high speeds. Two roller followers may be utilized in lieu of
surfaces to reduce this wear and detrimental backlash. The yoke cam is rarely utilized.
The conjugate, complementary, or double-disk cam is one having dual radial disks,
each in contact with a roller on the follower. Figure 1.11 shows this type with an oscil-
