1. A trunnion roller thrust measurement assembly, comprising:
a trunnion roller assembly, including:
a roller configured to provide rotary support of a rotary drum;
a shaft attached to the roller, the shaft being aligned with an axis of rotation of the roller; and
a bearing housing configured support an end of the shaft;
a thrust measurement assembly, including:
a bearing housing end cap attachable to an end of the bearing housing; and
a set of thrust sensors disposed on an outer surface of the bearing housing end cap,
wherein the set of thrust sensors are configured to sense a thrust force exerted on the bearing housing end cap by an axial displacement of the shaft, and
wherein an adjustment mechanism is utilized to skew the roller based on the sensed thrust force; and
a distance sensor disposed on the bearing housing end cap,
wherein the distance sensor is configured to sense a distance between the end of the shaft and a thrust bearing disposed on the bearing housing end cap.
