Abstract: According to one embodiment, a pitch link includes a first link, a second link coupled to a first end of the first link, a third link coupled to a second end of the first link opposite the first end, and a first bearing housing having a first bearing and a second bearing housing having a second bearing. The first bearing housing is removably coupled to the second link. The second link separates the first bearing housing from the first link. The second bearing housing is removably coupled to the third link. The third link separates the second bearing housing from the first link.

Abstract: A laminated elastomeric bearing has layers of elastomeric material and layers of metal. A tab is located on a periphery of one of the layers of metal and protrudes from the bearing. A thermoelectric device is coupled to the tab, and heat generated within the bearing during use is conducted to the tab and to the thermoelectric device, allowing for measurement of the heat.
