Abstract: A journal-coupler includes a first portion with a first opening and a second opening, a first pair of flanges and a first connecting portion. A second portion is removably connected to the first portion. The second portion includes a third opening and a fourth opening, a second pair of flanges and a second connecting portion. An upper bearing portion and a lower bearing portion removably connected to the upper bearing portion are included. The first connecting portion and the second connecting portion combine as an enclosed torque tube portion and connect over a first torque tube and a second torque tube. The lower bearing portion includes a pier insert portion with fastening slots, a first prong, and a second prong. The journal-coupler sustains a continuous electrical ground path between the first portion, the first torque tube, the second torque tube and the second portion.

Abstract: A single-axis tracker system includes a bearing race including a pair of flanges that each include a slot that limits north-south movement of at least one torque tube that is disposed within the bearing race. A journal-coupler removably connects to the bearing race. A moveable ganged bearing lock holds the at least one torque tube in place while in a stow position.

Abstract: A journal-coupler includes a first portion including a first pair of flanges and a first coupler portion and a second portion that is removably connected to the first portion.
