This piece appears to be a possible mate to part A-1013. It is a heavy-duty bearing with a shaft coming out both sides. The structures on 1013 fit nicely with the green ends of this piece.
The bearing is pretty beat up and can come apart. We've taken great care to keep all the parts together.
Dimensions: 4.5" x 2" x 1.5"
