Abstract
A device for use downhole in a drill string includes a body that is cylindrical. The body has a longitudinal axis and top and bottom threads that can couple the body to other elements of the drill string. A radial shock absorber is coupled to an exterior of the body. The radial shock absorber has a piston with a piston axis. A portion of the piston extends to an exterior of the body. The piston can move along the piston axis between a retracted position and an extended position. In addition, a spring is located between the body and the piston. The spring can bias the piston, along the piston axis, radially outward relative to the longitudinal axis of the body.
