Abstract
A bail compensating joint may include a threaded push rod, a ratchet in threaded connection with the push rod for rotational motion thereon, and a helical joint including a first bearing and a second bearing mounted on the ratchet for facilitating rotation of the ratchet. The second bearing is supported by an annular composite race member formed by a metal annular inner race member joined with a resiliently deformable annular outer member. In another embodiment of the bail compensating joint, a pair of spherical joints is disposed on opposite sides of the ratchet, the spherical joints supporting the respective first and second bearings.
