An improved scotch yoke has a means for absorbing sideward thrust. It includes a rod extending in a first direction through a hole in the yoke housing. A yoke arm in the housing is pivotable about an axis and extends in a second direction that intersects the first direction. Projection means, preferably on a member on the rod, extend through a slot in the yoke arm to link the rod with a means for absorbing sideward thrust to minimize bowing and twisting in the yoke arm and the rod. Movement of the rod slides the member in the first direction and pivots the yoke arm about the axis.
