ABSTRACT:
A true centering steady rest for rotatably supporting an elongated cylindrical workpiece for a metal working operation on the outer diameter of the workpiece, such as a grinding operation. The steady rest includes a housing in which is slidably mounted a pusher arm carrying a workpiece center wear pad. A pair of side arms are slidably mounted on said pusher arm. Each side arm carries a replaceable wear pad engageable with a workpiece at a point in the range from 90.degree.-140.degree. from the center wear pad. The center and side wear pads are moved into operative engagement with a workpiece when the pusher arm is moved toward the workpiece, and they are disengaged from the workpiece when the pusher arm is moved away from the workpiece.
