A steady rest is a support that attaches to the lathe bed and supports long or heavy workpieces during machining, preventing deflection and vibrations. It is essential when the length/diameter ratio of the workpiece exceeds 4:1 (for a fixed steady rest) or 10:1 (for a traveling steady rest that moves with the tool). Without a steady rest, long workpieces will deflect under cutting forces, causing taper, vibrations, and non-cylindrical surfaces.

A fixed steady rest locks onto the bed in a fixed position and supports the workpiece at a specific point. A traveling steady rest (or follow rest) attaches to the carriage and moves with the tool — it supports the workpiece at the same point relative to the tool, eliminating deflection during advancement. A traveling steady rest is necessary for turning very long workpieces where a fixed steady rest is not sufficient.

Each Bernardo steady rest is designed for the models indicated in the title. The workpiece diameter range (e.g., 50–590 mm) indicates the workpieces that can be supported. Verify that your lathe model matches the one indicated. Customer support in Italian available.

The steady rest must be centered with respect to the lathe's axis: mount the workpiece between centers, place the steady rest jaws on the rectified diameter or on an already turned area (not on the raw material) and adjust the jaws until light contact. Lubricate the jaws with cutting oil or grease to reduce wear. Do not tighten the jaws forcefully — they should support the workpiece without clamping it.
