It is essential when the workpiece's length-to-diameter ratio exceeds 4:1 (for a fixed steady rest) or 10:1 (for a traveling steady rest that accompanies the tool). Without a steady rest, long workpieces bend under cutting force, producing taper, vibrations, and non-cylindrical surfaces.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between a fixed steady rest and a traveling (rotary) steady rest?\u003c\/summary\u003e\n\u003cp\u003eA fixed steady rest clamps onto the bed in a fixed position and supports the workpiece at a specific point. A traveling steady rest (or follower rest) clamps onto the longitudinal carriage and accompanies the tool during movement — it always supports the workpiece at the same point relative to the tool, eliminating bending during feed. A traveling steady rest is necessary for turning very long workpieces where a fixed steady rest is not sufficient.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this steady rest compatible with my Bernardo lathe?\u003c\/summary\u003e\n\u003cp\u003eEach Bernardo steady rest is designed for the models indicated in the title. The workpiece diameter range (e.g., 50–590 mm) indicates the supportable workpieces. Verify that your lathe model matches the one indicated.

Lubricate the jaws with cutting oil or grease to reduce wear. Do not overtighten the jaws — they should support the workpiece without clamping it.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working day shipping.
