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 flex 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 (or follower) steady rest?\u003c\/summary\u003e\n\u003cp\u003eA fixed steady rest is locked in a fixed position on the lathe bed and supports the workpiece at a specific point. A traveling steady rest (or follower rest) is fixed to the longitudinal carriage and moves with the tool — it supports the workpiece at the same point relative to the tool, eliminating deflection during feeding. 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 workpieces that can be supported. Verify that your lathe model matches the one indicated.

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.\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 days shipping.
