Bernardo Foot-operated Shrinker and Stretcher SS 150 F
The Bernardo Foot-operated Shrinker and Stretcher SS 150 F is a professional sheet metal working machine, designed for precise shrinking and stretching of metal panels and profiles. It allows working with steel up to 1.5 mm and aluminum up to 1.8 mm, with a throat depth of 150 mm, which provides greater flexibility on medium-sized workpieces compared to more compact models. Thanks to its foot-operated control, the operator can work with both hands free to correctly position and guide the sheet metal, improving precision and safety. Supplied with two separate attachments (one for stretching and one for shrinking), it eliminates the need to change tools during processing. With a low weight (20 kg) and stable structure, it is the ideal choice for body shops, restorers, and craft workshops.

Frequently Asked Questions
What does a shrinker do and what does a stretcher do?
The shrinker compresses the metal fiber at the edge, shortening it and creating a concave curve. The stretcher elongates the fiber by expanding it, creating a convex curve. Alternating between the two functions allows for complex shapes to be achieved on thin sheet metal without wrinkles or tears. An essential tool for bodyworkers, boat builders, and vehicle restorers.
What sheet metal thicknesses can the Bernardo Foot-operated Shrinker and Stretcher work with?
Bernardo shrinker/stretchers typically work with steel up to 1.2–2.0 mm and aluminum up to 1.5–2.5 mm depending on the model. Check the specific limits in the technical table of the Bernardo Foot-operated Shrinker and Stretcher. Exceeding the limits causes damage to the tools and irregular deformation of the workpiece.
What is the difference between lever, foot-operated, and motorized versions?
The lever (Pro) version is manual: the operator activates the lever with both hands, ideal for occasional work. The foot-operated (FD/F) version operates the machine with the foot, freeing both hands to hold and guide the workpiece — more comfortable for repetitive tasks. The motorized or electric version automates the complete cycle for series production.
Do the jaws wear out? Are spare parts available?
Yes. The jaws of shrinker/stretchers wear out after prolonged intensive use. Original Bernardo spare jaws are available with 3–5 business days shipping. Replacement does not require special tools.
Does it also work on copper and brass?
Yes. Copper and brass are more ductile materials than steel: the actual capacity is higher than for mild steel. For specific alloys, check thickness limits with Krollit. Customer support in Italian available.
