Bernardo English Wheel RSM 1040 for Sheet Metal Working
The Bernardo English Wheel RSM 1040 is designed for shaping and forming sheet metal, suitable for bodywork, restoration, prototyping, and artisan workshops. With a throat depth of 1080 mm and an internal height of 760 mm, it allows for working on large panels. It is suitable for thicknesses up to 1.2 mm (steel, 400 N/mm²) and up to 1.5 mm for aluminum. The main wheel, Ø 180 x 75 mm, combined with the 5 interchangeable lower rollers included, allows for a wide range of curvatures and precise work. Thanks to the quick-release mechanism of the lower wheel, changing rollers is simple and fast. With a robust structure and a weight of 135 kg, it ensures stability and precision during operations. An indispensable machine for those seeking professional results in sheet metal working.

Frequently Asked Questions
What is an English wheel and what is it used for?
The English wheel is a machine for forming sheet metal with a double curvature: two opposing rollers (upper and lower) press the sheet metal, which is moved back and forth, progressively creating curved surfaces such as fenders, hoods, body panels, and boat hulls. It is the fundamental machine for artisanal bodywork and the construction of aluminum components with complex surfaces.
What is the difference between RSM 450, RSM 560, RSM 700, RSM 830, RSM 960, RSM 1040, and RSM 1100?
The number indicates the effective working width in mm — that is, the maximum distance between the centers of the rollers where the sheet metal can be worked. The RSM 450 (450 mm) is the most compact for small pieces; the RSM 1100 (1100 mm) is the largest for standard size body panels. The choice depends on the maximum width of the panels to be formed.
What sheet metal thicknesses can the RSM series work with?
For aluminum: up to 1.5–2.0 mm depending on the model. For mild steel: up to 1.0–1.5 mm. For thicker sheets, the required force increases significantly — check the specific model limits in the technical table. The RSM 1100 × 1.5 indicates a width of 1100 mm with a 1.5-inch lower roller.
Are replacement rollers available?
Original spare parts available with 3–5 business day shipping. Customer support available in Italian.
Is specific training required to use an English wheel?
Yes. Forming with an English wheel requires technique and practice: the tension of the sheet metal, the direction, and the pressure of the passes determine the final shape. An inexperienced operator can create irregular undulations that are difficult to correct. It is advisable to start on scrap material to gain confidence before working on definitive pieces.
