Bernardo PWK 50 F – Pneumatic Workshop Press 50 ton
The Bernardo PWK 50 F is a high-power pneumatic press designed for intensive work in workshops and maintenance companies. With a pressing force of 50 tons and a piston stroke of 200 mm, it allows for straightening, assembly, bending, and pressing operations on large components. The cylinder, which can be moved laterally by 240 mm, ensures maximum versatility, while the automatic piston return facilitates its use. The height-adjustable work table with a winch makes configuration changes quick. The welded steel structure ensures stability and long durability, while the standard foot pedal keeps hands free for workpiece handling. Thanks to its robust and compact design, with a weight of 292 kg, the PWK 50 F is the choice for mechanical workshops and maintenance departments that need a powerful and reliable pneumatic press.

Frequently Asked Questions
What is the difference between WK (manual) and PWK (pneumatic)?
WK presses have manual hydraulic actuation — the operator pumps the lever to pressurize the cylinder. PWK presses are operated by compressed air at 6–8 bar: the piston automatically descends by pressing the pedal, with constant speed and force regardless of the operator. PWK presses are more productive for repetitive series operations; WK presses are more economical and do not require a pneumatic system.
Can the WK / PWK press press bearings and bushings?
Yes. This is the main operation they are designed for: insertion and removal of bearings, bushings, plain bearings, pins, and inserts. With the correct force (calculated based on the diameter and interference of the fit) the operation is safe and precise. For H7/p6 fits on steel: force ≈ 1–3 kN per mm of diameter.
Is the pressure gauge included as standard?
Yes — all WK and PWK Bernardo presses include a pressure gauge for direct reading of the applied force in tons. Essential for not exceeding the maximum force of the fit and avoiding damage to pressed components.
Are spare parts available?
Original Bernardo spare parts (gaskets, valves, pressure gauges) available with 3–5 business days shipping. Customer support in Italian available.
What foundation does it require?
WK and PWK presses do not require a special foundation — a standard industrial floor (15–20 cm concrete) is sufficient. Versions up to 50T are fixed to the floor with standard M12 bolts.
