Bernardo PWK 75 F – 75 ton Pneumatic Workshop Press
The Bernardo PWK 75 F is a high-capacity pneumatic press, designed for professional and heavy-duty workshop use. With a pressing force of 75 tons and a piston stroke of 250 mm, it ensures high performance for straightening, bending, pressing, and complex mechanical assembly. The cylinder, laterally movable by 260 mm, offers ample flexibility, while the automatic piston return facilitates continuous use. The bed adjustment via a winch and 8 height positions ensure adaptability to various operational needs. The standard foot pedal allows for hands-free operation, increasing safety and productivity. Built with a robust welded steel frame and weighing 426 kg, the PWK 75 F is synonymous with stability and long-lasting durability. It is suitable for mechanical workshops, maintenance departments, and companies requiring a powerful and reliable pneumatic press.

Frequently Asked Questions
What is the difference between WK (manual) and PWK (pneumatic)?
WK presses have manual hydraulic operation — the operator pumps the lever to pressurize the cylinder. PWK presses are operated by compressed air at 6–8 bar: the piston descends automatically by pressing the pedal, with constant speed and force regardless of the operator. PWK presses are more productive for repetitive serial operations; WK presses are more economical and do not require a pneumatic system.
Can the WK / PWK press bearings and bushings?
Yes. This is the primary operation for which they are designed: insertion and removal of bearings, bushings, plain bearings, pins, and inserts. With the correct force (calculated based on the diameter and interference of the coupling), 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 Bernardo WK and PWK presses include a pressure gauge for direct reading of the applied force in tons. Essential for not exceeding the maximum force of the coupling and avoiding damage to the pressed components.
Are spare parts available?
Original Bernardo spare parts (seals, valves, pressure gauges) available with 3–5 business day shipping. Customer support in Italian available.
What foundation is required?
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.
