Bernardo PWK 100 F – 100 Ton Pneumatic Workshop Press
The Bernardo PWK 100 F is a top-of-the-range pneumatic press, suitable for industrial applications and workshops requiring extreme power. With a pressing force of 100 tons and a piston stroke of 300 mm, it is suitable for straightening axles and shafts, inserting or removing bushings, bearings, and bolts. The laterally movable cylinder with a travel of 245 mm ensures flexibility, while the automatic piston return simplifies continuous use. The welded steel structure ensures stability and long life even under extreme loads. The height-adjustable table, operated by a winch, allows for quick adaptation to different operational needs. Equipped with a standard foot pedal to leave hands free, the PWK 100 F, with its 664 kg weight, offers safety, reliability, and professional performance for heavy-duty work.

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 foot 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 press bearings and bushings?
Yes. This is the main operation they are designed for: inserting and removing 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 couplings on steel: force ≈ 1–3 kN per mm of diameter.
Is the manometer included as standard?
Yes — all WK and PWK Bernardo presses include a manometer for direct reading of the applied force in tons. Essential to avoid exceeding the maximum coupling force and damaging the pressed components.
Are spare parts available?
Original Bernardo spare parts (seals, valves, manometers) are available with 3–5 business day shipping. Customer support available in Italian.
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.
