Bernardo WK 20 FH Pro – Professional 20 Ton Workshop Press
The Bernardo WK 20 FH Pro is a professional workshop press with a 20-ton capacity, designed for high precision and reliability in straightening, pressing, bending, and assembly operations involving gears, washers, and bushings. It features a laterally sliding cylinder, allowing versatile work across the entire bed width, and an automatic piston return via a return spring. Piston advancement can be achieved using a hydraulic foot pedal or a manual pump, making the press practical and suitable for various applications. A large, easy-to-read pressure gauge provides clear indication of the pressing force. Thanks to the height-adjustable table with locking pins, the robust welded steel construction, and self-regulating hydraulics, the WK 20 FH Pro is suitable for professional workshops requiring reliability and long service life.

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 automatically descends when the foot pedal is pressed, 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 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 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 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 fit and avoiding damage to the pressed components.
Are spare parts available?
Original Bernardo spare parts (seals, valves, pressure gauges) are 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.
