Bernardo WK 20 FH - Workshop Press 20 Ton

Bernardo WK 20 FH – 20-ton Workshop Press

The Bernardo WK 20 FH is a robust workshop press with a 20-ton pressing force, suitable for straightening, pressing, bending, and assembling gears, bushings, and washers. It features a single-stage manual hydraulic pump and automatic piston return, with the standard foot pedal included for practical and safe piston advancement. The work table is height-adjustable with locking pins, allowing it to adapt to various processes and workpiece sizes. The welded steel structure ensures stability and long-lasting durability even with intensive use. Thanks to the integrated pressure gauge, pressure can be monitored simply and precisely. At 94 kg, the WK 20 FH represents a solid, efficient press offering the best value for money for mechanical workshops, artisans, and maintenance laboratories.

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. PWKs are more productive for repetitive serial operations; WKs are more economical and do not require a pneumatic system.

Can the WK / PWK press bearings and bushings?

Yes. This is the main 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 preventing damage to the pressed components.

Spare parts available?

Original Bernardo spare parts (seals, valves, pressure gauges) available with 3–5 working day shipping. Customer service 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.
