Bernardo WK 15 TH Pro – Professional Workshop Press 15 tons
The Bernardo WK 15 TH Pro is a professional workshop press with a 15-ton capacity, suitable for straightening, pressing, bending, and assembling gears, bushings, and washers. The machine features a laterally sliding pressure cylinder, which allows for processing across the entire width of the table. Automatic piston return is ensured by an integrated return spring, while the height-adjustable table with locking pins offers maximum flexibility in applications. The welded steel structure ensures robustness and stability, while the large pressure gauge allows for precise monitoring of the exerted pressing force. Compact in size, at 74 kg, it is the versatile choice for craftsmen, mechanical workshops, 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 foot 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: inserting and removing 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 the pressed components.
Are spare parts available?
Original Bernardo spare parts (seals, 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.
