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 when the foot pedal is pressed, 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 bearings and bushings?
Yes. This is the main operation they are designed for: 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 couplings 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. Indispensable for not exceeding the maximum force of the coupling and avoiding damage to the pressed components.
Spare parts available?
Original Bernardo spare parts (seals, valves, pressure gauges) available with 3–5 working 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.
