Bernardo DP 8 Rack and Pinion Manual Press
The DP 8 rack and pinion manual press is designed for heavy-duty work in workshops and maintenance departments. Made from professional-grade grey cast iron, it ensures strength, stability, and long service life. With a maximum workpiece height of up to 450 mm and an effective force of over 1.7 tons, this press is suitable for straightening, pressing, bending, and for mounting gears, washers, bushings, and bearings.
The adjustable 780 mm long lever allows the operator to adapt the effort required according to needs. The large diameter rotating table, equipped with openings of different sizes, allows for versatile and safe use. Pre-drilled with fixing holes, it can be stably mounted on a workbench to ensure precision and safety.

Frequently Asked Questions
What is the difference between WK (manual) and PWK (pneumatic)?
WK presses have manual hydraulic actuation — the operator pumps the lever to pressurize the cylinder. PWK presses are air-powered at 6–8 bar: the piston automatically descends by pressing the 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 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 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 joint and avoiding damage to pressed components.
Are spare parts available?
Original Bernardo spare parts (seals, valves, pressure gauges) are available with 3–5 business day 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.
