PWK presses are powered by compressed air at 6–8 bar: the piston automatically descends when the 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan the WK \/ PWK press press bearings and bushings?\u003c\/summary\u003e\n\u003cp\u003eYes. 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 coupling) the operation is safe and precise. For H7\/p6 couplings on steel: force ≈ 1–3 kN per mm of diameter.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the pressure gauge included as standard?\u003c\/summary\u003e\n\u003cp\u003eYes — all Bernardo WK and PWK presses include a pressure gauge for direct reading of the applied force in tons. Essential to avoid exceeding the maximum force of the coupling and prevent damage to pressed components.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre spare parts available?\u003c\/summary\u003e\n\u003cp\u003eOriginal Bernardo spare parts (gaskets, valves, pressure gauges) available with 3–5 working days shipping.

Versions up to 50T are fixed to the floor with standard M12 bolts.\u003c\/p\u003e\n\u003c\/details\u003e","brand":"Bernardo","offers":[{"title":"Default Title","offer_id":50695073235272,"sku":"06-1714","price":714.02,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Bernardo_PWK_20_F_Pressa_pneumatica_da_officina_20_ton.jpg?v=1759225362","url":"https:\/\/www.krollit.com\/products\/bernardo-press-pneumatic-pwk-20-f","provider":"Krollit","version":"1.0","type":"link"}
