Which Conforti hydraulic cylinders are right for presses and shearing machines?

For presses and shearing machines we recommend the heavy-duty DP series to ISO 6022 (250 bar), which is resistant to impact loads. For closed-loop positioning and stroke control of a press's secondary movements, the TP servo series is used.

How do the cylinders handle the impact loads during shearing?

The ISO 6022 design (DP / TP) is dimensioned for impact: a hardened chromed rod, a bronze double guide that absorbs side loads, and adjustable end-of-stroke cushioning that dampens the shock at the end of the stroke and protects the machine.

What operating pressure do the cylinders for pressing offer?

The DP / TP series operate at 250 bar and are tested at 375 bar to ISO 10100. Higher pressure means more force for the same bore — ideal for compact, high-output presses.

What is the end-of-stroke cushioning for on press cylinders?

Adjustable cushioning with a quick-start system slows the piston at the end of the stroke, prevents mechanical shocks and noise, and extends the life of both the cylinder and the press. It is set with a screw according to the load being decelerated.

Can a control valve be mounted directly on a press cylinder (CETOP)?

Yes, the cylinders can be fitted with a CETOP plate to the ISO 4401 interface (NG6 / NG10) for direct valve mounting — fewer hoses and a more compact press hydraulic system.

How fast can you deliver press cylinders and in which currency do you invoice?

Standard delivery is 2–14 working days, with urgent production within 48 hours. Quotations and invoicing are in EUR.

Which rod should I choose for impact pressing and shearing?

For impact loads we recommend a hardened chromed rod (RRH) and a larger rod diameter for higher buckling stiffness. The bronze double guide absorbs side loads during shearing and protects the seals.

How is the buckling strength of a rod checked on a press?

Buckling is calculated from the stroke length and the type of mounting (stroke factor FC) using Euler's formula. For long strokes and pushing forces the configurator checks buckling and warns you if a larger rod or a different mounting is needed.

Hydraulic cylinders for presses and shearing machinesSmaller presses and secondary movements · DP / TP (ISO 6022)

For hydraulic presses, shearing and blanking machines, punching, press-brake, briquetting and scrap presses, the heavy-duty double-acting hydraulic cylinders DP / TP to ISO 6022 (nominal pressure 250 bar, test pressure 375 bar to ISO 10100, bore Ø 50–200 mm, stroke up to 6000 mm, reference force 730 kN) come into their own — on smaller presses and demanding secondary movements (ejectors, hold-downs, feeds and positioning). They handle high forces over a short stroke and cyclic shear loads; adjustable end-of-stroke cushioning protects the machine frame from impact when the material is punched through. For closed-loop positioning and stroke control of a press's secondary movements, the TP servo series follows on, with integrated position feedback. Supplied by hydraulika.store, an authorised distributor of Conforti Oleodinamica for the Czech Republic, Slovakia and the EU — with an online configurator, free CAD models and delivery within 14 working days.

Need closed-loop positioning on a press? For secondary press movements with position control and synchronisation, the TP servo series with integrated feedback is used. Suitable where simple end-position sensing is not enough and closed-loop stroke control is required. More about TP servo cylinders →

Impact when punching through material? On shearing and punching presses, choose the heavy-duty DP series (ISO 6022, 250 bar) with adjustable end-of-stroke cushioning (variant K at both the front and rear). It dampens the shock at the end of the stroke, protects the press frame and extends the cylinder's life. View DP cylinders →

When to choose DP or TP servo?

Heavy-duty DP (ISO 6022, 250 bar) has thicker rods for smaller presses and demanding secondary press movements — shearing and punching operations — with end-of-stroke cushioning against impact. TP servo is used for closed-loop positioning and stroke control of secondary movements with precise continuous position measurement. For lighter secondary movements around a press — ejectors, hold-downs, feeds and positioning — the cheaper flange-mounted HD / HK series (ISO 6020/2, 210 bar) without the double bronze guide is sufficient.

Industrial applications

Where press cylinders are most often used

Hydraulic presses, shearing and blanking machines, punching and press-brake presses, briquetting and scrap presses — wherever high force over a short stroke, repeatability and durability under cyclic operation are decisive. The heavy-duty ISO 6022 series (DP) with end-of-stroke cushioning against impact handles demanding cyclic loads; TP servo adds closed-loop positioning and stroke control of a press's secondary movements.
