Which Conforti hydraulic cylinders for presses and shearing machines?

For presses and shearing machines we recommend the heavy-duty DP cylinders to ISO 6022 (250 bar), which resist shock loading. For controlled positioning and travel regulation of auxiliary press motions, the TP servo series is used.

How do the cylinders cope with shock loading during shearing?

The ISO 6022 design (DP / TP) is dimensioned for shocks: a hardened chrome-plated rod, double bronze guides absorbing side forces, and adjustable end-of-stroke cushioning that damps the shock at the end of the stroke and protects the machine.

What operating pressure do the pressing cylinders offer?

The DP / TP series operate at 250 bar and are tested at 375 bar to ISO 10100. A higher pressure means more force from the same bore — suitable for compact, powerful presses.

What is end-of-stroke cushioning for on pressing cylinders?

Adjustable cushioning with a quick start slows the piston at the end of the stroke, prevents mechanical shocks and noise and extends the service 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 pressing cylinder (CETOP)?

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

How quickly can you deliver cylinders for presses?

Normally 2–14 working days, with production within 48 hours for urgent orders.

Which rod should I choose for shock pressing and shearing?

For shock loading we recommend a hardened chrome-plated rod (RRH) and a larger rod diameter for higher buckling stiffness. The double bronze guides absorb the side forces during shearing and protect the seals.

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

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

Hydraulic Cylinders for Presses and Shearing Machines

Smaller presses and auxiliary motions · DP / TP (ISO 6022)

For hydraulic presses, shearing and blanking machines, punching, press-brake, briquetting and scrap presses, the heavy-duty DP / TP double-acting hydraulic cylinders to ISO 6022 are the choice (nominal pressure 250 bar, tested at 375 bar to ISO 10100, bore Ø 50–200 mm, stroke up to 6000 mm, reference force 730 kN) — for smaller presses and demanding auxiliary motions (ejectors, blank holders, feeds and positioning).

They handle high forces over a short stroke and cyclic shear loading; the adjustable end-of-stroke cushioning protects the machine frame against the shock of material break-through. For closed-loop controlled positioning and travel regulation of auxiliary press motions, the TP servo series with integrated position measurement takes over.

For shearing and punching presses choose the heavy-duty DP series (ISO 6022, 250 bar) with adjustable end-of-stroke cushioning (variant K, front and rear). It damps the shock at the end of the stroke, protects the press frame and extends the cylinder’s service life. View DP cylinders →

Three solutions for presses and shearing machines

When to choose a heavy-duty cylinder or a servo cylinder?

The heavy-duty DP (ISO 6022, 250 bar) has stronger rods for smaller presses and demanding auxiliary press motions — shearing and punching operations — with end cushioning against shocks. The TP servo serves controlled positioning and closed-loop travel regulation of auxiliary motions with precise continuous position measurement. For lighter auxiliary motions around the press — ejectors, blank holders, feeds and positioning — the cheaper flange HD / HK series (ISO 6020/2, 210 bar) without double bronze guides is sufficient.

Industrial applications

Where press cylinders are most often used

Hydraulic presses, shearing and blanking machines, punching and press-brake machines, briquetting and scrap presses — wherever high force over a short stroke, repeatability and service life in cyclic duty are decisive.

High force over a short stroke, repeatability and service life in cyclic duty.

DP: Smaller presses, auxiliary motions, shearing and punching operations — ISO 6022 at 250 bar, stronger rods and adjustable end cushioning against the shock of material break-through.
TP: Controlled positioning and closed-loop travel regulation of auxiliary motions — the heavy-duty envelope plus a magnetostrictive position sensor.
HD / HK: Ejectors, blank holders, feeds and positioning around the press — the ISO 6020/2 flange design at 210 bar as a cheaper choice without double bronze guides.
