What does it mean that the hydraulic cylinders comply with ISO 6022?

ISO 6022 defines the dimensions, mountings and design criteria for hydraulic cylinders with an operating pressure of 250 bar. It thereby ensures mutual interchangeability and compliance with international standards.

What is the operating pressure of ISO 6022 hydraulic cylinders?

ISO 6022 hydraulic cylinders operate at 250 bar. This delivers substantially higher forces compared with ISO 6020/2 cylinders — you get more output from the same bore diameter.

How do I select the most suitable DP hydraulic cylinder?

The online configurator lets you fully size and specify every feature of a DP cylinder, view the available options and immediately download 2D and 3D CAD models for direct integration into your projects.

How do DP cylinders cope with side loads?

The DP series has a double bronze guide system on the piston and a long rod guide bushing. This combination handles unwanted side loads that arise in demanding operations and could damage standard cylinders. The design is especially valuable in cases of misalignment or lateral stress.

How does end-of-stroke cushioning work on DP (ISO 6022) cylinders?

DP cylinders can be fitted with adjustable end-of-stroke cushioning with a quick-start system. The cushioning prevents mechanical shocks at the end of the stroke and adapts to the specific requirements and the loads being decelerated.

Can control systems be integrated into DP cylinders?

Yes. We offer versions with end-position sensors, CETOP plates for control valves, and a servo cylinder version (the TP series) with magnetostrictive linear position sensors.

When should I choose a DP hydraulic cylinder and how does it perform in harsh environments?

Choose a DP cylinder when the operating pressure reaches 250 bar, under significant side loads, or in particularly harsh environments. Special configurations with specific rod materials suit environments with abrasive dust and corrosive agents. Compatibility with phosphate esters and Viton® seals makes DP cylinders ideal for applications with aggressive media and elevated temperatures.

What are the lead times for DP cylinders, and are spare parts quickly available in urgent cases?

An extensive component stock enables extremely fast production — within 48 hours in urgent cases. Spare parts are held in stock with a fast service, and complete seal kits are immediately available for planned maintenance without long downtime.

At what pressure is every DP cylinder tested before dispatch?

All Conforti DP cylinders undergo a functional test at 375 bar in accordance with ISO 10100, ensuring reliability, safety and consistent performance.

DP / TP Hydraulic Cylinders

Q: What are the main applications of DP cylinders?

DP cylinders excel in rolling mills, forging presses and handling systems in steelworks, where conditions demand resistance to high temperatures, contaminants and intense mechanical stress. In presses, heavy machine tools and shearing systems, DP cylinders provide the stability needed to maintain accuracy under high loads.

ISO 6022 heavy-duty 250 bar for higher loads

Industrial double-acting hydraulic cylinders DP to ISO 6022 (DIN 24333) — a rugged tie-rod heavy-duty design for operating pressures of 250 bar (tested at 375 bar to ISO 10100), bore diameters Ø 50–200 mm, strokes up to 6000 mm and 8 mounting types. Double bronze guides handle side loads — ideal for presses, rolling mills, forming machines and plants under extreme stress.

The TP series adds a magnetostrictive absolute position sensor for precise servo control — continuous measurement of the whole rod travel up to a 4000 mm stroke.

TP servo cylinders → HD / HK Don’t need 250 bar? If your application stays below 210 bar and does not require ISO 6022, consider flange cylinders to ISO 6020/2 — they are more affordable and provide the same envelope for most industrial applications.

Heavy-duty, servo, or counterflange cylinder?

The DP series covers heavy-duty applications up to 250 bar and 6000 mm of stroke. The TP servo version adds a magnetostrictive absolute position sensor for precise control (up to 4000 mm). For applications up to 210 bar with no need for ISO 6022, the HD / HK series is more affordable.

Industrial applications

Where the cylinders are most often used

Rolling stands, forging presses and handling systems in steelworks, stamping presses, heavy machine tools and shearing systems — the heavy-duty DP series is designed for high temperatures, contaminants and intense mechanical stress.

The heavy-duty standard for 250 bar and side loads.

DP: Rolling mills, forging presses and handling in steelworks — resistance to high temperatures, contaminants and intense mechanical stress.
TP: Stamping and deep-drawing presses — position feedback controls both the blank holder and the tool with dimensional repeatability.
Side loads: The double bronze piston guides and the long rod guide bushing handle misalignment and lateral stress.
