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. This 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 provides significantly higher forces compared with ISO 6020/2 cylinders — you achieve more output from the same bore.

What are the main applications of DP cylinders?

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

How do I select the most suitable DP hydraulic cylinder?

The online configurator lets you fully dimension and specify all features of the DP cylinder, display the available options and instantly download 2D and 3D CAD models for direct integration into your projects.

How do DP cylinders perform under radial loads?

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

How does the end cushioning work on DP cylinders (ISO 6022)?

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

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 you choose a DP hydraulic cylinder and how does it perform in demanding environments?

Choose a DP cylinder when the operating pressure reaches 250 bar, under significant radial loads or in particularly demanding environments. Special configurations with specific rod materials are suitable for 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 up to 150 °C.

What are the delivery times of DP cylinders and are spare parts quickly available in urgent cases?

An extensive stock of components enables extremely fast production — up to 48 hours in urgent cases. Spare parts are in stock with quick service, and complete seal kits are immediately available for planned maintenance without long downtime.

At what pressure is each DP cylinder tested before dispatch?

Yes. 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 CylindersISO 6022 heavy-duty 250 bar for higher loads

Industrial double-acting hydraulic cylinders DP to ISO 6022 (DIN 24333) — a robust tie-rod heavy-duty construction for an operating pressure of 250 bar (375 bar test to ISO 10100), bore Ø 50–200 mm, stroke up to 6000 mm and 8 mounting types. Double bronze guiding handles radial loads — ideal for presses, rolling mills, forming machines and operations with extreme stress. The TP series adds a magnetostrictive absolute position sensor for precise servo control. Supplied by hydraulika.store, an authorised distributor of Conforti Oleodinamica — with an online configurator, free CAD models and delivery within 15–20 days (48 h for urgent orders).

Need continuous position control? The TP series is the servo version of DP with a magnetostrictive absolute position sensor (sensor max. stroke 4000 mm) — continuous measurement of the entire rod travel and precise servo control for test rigs, simulators and dynamic testing.

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

Three series · ISO 6022 and ISO 6020/2

When to choose the DP, TP or HD / HK series?

The DP series covers heavy-duty applications up to 250 bar and 6000 mm stroke. The TP servo version adds a magnetostrictive absolute position sensor for precise control (up to 4000 mm). For applications up to 210 bar without an ISO 6022 requirement, the more affordable HD / HK series (ISO 6020/2 with counter-flanges) is available.

Industrial applications

Where hydraulic cylinders are most often used

Rolling stands, forging presses and material handling systems in steelworks, stamping presses, heavy machine tools and shearing systems — the heavy-duty DP series (ISO 6022, 250 bar) is dimensioned for high temperatures, contaminants and intense mechanical stress, including significant radial loads and environments with abrasive dust and corrosive agents. The TP servo version with position measurement controls the blank holder and tool in stamping and deep-drawing presses with dimensional repeatability.
