What does it mean that the hydraulic cylinders comply with ISO 6020/2?

ISO 6020/2 defines the dimensions, mountings and design criteria for tie-rod hydraulic cylinders rated at 160 bar. This guarantees interchangeability and compliance with international standards.

What is the operating pressure of tie-rod hydraulic cylinders?

Tie-rod hydraulic cylinders to ISO 6020/2 operate at a nominal pressure of 160 bar and are tested at 240 bar in accordance with ISO 10100, ensuring maximum strength and safety in operation.

What are the lead times for a custom ISO 6020/2 cylinder in urgent cases?

The production organisation makes it possible to prepare a custom ISO 6020/2 hydraulic cylinder in a very short time — in emergencies within 48 hours.

What is the adjustable end-of-stroke cushioning for?

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

In which applications are ISO 6020/2 tie-rod cylinders used?

They are used in industrial plants and machines requiring precise, powerful linear movements combined with high reliability — for example sheet-metal processing lines, lifting and handling equipment, automation lines and special-purpose machinery.

Can tie-rod cylinders be equipped with magnetic sensors?

Yes. MD cylinders are designed for use with REED or special magnetic sensors that allow precise monitoring of the piston position and full control of the working cycles.

Which seals are available?

Several high-performance seal configurations are available: high seal (S), low friction (L), high temperature (H – Viton) and special media (G – HFC). Metal scraper rings are also available for operation in contaminated environments.

Is every hydraulic cylinder tested before delivery?

Yes. All Conforti tie-rod cylinders undergo a functional test at 240 bar in accordance with ISO 10100, guaranteeing reliability, safety and consistent performance.

Why do Conforti hydraulic cylinders have a bronze rod guide bushing?

All hydraulic cylinders have a bronze rod guide bushing. This material reduces friction during rod movement and protects the surface from scoring, preserving the sealing capability of the seals and preventing oil leakage.

Are Conforti CD / DK cylinders interchangeable with Parker or Bosch Rexroth?

Yes. CD / DK cylinders are manufactured to ISO 6020/2 (DIN 24554), which defines a uniform envelope and mounting dimensions. This makes them directly interchangeable with Parker Hannifin, Bosch Rexroth, Festo and other cylinders without modifying the machine.

Is hydraulika.store an authorised Conforti distributor and is the manufacturer certified?

Yes. hydraulika.store is an authorised distributor of Conforti Oleodinamica — genuine cylinders with the full manufacturer's warranty, technical support and invoicing in EUR. The manufacturer Conforti has been ISO 9001 certified since 2008 and every cylinder undergoes an individual test to ISO 10100 before dispatch.

Need piston-position sensing? The MD series has a magnetic piston and SH / SR sensors clamped onto the tie-rods — sliding anywhere along the stroke (intermediate and end positions), they signal the piston position to the PLC. Same envelope as CD / DK, just with a magnetic piston. More about MD cylinders with sensors →

Need a stroke over 2000 mm? The HD / HK series uses the same ISO 6020/2 standard but with counter-flanges — better suited to long strokes than tie-rod CD / DK thanks to higher stiffness and better buckling resistance. Operating pressure 210 bar, stroke up to 4000 mm. View HD / HK cylinders for long strokes →

Industrial applications

Examples of hydraulic cylinder use in industry

Sheet-metal processing lines, lifting and handling equipment, automation lines and special-purpose machines — CD / DK tie-rod cylinders to ISO 6020/2 are the standard for everyday industrial motion up to 160 bar. The MD series with magnetic sensors additionally serves workpiece clamping and locking systems on CNC machines (position confirmation before machining) and the control of complex motion sequences. Thanks to standardised envelope dimensions, CD / DK / MD are a direct replacement for Parker, Bosch Rexroth and Festo cylinders.
