Features and applications
The bronze rod guide bushing reduces friction during rod movement and, thanks to its properties, protects the surface from scratches, thus preserving the sealing capacity of the seals and preventing the occurrence of leaks.Adjustable hardened steel end-of-stroke cushioning ensures proper load deceleration at the end of the stroke, delivering long service life.
They can be equipped with proximity sensors to detect the position of the piston at both ends of the stroke.

Why choose ISO 6020/2 hydraulic cylinders with counterflanges rather than tie-rod cylinders?
Hydraulic cylinders with counterflanges provide superior stability for long-stroke applications by eliminating tie-rods and their elongation effects under demanding conditions. They enable higher operating pressures (210 vs 160 bar) whilst maintaining the same overall dimensions, in compliance with ISO 6020/2.
How can I select the hydraulic cylinder that best suits my requirements?
Our configurator guides you through selecting the most suitable hydraulic cylinder via a step-by-step procedure that validates your required configuration. You can download complete 2D and 3D models of the cylinders with all associated technical documentation. This tool enables immediate integration into your projects.
What control systems can be fitted to HD - HK hydraulic cylinders?
Versions with end-of-stroke sensors or linear position transducers are available, compatible with the main industrial automation systems. Thanks to integrated CETOP plates, control valves complying with ISO 4401 can be directly installed.
What are the operating and test pressures for HD - HK counterflange hydraulic cylinders?
The hydraulic cylinders operate at a nominal pressure of 210 bar and are tested at 315 bar to ISO 10100, ensuring maximum strength and safety during operation.
In urgent cases, what are the production times for a bespoke HD/HK hydraulic cylinder?
Our production organisation enables us to prepare your cylinder in extremely short lead times, down to 48 hours for urgent requirements.
What is the purpose of adjustable end-of-stroke cushioning?
HD - HK hydraulic cylinders can be equipped with end-of-stroke cushioning fitted with a quick restart system. The cushioning prevents mechanical shock at the end of the stroke and can be adjusted to suit specific requirements and loads to be decelerated.
Why do Conforti hydraulic cylinders have bronze rod guide bushings?
All our hydraulic cylinders feature bronze rod guide bushings. This material reduces friction during rod travel and thanks to its properties protects the rod surface from scratching, thereby preserving seal integrity and preventing leaks.
What bores are available?
HD counterflange hydraulic cylinders are available in all bores specified by ISO 6020/2 from 50 to 200 mm.
What seals are available?
A choice of high-performance seal configurations is available: high sealing, low friction, high temperature, and for special fluids. Metal wipers are also available, offering even better performance in removing debris from the rod when operating in dirty environments
