Pneumatic Cylinders ISO15552
Pneumatic Cylinders
​
The design of pneumatic ISO15552 cylinders includes features that enhance their operational efficiency and durability. With a range of bore sizes and stroke lengths, these cylinders can be tailored to meet the specific requirements of various industrial tasks, from simple linear movements to complex automation processes. The use of high-quality materials and precision engineering in their construction results in robust performance even under demanding conditions.
​
Pneumatic Cylinders made to ISO 15552 available in various versions and with a wide range of accessories:
• Configuration with or without magnet
• Single-or double acting – single-or through-rod
• Wide choice of NBR, POLYURETHANE and FKM/FPM gaskets (for high temperatures), for LOW TEMPERATURE
• Piston rod scrapers for use in hostile environments available
• Special versions on request
• Fixing accessories, guide units and mechanical rod lock.
They are available in three versions, series STD, type A, series 3, which differ according to the shape of the barrel and, consequently, the type of sensors and accessories that can be mounted.
ISO 15552 CYLINDER
SERIES STD
ISO 15552 cylinders, featuring a smooth barrel with no longitudinal slots.
​
This means it is easier to clean the cylinder and there are fewer points where dirt can collect.
​
Specific brackets are required for mounting magnetic sensors.
​
​
​
​
​
​
ISO 15552 CYLINDER
SERIES 3
ISO 15552 pneumatic cylinders, featuring specially-shaped barrels designed to reduce weight to a minimum.
​
Two T-slots on the same side as the threaded fittings can take retractable sensors.
​
The other three sides of the barrel are smooth, with no slots, and hence easy to clean.

ISO 15552 LOW-FRICTION CYLINDER
The low-friction pneumatic cylinder is typically used as a dandy or tensioning cylinder since it is a single-acting cylinder without a return spring.
​
The configurations are shown below:
1) The best type is A as it involves less friction.
2) Type B should be used when the pneumatic cylinder is working under normal conditions outside the pneumatic cushioning area.
Cushioning is only for emergency use. It acts as a shock absorber in the case of malfunction.
3) Type C differs from type A due to the presence of a piston rod gasket that prevents dirt getting in when operating in dirty environments.
4) Type D differs from type B due to the presence of a piston rod gasket that prevents dirt getting in when operating in dirty environments.
5) Type E should be used when the pressurized chamber is the front one.
NB. THE CYLINDER IS ALWAYS SINGLE-ACTING WITHOUT A RETURN SPRING.
​
​
​
ISO 15552 ULTRA-LOW
FRICTIONS CYLINDER
A typical ultra-low friction pneumatic cylinder is generally used as an oscillating or tensioning pneumatic cylinder. It is single acting, in the sense that compressed air is normally fed into one of the two chambers only.
An external force acts on the other side. Metal Work’s ultra-low friction cylinder is designed as a double-acting one, which means the compressed air can be fed into the rear or either the front chamber.
They are built to comply with ISO 15552 and are available with or without a magnet.
​
Supplied with a series 3 barrel.
A through-rod version is not available.
These cylinders are always non-cushioned.
The gaskets are made of NBR.
A full range of accessories is available.
​
​
​
ISO 15552 TWO-FLAT CYLINDER
This version of pneumatic cylinder is used to keep the parts fixed to the piston rod at an angle and to apply torques within the specified limits.
​
The piston rod of the Two-Flat has two opposing longitudinal
surfaces; it is made of stainless steel.
​
The front pneumatic cylinder head includes a sintered bronze bush that matches the profile of the piston rod and prevents it from rotating on its own axis.
​
A special polyurethane gasket ensures pneumatic seal and prevents the accumulation of dirt.
This technical solution is more reliable and gives a better pneumatic seal than with square or hexagonal piston rods.
​
Supplied in series STD, with a smooth barrel, and type A or series 3, with a barrel with slots for retractable sensors.
​
They are available in several versions and with a wide range
of accessories:
​
• with or without magnet
• double acting, single piston rod
• double acting, through rod; one piston rod is Two-Flat,
the other cylindrical
• fixing accessories.

​
ISO 15552 CYLINDER
WITH END-OF-STROKE STOP
The pneumatic cylinders in this series are designed with a unit that mechanically locks the piston rod at the end of stroke.
​
When extended, the piston rod can be locked at the front head; when retracted, it is locked either at the rear head or in both positions.
​
With the cylinder pneumatically powered, the locking unit releases automatically, so no additional piloting is required.
​
The locking unit can be released manually by inserting a screw into a thread.
​
This pneumatic cylinder complies with ISO 15552, except for the length, which is greater than the standard.
