Short-stroke cylinders Series RPA
Double-effect, magnetic
With hollow through rod and mounting stud
Bores: 20 and 30 mm
With hollow through rod and mounting stud
Bores: 20 and 30 mm
The Series RPA short stroke cylinders are double acting actuators with aluminium hollow through rod and mounting stud. Available in two sizes, Ø 20 and Ø 30 mm, with different strokes and dimensions of the mounting stud, these actuators are equipped with the non-rotating function of the rod.
The Series RPA are prepared for the mounting of magnetic sensors (Series CSD), in fact, on the external profile, along the cylinder tube, you can find sensor positioning slots.
Their compact and light design together with the adopted technical solutions make these cylinders suitable to be used, combined with suction pads, in End Of Arm Tooling (EOAT) systems, especially in the sector of plastic injection moulding.

Compact cylinders Series 31
Double and single-acting, double-acting non-rotating, magnetic
Ø 12, 16, 20, 25 mm
Ø 32, 40, 50, 63, 80, 100 mm UNITOP
The compact dimensions allow Series 31 single and double-acting magnetic cylinders to be installed within confined spaces.
These cylinders are suitable for use with feet, brackets.These cylinders are available in 10 different bore sizes from Ø12 to Ø100.
The guides are inserted in the external profile parallel to the sliding axis on three sides.
These guides are used to locate the switches that sense the piston position.
The construction design of these cylinders provides excellent axis stability.
They are available either with a male or female thread.
These cylinders can be supplied in W version for high temperatures (140°C).
This last version is not magnetic.
Cylinders ISO 15552 Series 63
Single and double-acting, magnetic, cushioned
Ø 32, 40, 50, 63, 80, 100, 125 mm
The Series 63 pneumatic cylinders have been developed to guarantee high performance and versatility.
Thanks to a new system of adjustable pneumatic cushioning, the cylinders can always guarantee the best regulation whilst significantly reducing noise caused by the impact of the piston on the end block.Besides the standard version, which can be used in many sectors, specific solutions have been developed for applications such as food processing, agriculture, in tensioning, dosing systems and dancer arms for winding applications.
There are also versions for demanding application environments, capable of withstanding extreme temperatures, corrosive atmospheres etc.
Positioning Feedback Cylinders ISO 15552 Series 6PF
Double-acting low friction, magnetic
Ø 50, 63, 80, 100, 125 mm
Series 6PF pneumatic actuators are equipped with a potentiometric linear position transducer integrated inside the rod.
This type of cylinder allows, along the entire stroke, a constant control of the rod position which is read processing the change of the transducer internal resistance.
The pistons have been equipped with a permanent magnet which enables the use of external end-stroke sensors.
The dynamic seals are specific for low friction.
Thanks to the electrical connection, realized by means of an M12 male electric round connector positioned on the rear head, these cylinders fulfil the standards of IP67 protection class.
Series 6PF cylinders comply with the ISO 15552 standards and can be assembled with the entire range of standard accessories.
They are available with bores from 50mm to 125mm with standard strokes from 50mm to 1000mm with intervals of 50mm.
The sturdy design, the flexible installation and the high performance make Series 6PF suitable for use in applications with tensioning cylinders, positioning cylinders and filling, cutting and measuring systems.
Series 32 compact cylinders, Tandem and Multi-position versions
Double-acting, magnetic
ø 25, 40, 63, 100 mm
Thanks to their great compactness Series 32 cylinders, Tandem and Multi-position, are suitable to be installed within confined spaces and can be used with the same mounting elements of other standard cylinders ISO15552.
The Tandem version enables to obtain up to 2 times the thrust force of a normal cylinder (standard traction force), while the Multi-position version can obtain up to three positions with one cylinder only.
Stainless steel cylinders Series 97
Single- and double-acting, cushioned, magnetic.
Ø 32, 40, 50, 63 mm
Series 97 stainless steel cylinders can be used in critical applications where a high level of corrosion resistance is required (for example: off-shore, naval, food industries).
These cylinders are normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.
In order to quieten the impact of the piston on the end block, these cylinders are also equipped with mechanical cushioning.
