Non rotating spring plungers Series NPM – NPR
These spring plungers are used in situations where significant height differences of the workpiece have to be compensated for.
Thread size M3, M5, G1/8, G1/4, plunger stroke length from 5 to 75 mm.
Thread size M3, M5, G1/8, G1/4, plunger stroke length from 5 to 75 mm.
The spring plungers are used in situations where significant height differences of the workpieces have to be compensated for.
The spring provides furthermore a gentle approach towards the workpiece without further complex controls in fully automated system, which is important when handling sensitive workpieces.
The spring provides furthermore a gentle approach towards the workpiece without further complex controls in fully automated system, which is important when handling sensitive workpieces.
Applications:
- Handling of parts with different heights (for example curved metal sheets)
- Handling of a very fragile parts (for example glass sheets), or parts with a delicate surface

Cylinders Series 40K
Double acting, cushioned, magnetic
Ø 160 - 200 - 250 - 320 mm
Series 40K cylinders comply with the ISO 15552 standard and can be assembled with the entire range of standard accessories.
A permanent magnet on the piston of these cylinders is able to send, through proximity switches mounted on the cylinder sliding axis, electrical signals to indicate its position.This series is normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.
END LOCK cylinders Series 63
Double-acting, magnetic, cushioned ø 32, 40, 50, 63, 80, 100, 125 mm
END LOCK pneumatic cylinders are fitted with automatic mechanical end stroke locks which guarantee safe and secure holding of the cylinder rod in both the fully retracted and fully extended positions.
The locks activate and release automatically, without the need for external signals or commands and cylinder END LOCK Series 63 comply with ISO 15552.
The automatic mechanical lock therefore makes the END LOCK cylinders Series 63 highly suitable for use in sectors and for applications where it is essential to lock the cylinder’s position, both to avoid sliding during long stops and in situations with an absence of air, for example in transportation, printing & paper and the woodworking industry.
In addition, their capability to withstand external forces, that are much higher than the force exerted by the piston, makes the END LOCK cylinder the ideal solution for applications such as lifters, positioners and presses where a greater degree of safety is required compared to the more traditional rod locks combined with blocking valves.
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.
Short-stroke cylinders Series RPA
Double-effect, magnetic
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.
