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.

General Data
| Type of construction | compact profile |
| Operation | single and double-acting |
| Materials | AL body and end-blocks – rolled stainless steel AISI 303 rod – AL piston rod PU seals or FKM seals for high temperatures (140°C) |
| Brackets | flange, feet, trunnion |
| Stroke min – max | Series 31R, 31M and 31F: Ø12÷25 = 1÷200mm, Ø32 ÷ 63 = 1÷300 mm, Ø80÷100 = 1÷400mm The min. stroke for the use of sensors is 10 mm. Single-acting = 5÷25 mm (see the table of standard strokes) |
| Operating temperature | 0°C ÷ 80°C (with dry air – 20°C) |
| Operating pressure | 1 ÷ 10 bar (double-acting); 2 ÷ 10 bar (single-acting) |
| Fluid | filtered air, without lubrication. If lubricated air is used, it is recommended to use oil ISOVG32. Once applied the lubrication should never be interrupted. |
| Speed | 10 ÷ 1000 mm/sec (without load) |
