About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 240 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch air port and an M8x1.25 male rod thread. An integrated piston magnet (-S) supports CMSG, DMSG, or EMSG reed and electronic switches for position sensing.
The stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. Its rolled, riveted construction keeps the body compact, while fixed TPU bumper pads absorb end-of-stroke impact. For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which translates to lifting an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SR Is Used
Package Diverter
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, where the stainless build withstands occasional washdowns.
Vertical Parts Lift
Raises 8 kg plastic bins between conveyor tiers within a 240 mm range, relying on the integrated magnet for precise position feedback.
Textile Guide Arm
Actuates a fabric guiding mechanism in a humid dye house, benefiting from the corrosion-resistant rod and fixed TPU bumper pads.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SR the Right Cylinder?
When sizing this 240 mm stroke model, the Ø16 bore provides 100.5 N push at 0.5 MPa, while the larger Ø25 offers 245.3 N if you need more power. The R back cover features an axial-in port orientation, and standard LB foot, FA flange, or TC trunnion brackets fit the ISO 6432 mounting dimensions. Because this is a 240 mm stroke, minimize side loading to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The TPU bumpers only decelerate the piston near the stroke end; they do not function as a locking brake. To suspend a load safely mid-stroke, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SR FAQ
This Ø20 mm bore cylinder features a 1/8 inch air port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the built-in -S magnet allows CMSG, DMSG, and EMSG switches for detection. For impact absorption, it uses fixed TPU bumper pads that decelerate the piston at the stroke ends; it does not have an adjustable air cushion.
