Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 260mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles 260 mm of travel with a round, riveted body that shrugs off mild corrosion in damp or washdown environments. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread, while the built-in magnet allows direct mounting of CMSG, DMSG or EMSG switches for position sensing. Fixed TPU bumper pads absorb the end-of-stroke impact without the tuning required by an adjustable air cushion.
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 safe 2:1 margin. The CM round rear cover keeps the back end compact, and because the stroke sits well within the 500 mm standard limit, the Ø8 mm rod maintains good stability across the extension cycle.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCM Is Used
Package Diverter Arm
Pushes light cardboard cartons on a packaging line using 157 N of thrust, where the stainless body resists humidity from washdowns.
Textile Loom Tensioner
Extends 260 mm to position a yarn guide bar, relying on the built-in magnet to trigger DMSG sensors at the end of travel.
Bin Lid Actuation
Lifts an 8 kg hopper lid vertically using the 0.5 MPa air supply, with the CM round cover keeping the rear footprint tight against the frame.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCM the Right Cylinder?
When sizing this actuator, the Ø16 bore offers about 100 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245 N, making this 157 N unit the middle ground for moderate force tasks. Because the -S suffix includes a piston magnet, you can easily fit reed or electronic sensors without modifying the cylinder body. If your mechanism must stay put during an air loss or valve shift, remember that the TPU bumpers only decelerate the stroke end and will not act as a brake; add an external rod lock or pilot check valve to prevent drift. The 260 mm stroke is well within the 500 mm maximum, keeping side-load stress on the rod manageable, but ensure front mounting aligns true to avoid premature seal wear.
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 MI20X260SCM FAQ
This Ø20 mm bore cylinder features a 1/8" port and an M8x1.25 rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the Ø20 mm round body conforms to ISO 6432 mounting dimensions so it drops into standard mini-cylinder brackets and clevises. The -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches directly for position detection.
