About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SR
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with ease. The Ø16 mm bore uses a 1/8" port and an M6x1.0 male rod thread, while the built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG switches for position sensing. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments.
The riveted round body incorporates fixed TPU bumper pads that decelerate the piston at the stroke ends, and it conforms to ISO 6432 mounting dimensions for straightforward bracket integration. For actual work, plan for about 60 N of usable load at 0.5 MPa. This equates to lifting roughly 5.1 kg vertically with a 2:1 safety margin, ensuring you can match the cylinder to real part weights without overloading it.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SR Is Used
Package Sorting Diverter
Pushes light cardboard cartons on a packaging line using its 100.5 N thrust and 250 mm travel range.
Lab Sample Ejection
Ejects plastic sample trays from a testing fixture, leveraging the stainless build for cleanroom compatibility.
Bin Gate Actuation
Opens and closes small gravity-fed dispenser gates where the 86.4 N pull force retracts the rod cleanly.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250SR the Right Cylinder?
If 60 N of working force is insufficient, step up to the Ø20 bore (157.0 N push at 0.5 MPa); if your payload is lighter, the Ø12 bore offers 56.5 N. This 250 mm stroke is well within the 500 mm maximum for the Ø16 bore, though at this length you should ensure front mounting guides to prevent rod bending under side loads. The R back cover provides an axial-in port orientation to simplify plumbing. Because a standard cylinder vents and drifts when air is lost or the valve is centred, add an external rod lock or pilot check valve if the load must be held in place.
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 MI16X250SR FAQ
This Ø16 mm bore cylinder features a 1/8" port and an M6x1.0 male rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The cylinder uses fixed TPU bumper pads to decelerate the stroke end; it does not have an adjustable air cushion (for that, see the MIC variant).
