About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X125SR
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The 16 mm bore uses an M5×0.8 port and a 6 mm piston rod, while the 125 mm stroke falls well within the 500 mm standard limit. Its riveted round-body construction shrinks the footprint compared to bulkier alternatives, and the stainless barrel shrugs off mild corrosion in damp environments.
The built-in magnet supports CMSG, DMSG, or EMSG switches for position sensing. Because the rear cover uses an R axial-in port orientation, plumbing stays neatly in line with the body, and the ISO 6432 mounting dimensions let you drop it straight into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X125SR Is Used
Small Part Ejection
Uses the 100.5 N push stroke to knock lightweight plastic molded parts out of a machining fixture on an assembly line.
Package Diverting
Extends 125 mm to push small cardboard cartons from a main conveyor belt onto a secondary sorting lane.
Clamp Actuation
Secures thin aluminum brackets during a light drilling operation, utilizing the 86.4 N pull force for reliable holding.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X125SR the Right Cylinder?
If 100.5 N is too much force, the smaller Ø12 bore offers 56.5 N; if you need more muscle, stepping up to the Ø20 bore provides 157.0 N at the same 0.5 MPa. This SKU includes the -S magnet for position feedback, but remember that a standard cylinder drifts when air is removed or a valve is centered, so add an external rod lock or pilot check valve if you need to hold a vertical load safely. With a 125 mm stroke, keep side loads minimized to prevent rod bending.
The fixed TPU bumper pads absorb end-of-stroke impact to protect the mechanism, though they are not an adjustable air cushion. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions to suit your frame.
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 MI16X125SR FAQ
This 16 mm bore cylinder features an M5×0.8 port and generates 100.5 N push / 86.4 N pull at 0.5 MPa, 140.7 N push / 120.9 N pull at 0.7 MPa, and a theoretical maximum of 20.5 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the round body for precise position detection.
