About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X185SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 185 mm stroke with ease. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments, while the built-in piston magnet supports CMSG, DMSG and EMSG sensors for position detection.
Featuring a 1/8" port and an M6x1.0 male rod thread, the unit conforms to ISO 6432 mounting dimensions for straightforward bracket integration. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X185SU Is Used
Package Diverting
Pushes small cartons off a packaging line using 100.5 N of thrust, with the 185 mm stroke reaching cleanly across the conveyor belt.
Lab Sample Ejection
Ejects processed sample trays from testing equipment, where the stainless build withstands frequent wipe-downs and mild chemical exposure.
Small Part Sorting
Actuates a diverter gate to route plastic moulded components into collection bins using position feedback from the integrated magnet.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X185SU the Right Cylinder?
When sizing this 16 mm bore, stepping down to the Ø12 yields 56.5 N push, whereas moving up to the Ø20 provides 157.0 N at 0.5 MPa. This model includes the U back cover for 90-degree mounting and the -S magnet for switch readiness. Remember that a standard cylinder drifts if air pressure drops; the fixed TPU bumper pads only soften the stroke end, so add an external rod lock or pilot check valve if you need to hold a load securely.
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 MI16X185SU FAQ
At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa, and the air port size is 1/8".
No, it uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. It does conform to ISO 6432 mounting dimensions for standard mini-cylinder brackets, and the -S suffix means it includes a magnet for CMSG, DMSG or EMSG sensors.
