Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SR is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 300mm 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 MI16X300SR
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 300 mm stroke with a 1/8 inch air port. The riveted barrel and Ø6 mm piston rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because it carries the -S suffix, a built-in magnet enables CMSG, DMSG or EMSG switches for position sensing, while the R back cover provides an axial-in port orientation. For practical sizing, 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 MI16X300SR Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using 100.5 N of thrust, with the 300 mm travel reaching cleanly across the belt.
Lab Sample Ejection
Ejects plastic sample trays from a test station where the stainless barrel resists chemical splashes and mild washdown.
Parts Descender
Lowers lightweight electronic fixtures down a 300 mm path, relying on the DMSG sensor to confirm the bottom position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X300SR the Right Cylinder?
When sizing this 16 mm bore, dropping down to a 12 mm version drops the 0.5 MPa push force to 56.5 N, whereas stepping up to a 20 mm bore raises it to 157.0 N. The 300 mm stroke is well within the 500 mm maximum for this bore, but extending a Ø6 mm rod over that length increases side-load vulnerability, so guide the load to prevent rod bending. The R rear cover dictates a straight-in port line.
The integrated magnet pairs directly with CMSG, DMSG or EMSG sensors for end-of-stroke confirmation. Remember that venting the air or centering the valve lets the piston drift freely, as the TPU bumpers only soften the end stops rather than locking the payload; add a pilot check valve if you need to arrest movement.
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 MI16X300SR FAQ
This 16 mm bore cylinder uses a 1/8 inch 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, with a theoretical maximum of 20.5 kgf at 1.0 MPa.
The Ø16 bore uses standard ISO 6432 mounting dimensions for easy bracket matching, but this base MI variant only has fixed TPU bumper pads; you would need the MIC variant for adjustable air cushioning.
