Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250R is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 250mm 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 MI16X250R
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 250 mm stroke with a 1/8" air port. The riveted round-body construction pairs a corrosion-resistant barrel and rod, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston smoothly without the complexity of adjustable cushioning.
Because it conforms to ISO 6432 mounting dimensions, this Ø16 unit drops directly into standard mini-cylinder brackets and clevises. Plan for a safe working load of roughly 60 N at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin. The R back cover features an axial-in port orientation, simplifying rear plumbing in tight spaces. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG position switches without upgrading to an -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250R Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 100.5 N thrust to deflect light cardboard cartons at speed.
Lab Sample Ejector
Ejects plastic sample trays from a testing station, leveraging the stainless-steel body to resist chemical splashes and daily wipe-downs.
Textile Yarn Guide
Shifts a yarn guide carriage across a 250 mm path, where the fixed TPU bumpers quietly absorb the rapid directional changes.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250R the Right Cylinder?
When sizing this 250 mm stroke unit, verify the side-load limits: extending a Ø6 mm rod over a long distance increases the risk of rod bending, so guide the load externally if possible. If your task requires less push, the Ø12 bore offers 56.5 N at 0.5 MPa; stepping up to the Ø20 bore yields 157.0 N for heavier moves. The 1/8" port and M6x1.0 male rod thread are fixed by the bore size.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred—the fixed bumpers only soften the end of travel and act as neither a brake nor a position lock. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI16X250R FAQ
This Ø16 mm bore cylinder features a 1/8" air port and a Ø6 mm piston rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses standard ISO 6432 mounting dimensions and an R back cover with an axial-in port.
