Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SR is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 15mm 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 MI16X15SR
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 15 mm strokes with precision. The Ø16 bore uses a 1/8 inch port and a Ø6 mm piston rod with an M6x1.0 male thread. Its riveted stainless construction resists mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
Because it carries an internal magnet, the -S suffix enables direct mounting of CMSG, DMSG or EMSG sensors for position detection. The rear R cover features an axial-in port orientation to streamline your tubing layout. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SR Is Used
Small Part Ejection
Uses the short 15 mm stroke to rapidly push lightweight plastic components out of an injection moulding die without overshooting.
Package Diverting
Deploys a brief 15 mm tapping arm to deflect small cardboard cartons on a packaging line, relying on the 100.5 N push force.
Lab Sample Clamping
Secures delicate glass vials during testing, where the stainless steel body withstands frequent chemical wipe-downs and washdown spray.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X15SR the Right Cylinder?
When sizing this actuator, the 15 mm stroke is ideal for very tight clamping or ejecting motions. If you need less force, the Ø12 bore provides 56.5 N push at 0.5 MPa, while stepping up to the Ø20 bore yields 157.0 N for heavier duty. This model conforms to ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises. You can also utilise LB foot, FA flange, SDB pivot or TC trunnion mounts.
Remember that the fixed TPU bumper pads only decelerate the piston near the stroke end; they do not act as a lock. If your application must hold a vertical load when air pressure drops or the valve centres, add an external rod lock or a pilot-operated check valve to prevent drift.
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 MI16X15SR 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. The air port size is 1/8 inch.
Yes, the -S magnet allows CMSG, DMSG and EMSG switches to detect the piston. The R back cover means the port enters axially straight out the back, which helps save space in tight machinery layouts.
