Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 260mm 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 MI20X260SCA
Delivering 157 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder handles robust actuation tasks. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. With a 260 mm stroke, it uses standard ISO 6432 mounting dimensions to drop directly into existing mini-cylinder brackets.
Fitted with a CA pivot clevis at the rear, the unit swings freely to accommodate lateral shaft movement. The built-in -S magnet supports CMSG, DMSG, and EMSG switches for position sensing. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb end-of-stroke impacts across the 30-800 mm/s speed range.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCA Is Used
Package Diverter Arm
Swings on the CA clevis to push 5 kg cartons off a sorting belt, relying on the 157 N push force to overcome friction.
Textile Loom Tensioner
Uses the 260 mm stroke to maintain fabric tension in humid dye-house conditions where the stainless barrel prevents rust.
Pallet Label Applicator
Extends to press labels onto pallets, triggering a DMSG sensor via the -S magnet to confirm the 8 kg press force.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X260SCA the Right Cylinder?
When sizing this 20 mm bore, the smaller MI16 yields 100.5 N of push at 0.5 MPa, while the larger MI25 provides 245.3 N, letting you step up or down if the 157 N output misses the target. The CA rear clevis is ideal for pivoting loads, but remember that venting the air causes the piston to drift; fit an external rod lock or pilot check valve if the mechanism must hold position during an air loss. Because the 260 mm stroke is relatively long for a mini cylinder, support the rod end or guide the load to prevent side-loading and premature shaft bending.
This SKU includes the -S magnet for electronic or reed sensors, and uses a 1/8 inch port for air supply. The fixed TPU bumpers decelerate the stroke end but do not act as a lock.
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 MI20X260SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8 inch.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve to hold loads securely.
