Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 230mm 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 MI20X230SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 230 mm stroke with a Ø8 mm piston rod. The 1/8" port and M8x1.25 male thread provide robust pneumatic connections, while the riveted construction shrinks the footprint compared to bulkier alternatives. Fixed TPU bumper pads absorb end-of-stroke impacts, operating reliably across a 30-800 mm/s speed range.
The stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown settings. Because it features a built-in magnet (-S), it supports CMSG, DMSG, and EMSG position switches. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect cartons at 30-800 mm/s without corrosion risk in humid facilities.
Vertical Parts Lift
Raises lightweight plastic totes 230 mm; the 8 kg safe vertical lift capacity matches standard container weights in automated storage systems.
Pneumatic Clamping Arm
Extends a pivoting CA clevis-mounted arm to hold aluminum extrusions, relying on the 131.9 N pull force to retract the tooling quickly.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X230SCA the Right Cylinder?
When sizing this 230 mm stroke unit, consider the neighbouring bores: the Ø16 generates 100.5 N of push at 0.5 MPa, while the Ø25 steps up to 245.3 N. This model includes a CA rear pivot cover for clevis mounting and uses the ISO 6432 mounting interface, dropping easily into standard mini-cylinder brackets. At 230 mm, the extended Ø8 mm rod is susceptible to bending if subjected to lateral loads, so ensure pure axial alignment.
Note that venting or centering the valve causes the piston to drift, as the fixed bumpers only decelerate the stroke end rather than locking the load. To suspend a weight securely during air loss, integrate an external rod lock or pilot 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 MI20X230SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M8x1.25.
No, the fixed TPU bumper pads only decelerate the stroke end; they do not act as a brake, so the piston drifts if air is lost. Use an external rod lock or pilot check valve to hold a load. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG reed or electronic switches.
