About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CA
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X15CA is a compact double-acting round-body mini cylinder built for short-stroke automation. Its stainless-steel barrel and piston rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown-prone environments. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because this specific SKU lacks the -S magnet suffix, it cannot host CMSG, DMSG, or EMSG reed switches for position sensing. It features a 1/8" port and an M8x1.25 male rod thread. For practical sizing, plan for a safe working load of about 94 N—roughly 60 percent of the 0.5 MPa rating—which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CA Is Used
Short-Stroke Clamping
Secures aluminium extrusions in a machining fixture using its 157 N push force within a tight 15 mm travel envelope.
Diverter Gate Pivot
Pairs with the CA clevis to swing a lightweight routing flap on a packaging line, enduring humid washdowns thanks to the stainless rod.
Carton Stopper Arm
Halts small cardboard cartons on a roller conveyor, safely handling the impact via fixed TPU bumper pads.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X15CA the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N. Choose this 15 mm stroke version when you need aggressive push force in an extremely tight footprint. The CA back cover equips the cylinder with a rear pivot clevis, ideal for articulating rod-end loads. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the TPU bumpers only decelerate the end of stroke and will not lock the load. For suspended masses, install an external pilot check valve. If your cycle demands position feedback, step up to the -S magnet variant.
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 MI20X15CA FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It uses a 1/8" air port and an M8x1.25 male rod thread.
The Ø20 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder clevises and brackets. However, because this specific SKU lacks the -S magnet, you cannot attach CMSG, DMSG, or EMSG magnetic switches for position sensing.
