Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 90mm 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 MI20X90CA
Generating 157 N of push force at 0.5 MPa, the AirTAC MI20X90CA is a double-acting round-body mini cylinder built for demanding 90 mm stroke tasks. The stainless-steel barrel and piston rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Its riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke extremes. This CA back-cover version features a rear pivot clevis, and because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.
For practical sizing, plan for a safe working load of about 94 N, which is roughly 60% of the 0.5 MPa push rating. Alternatively, it can lift an 8 kg part vertically when applying a 2:1 safety margin. The 1/8" port supplies air efficiently, and the body conforms to ISO 6432 mounting dimensions, allowing it to drop directly into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90CA Is Used
Diverter Gate Actuation
Drives light pivot gates on packaging conveyors, using the CA clevis to swing 90 mm and route small cartons at 157 N push force.
Parts Ejection
Pushes completed plastic mouldings out of a cell, safely moving parts weighing up to 8 kg vertically with a 2:1 safety margin.
Lab Sample Handling
Moves sample racks in damp laboratory environments where the stainless-steel barrel prevents mild corrosion from repeated washdowns.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X90CA the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the 16 mm bore yields 100.5 N of push at 0.5 MPa, while the 25 mm bore offers 245.3 N. Choose this 90 mm stroke model when your application requires moderate force within a compact footprint. If your mechanism needs to maintain vertical position during an air loss or valve centre state, remember that this cylinder will drift; the TPU bumpers only decelerate the end of stroke and do not act as a brake. An external rod lock or pilot-operated check valve is required to hold a suspended load safely.
The integrated CA rear pivot clevis suits angular movement requirements. Should you need adjustable end-deceleration for high-speed cycles instead of the standard fixed bumpers, consider the MIC variable-cushion variant. For position feedback, you must select the -S magnet version to mount CMSG, DMSG or EMSG sensors.
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 MI20X90CA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You must order the -S variant for position sensing. It uses fixed TPU bumper pads for deceleration and relies on its CA pivot clevis for mounting.
