Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 5mm 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 MI20X5CA
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles short 5 mm movements with precision. The riveted barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp environments. Because the stroke is so brief, plan for roughly 94 N of actual work to ensure smooth operation, which equates to lifting about 8 kg vertically under a 2:1 safety margin.
Built to ISO 6432 mounting dimensions, the unit drops directly into standard mini-cylinder brackets and clevises. It features a CA rear pivot cover for clevis mounting, a 1/8" air port, and an M8x1.25 male rod thread. Fixed TPU bumper pads absorb the end-of-stroke impact, and since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5CA Is Used
Short-Stroke Clamping
Ideal for locking small machined parts in CNC fixtures using the 5 mm stroke and 157 N of thrust.
Package Deflection
Quickly diverts light cartons on a packaging line where a brief 5 mm tap is sufficient to change flow.
Ejector Gates
Pushes small plastic molded components out of a mold cavity using the CA pivot clevis to handle side loads.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X5CA the Right Cylinder?
When sizing this 20 mm bore, stepping down to the 16 mm version drops the 0.5 MPa push force to 100.5 N, while moving up to the 25 mm bore increases it to 245.3 N. For this 5 mm stroke, side-load and rod-bending risks are virtually nonexistent, making it perfect for high-cycle clamping. Note that a standard cylinder drifts when air is lost or a valve is centered; the bumpers only decelerate the stroke end and do not act as a brake. To hold a load securely, add an external rod lock or a pilot-operated check valve. If sensing is required, select the -S magnet variant instead of this base model.
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 MI20X5CA FAQ
At 0.5 MPa it pushes with 157 N and pulls with 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 size is 1/8".
No, this specific SKU does not include a magnet. You must purchase the -S variant to use CMSG, DMSG, or EMSG switches. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
