Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 35mm 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 MI20X35CA
Generating 157 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder is built for compact automation. The riveted Ø20 mm barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp environments. Because it follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets without redesign.
The rear CA pivot cover allows angled articulation on moving arms, while the fixed TPU bumper pads quietly absorb end-of-stroke impacts. Lacking a -S suffix, this specific SKU has no internal magnet and cannot host CMSG or DMSG reed switches. 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.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35CA Is Used
Package Diverter Gate
Swings a lightweight sorting flap on a packaging line using the CA pivot, relying on the 157 N push force to overcome carton friction.
Textile Yarn Guide
Shifts a thread guide back and forth 35 mm; the stainless construction resists humid textile mill environments.
Bin Lid Actuator
Pivots a small hopper cover open and closed, where the fixed TPU pads adequately cushion the short 35 mm travel.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35CA the Right Cylinder?
When sizing this 35 mm stroke actuator, compare it against its neighbours: step down to an Ø16 bore for 100.5 N push, or up to a Ø25 bore for 245.3 N if the load demands more force. The 1/8" port and M8x1.25 male rod thread are fixed by the 20 mm bore. Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the bumpers only decelerate the stroke end rather than locking the rod. For suspended loads, add an external pilot check valve.
If your assembly requires position feedback, select the -S magnet variant to enable CMSG, DMSG or EMSG sensors. For high-speed cycles needing end-cushion tuning, consider the MIC series instead of relying on these fixed bumpers.
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 MI20X35CA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. The air port is 1/8".
No, this SKU lacks the internal magnet required for switches. You must choose the -S variant to use CMSG, DMSG or EMSG sensors. The rear CA cover provides a pivot clevis for mounting.
