Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 80mm 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 MI20X80CA
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X80CA is a double-acting round-body mini cylinder built for demanding pivot-mount applications. Its stainless-steel barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The 80 mm stroke operates at speeds of 30-800 mm/s, and the fixed TPU bumper pads absorb the impact at stroke end to protect your mechanism.
Because this specific SKU lacks the -S magnet option, it cannot host CMSG, DMSG or EMSG sensors. For sizing your payload, plan for a safe working load of roughly 94 N—about 60 percent of the 0.5 MPa rating—or expect it to lift an 8 kg mass vertically with a 2:1 safety margin. The 1/8" port supplies air efficiently, while the CA back cover provides an integral pivot clevis for articulated linkage tasks.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CA Is Used
Pivoting Component Ejector
Uses the CA clevis to swing an 8 kg stamped metal part out of a press bed, utilising the 157 N push force at 0.5 MPa to clear the die area quickly.
Packaging Lane Diverter
Actuates a sorting arm to push medium-weight cartons between parallel packaging lines, relying on the stainless construction to endure humid factory washdowns.
Pallet Guide Arm
Deploys an 80 mm stroke to tension a guide rail against incoming pallets, absorbing the impact through fixed TPU bumper pads without needing a cushion adjustment.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CA the Right Cylinder?
When sizing this 20 mm bore, stepping down to the Ø16 MI yields 100.5 N of push at 0.5 MPa, whereas moving up to the Ø25 MI provides 245.3 N. This makes the MI20X80CA the sweet spot for medium-force articulating mechanisms. Its CA rear clevis is ideal for pivoting loads, complemented by standard LB foot, FA flange or TC trunnion front options. Remember that the fixed TPU bumpers only decelerate the stroke end; they do not function as a lock. If your pivot arm must remain suspended during a pressure drop, add an external rod lock or pilot check valve.
The 80 mm stroke is well within the 500 mm maximum for this bore, keeping the rod bending risk low. Because this configuration omits the -S magnet, position sensing is impossible on this unit; if your sequence requires end-of-stroke confirmation, switch to the MI20X80CA-S variant to enable CMSG, DMSG or EMSG switches.
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 MI20X80CA FAQ
The 20 mm bore generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. Air is supplied via a 1/8 inch port, and the male rod thread is M8x1.25.
No, this specific SKU does not include the -S magnet, so CMSG, DMSG or EMSG switches cannot be mounted. You would need the MI20X80CA-S variant for sensing. Additionally, the stainless build meets ISO 6432 mounting dimensions for easy bracket interchange, and the fixed TPU bumpers simply decelerate the stroke end rather than acting as an adjustable air cushion.
