Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CATC
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CATC 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 MI20X80CATC
Delivering 157 N of push force at 0.5 MPa, this AirTAC MI20X80CATC is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. The riveted construction shrinks the footprint while resisting mild corrosion in damp or washdown environments. Because it lacks the -S suffix, this specific SKU cannot host CMSG, DMSG or EMSG magnetic sensors. It features a CA rear pivot cover and a TC trunnion mount, while the 1/8" port drives the 30-800 mm/s speed range.
Plan for roughly 94 N of actual work at 0.5 MPa, which safely lifts an 8 kg vertical load with a 2:1 margin. Fixed TPU bumper pads absorb the impact at the stroke ends, decelerating the piston without offering adjustable cushioning. The Ø20 bore uses standard ISO 6432 mounting dimensions, so it drops directly into common mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CATC Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using the 157 N thrust, with the TC trunnion absorbing side pivot forces.
Textile Loom Tensioner
Maintains yarn tension in a humid textile facility, leveraging the stainless steel rod to resist mild corrosion and washdown.
Bin Lid Actuator
Opens and closes lightweight access hatches on sorting bins, safely lifting components under 8 kg via the 80 mm stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X80CATC the Right Cylinder?
If you need less force, the Ø16 bore provides 100.5 N of push at 0.5 MPa; if you need more, the Ø25 bore steps up to 245.3 N. The 80 mm stroke is well within the 500 mm maximum, keeping rod bending stress low. The included TC trunnion pairs with the CA back cover to handle pivoting loads. Remember that venting the air supply causes the piston to drift, as the TPU bumpers only soften stroke-end impact rather than locking the rod. Use a pilot-operated check valve if you must hold a load mid-stroke.
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 MI20X80CATC FAQ
This Ø20 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 of 32 kgf at 1.0 MPa.
No, this SKU lacks the -S suffix, so it has no internal magnet and cannot accept CMSG, DMSG or EMSG switches. You must order an MI20X80CATCS variant for position sensing. The fixed TPU bumpers only decelerate the stroke end and do not act as an adjustable air cushion.
