Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 175mm 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 MI20X175CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 175 mm stroke with a rear CA pivot clevis. The 20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The riveted construction keeps the body compact while fixed TPU bumper pads absorb impact at the stroke ends.
Because the 157 N rating is theoretical, plan for a safe working load of about 94 N to account for friction and pressure drops. For vertical moves, that translates to lifting roughly 8 kg safely with a 2:1 margin. This SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S version.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CA Is Used
Package Diverter Arm
Pivots a sorting gate on a packaging line using the CA clevis, relying on the 157 N thrust to push parcels smoothly at speed.
Vertical Parts Lift
Raises lightweight plastic totes 175 mm, safely lifting an 8 kg payload thanks to the stainless rod resisting mild workshop humidity.
Textile Loom Tensioner
Modulates yarn tension via a pivot bracket, where the compact riveted body and fixed TPU bumpers handle rapid cycling without harsh metal-on-metal impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CA the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N of push at 0.5 MPa, while the larger 25 mm bore provides 245.3 N. Choose the 20 mm when your load sits safely under its 94 N working capacity. The CA rear clevis suits pivot-mounting arrangements, and standard LB foot or FA flange brackets fit the ISO 6432 mounting interface. For the 175 mm stroke, ensure front-end alignment to prevent rod bending under side loads.
Remember that fixed TPU bumpers only soften end-of-stroke impacts; they do not function as an adjustable air cushion. If air pressure drops, the piston will drift, so fit an external pilot check valve or rod lock if your mechanism must hold a vertical load securely in place.
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 MI20X175CA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 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 specific SKU lacks an internal magnet and cannot support CMSG, DMSG or EMSG switches. You would need the -S magnet variant for sensing. It uses the ISO 6432 mounting interface and includes a CA rear pivot clevis.
