About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted construction uses a stainless barrel and rod to resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Its fixed TPU bumper pads decelerate the stroke end to reduce impact, operating at speeds of 30-800 mm/s.
Featuring a 20 mm stroke and a CA pivot clevis back cover, it integrates smoothly into articulated mechanisms. The 1/8" port supplies air efficiently, while the ISO 6432 mounting interface drops directly into standard mini-cylinder brackets. Plan for about 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 MI20X20CA Is Used
Short-Stroke Clamping
Ideal for holding small aluminum extrusions in a machining fixture, utilizing the 157 N push force to secure the part without deforming it.
Package Diverter Arm
The CA pivot clevis pairs perfectly with a short 20 mm stroke to flick lightweight cardboard cartons onto an adjacent packaging line.
Lab Sample Ejection
Stainless construction withstands daily wipe-downs in pharmaceutical labs, while the compact 20 mm movement precisely kicks test tubes out of a carousel.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X20CA the Right Cylinder?
When sizing this 20 mm bore, stepping down to the Ø16 class drops the 0.5 MPa push force to 100.5 N, while moving up to the Ø25 bore raises it to 245.3 N. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; you must select an -S variant if your application requires electronic sensing. You can mount it using LB foot, FA flange, SDB pivot or TC trunnion hardware alongside the built-in CA clevis.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the TPU bumpers only soften the end of travel rather than locking the rod. To suspend a load safely mid-stroke, incorporate an external pilot-operated check valve or a dedicated rod lock. The short 20 mm stroke also keeps rod bending stress minimal even under slight side-loading.
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 MI20X20CA FAQ
This 20 mm bore cylinder uses 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 force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must purchase an MI20X20CA-S variant to use CMSG, DMSG or EMSG reed switches. This base model relies solely on its fixed TPU bumper pads to decelerate the piston at the stroke ends.
