About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X155CA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø16 mm bore features a 1/8" port and a 155 mm stroke, while the integrated CA rear pivot cover allows direct clevis mounting for articulating mechanisms. Its stainless barrel and rod naturally shrug off mild corrosion, outperforming painted alternatives in damp or washdown-prone environments.
Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets without redesign. Fixed TPU bumper pads absorb end-of-stroke impacts to protect the mechanism. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; add the -S variant if your control system requires electronic sensing. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X155CA Is Used
Component Ejection
Pushes small stamped metal parts out of a press die using 100.5 N of force, relying on the stainless rod to resist coolant mist.
Pivoting Diverter Arm
Actuates a sorting gate along a packaging line, utilising the CA rear clevis to maintain smooth angular movement during transit.
Lab Sample Routing
Indexes test tube racks inside a humid analytical machine, where the washdown-resistant stainless barrel prevents corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X155CA the Right Cylinder?
When sizing this 16 mm bore, verify your actual load against the 60 N safe working threshold. If your task requires less force, the smaller Ø12 bore provides 56.5 N of push at 0.5 MPa, whereas stepping up to the Ø20 bore yields 157.0 N for heavier resistance. The 155 mm stroke is well within the 500 mm maximum, but at this extension you must carefully manage side loading to avoid bending the Ø6 mm piston rod. The CA pivot back cover is ideal for accommodating slight misalignment on swinging loads.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke ends; they do not function as a brake. If the air supply drops or the directional valve centres, the rod will drift and drop the load. To maintain vertical position safely, install an external pilot-operated check valve or a dedicated rod lock. Furthermore, since this configuration omits the magnet, you cannot mount reed or solid-state sensors directly to the body.
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 MI16X155CA FAQ
This 16 mm bore double-acting cylinder uses a 1/8" port and generates 100.5 N push and 86.4 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N and the pull to 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S magnet variant if your application requires electronic end-of-stroke detection.
