About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30CA
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 20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its CA rear pivot cover is built specifically for clevis mounting, accommodating angular rod movement during the short 30 mm stroke.
The stainless-steel barrel and rod resist mild corrosion, outlasting painted alternatives in damp or washdown environments. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. Plan for roughly 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 MI20X30CA Is Used
Gate Diverters
Actuates lightweight sorting flaps on packaging lines, using the CA clevis to accommodate the pivot arc during the 30 mm travel.
Product Reject Arms
Pushes misaligned cartons off a belt with 157 N of thrust at 0.5 MPa, relying on the stainless build for washdown durability.
Small Clamp Fixtures
Secures plastic housings during ultrasonic welding, safely applying around 94 N of clamping force without deforming the part.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X30CA the Right Cylinder?
When sizing this actuator, the 16 mm bore provides 100.5 N of push at 0.5 MPa, while the 25 mm bore offers 245.3 N if you need greater thrust. The fixed TPU bumper pads soften impact at the stroke ends but do not function as an adjustable air cushion. For high-speed cycling requiring variable cushioning, consider the MIC variant.
This model conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. Remember that a standard double-acting cylinder drifts if air pressure is lost or the valve is centred; the bumper only decelerates the end of travel. To hold a load securely, install an external rod lock or a pilot-operated check valve.
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 MI20X30CA FAQ
This 20 mm bore cylinder features a 1/8 inch port. 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 does not include a magnet. To use CMSG, DMSG or EMSG magnetic switches, you must select the -S variant. The unit does conform to ISO 6432 mounting dimensions for standard brackets.
