Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 375mm 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 MI20X375CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 375 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Built-in fixed TPU bumper pads absorb stroke-end impact, while the CA rear pivot cover allows direct clevis mounting.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it lifts roughly 8 kg vertically with a 2:1 safety margin. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. The 375 mm stroke is well within the 500 mm standard maximum, and the body conforms to ISO 6432 mounting dimensions for easy bracket integration.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375CA Is Used
Package Diverter Gate
Pivots a sorting flap on a packaging line using the CA clevis, applying 157 N of push to redirect cartons at high speed.
Vertical Parts Lift
Raises lightweight plastic totes 375 mm; safely lifts an 8 kg assembly with a 2:1 margin under 0.5 MPa supply.
Textile Loom Tensioner
Acts as a double-acting tensioning arm in a humid textile facility, leveraging the stainless steel rod to resist mild corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375CA the Right Cylinder?
When sizing this unit, the neighbouring Ø16 bore offers 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N, so the Ø20 sits perfectly in the mid-range. The CA back cover provides a rear pivot point for clevis mounting, complementing standard LB foot, FA flange and TC trunnion options. At 375 mm, the stroke is long for a mini cylinder, so ensure your front mounting guides the load to prevent rod bending and side-load wear.
Remember that a plain double-acting cylinder drifts when air is removed or the valve is centred, as the TPU bumpers only decelerate the end of travel and act neither as a lock nor a brake. To suspend a load safely, fit an external rod lock or a pilot-operated check valve. If your application requires position sensing, you must select the -S magnet variant to enable switch mounting.
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 MI20X375CA FAQ
This Ø20 mm bore cylinder features a 1/8 inch air port and an M8x1.25 male rod thread. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for position sensing. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and its ISO 6432 mounting dimensions fit standard mini-cylinder brackets.
