Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 125mm 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 MI20X125CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 125 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch 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. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk.
Because the Ø20 mm bore conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For actual moving work, plan for roughly 94 N of usable load at 0.5 MPa, which means it can comfortably lift about 8 kg vertically with a 2:1 safety margin. This specific SKU lacks the internal 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 MI20X125CA Is Used
Package Diverter Arm
Swings a sorting gate on a packaging line using the CA pivot mount, utilising the 157 N push force to redirect lightweight cartons at high speed.
Lab Sample Ejector
Pushes tested specimens out of a sterile chamber, where the stainless-steel construction prevents mild corrosion from repeated chemical wipe-downs.
Tote Tilting Mechanism
Employs the 125 mm stroke to pivot a small parts bin, safely lifting an 8 kg load capacity based on a 2:1 vertical lift margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X125CA the Right Cylinder?
When sizing this actuator, the neighbouring Ø16 bore offers 100.5 N of push at 0.5 MPa, while stepping up to the Ø25 bore yields 245.3 N. If your mechanism relies on gravity or loses air, remember that a standard MI will drift and cannot hold a load in place; the bumpers only decelerate the end of travel, so fit an external rod lock or pilot check valve if you need true position holding. The 125 mm stroke is well within the 500 mm maximum, but at this length you should guide the rod end to prevent side-loading and premature seal wear.
This unit arrives with a CA rear pivot cover, making it ideal for clevis mounting where the cylinder body needs to articulate during the stroke. Since this exact model has no -S suffix, it is unsuitable for magnetic position sensing.
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 MI20X125CA FAQ
This Ø20 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 force of 32 kgf at 1.0 MPa.
Yes for the clevis, as the CA back cover provides a pivot interface matching ISO 6432 dimensions. However, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG switches; you would need the -S variant for sensing.
