Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SR is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 175mm 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 MI20X175SR
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 175 mm stroke with ease. The Ø20 mm bore uses a 1/8" 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 environments. An integrated magnet (-S) supports CMSG, DMSG and EMSG position switches.
Because the ISO 6432 mounting interface is standard for this bore, it drops directly into common mini-cylinder brackets and clevises. The riveted round body stays compact, while fixed TPU bumper pads absorb stroke-end impact. For actual work, plan for roughly 94 N of usable load at 0.5 MPa, which equates to lifting about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SR Is Used
Bottle Line Diverter
Pushes lightweight guide rails on a beverage conveyor to sort plastic bottles, utilising the 157 N push force and stainless build to handle routine washdowns.
Carton Flap Folder
Extends 175 mm to fold small corrugated cardboard flaps on a packing machine, relying on the fixed TPU bumpers to prevent harsh impacts at high cycling speeds.
Lab Sample Ejector
Ejects tested fluid vials from a wet laboratory station, where the stainless rod shrugs off mild chemical exposure and the axial R rear port simplifies plumbing.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SR the Right Cylinder?
When sizing this unit, 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. This model includes the R back cover, meaning the rear port enters axially rather than radially. The built-in magnet allows seamless sensor integration, whereas a standard SKU without the S suffix cannot accept a switch. At 175 mm of travel, keep side-loads minimal to prevent rod bending and premature seal wear.
Remember that a plain cylinder drifts when air is removed or a valve is centred; the TPU bumpers only soften the end of travel and do not function as a locking brake. To suspend a load safely mid-stroke, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI20X175SR FAQ
This Ø20 mm bore cylinder features 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 of 32 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To maintain a vertical position, you must add an external rod lock or a pilot check valve.
