Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SU 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 MI20X175SU
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 riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position detection.
For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which safely lifts about 8 kg vertically with a 2:1 margin. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. The rear U cover provides a 90-degree port orientation, simplifying hose routing in tight machinery.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SU Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 157 N thrust to push cardboard cartons onto an adjacent belt at speed.
Textile Loom Tensioner
Adjusts a yarn guide bar through the 175 mm stroke, relying on the stainless build to withstand humid manufacturing environments.
Bin Lid Lifter
Raises and lowers heavy hopper covers, safely lifting roughly 8 kg vertically while the 90-degree U cover keeps air lines compact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SU the Right Cylinder?
When sizing this 175 mm stroke model, compare it against neighbouring bores: the smaller Ø16 generates 100.5 N push, while the larger Ø25 provides 245.3 N at 0.5 MPa. If your process demands variable air cushioning for high-speed cycles, consider the MIC variant instead of this fixed-bumper design. The 1/8" port and M8x1.25 rod thread are fixed for this bore size.
Because the 175 mm stroke creates an extended lever arm, carefully manage side loads to avoid rod bending. A plain double-acting cylinder drifts when air is lost or the valve centres, as the TPU pads only decelerate the end of stroke without locking the load. To hold a suspended weight securely, integrate 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 MI20X175SU 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 force of 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG switches. However, it does not hold position on air loss; the fixed TPU bumper pads only decelerate the stroke end. Use an external rod lock or pilot check valve for load holding.
