About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CM
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X175CM is a double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and Ø8 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The 175 mm stroke operates at 30-800 mm/s, decelerated at the ends by fixed TPU bumper pads.
This Ø20 mm bore unit features a 1/8" port, an M8x1.25 male rod thread, and a CM round rear cover. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CM Is Used
Package Diverting
Pushes light cartons off a packaging line using the 157 N thrust, with the 175 mm stroke clearing guide rails easily.
Lab Sample Ejection
Ejects processed sample trays from a tester, where the stainless build resists chemical splashes and repeated wipe-downs.
Textile Loom Tensioning
Acts on a lever arm to maintain fabric tension, relying on the CM round rear cover for compact rear pivot mounting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175CM the Right Cylinder?
When sizing this 157 N (at 0.5 MPa) unit, consider the 131.9 N pull force and your actual load. If you need less power, the Ø16 bore provides 100.5 N of push; stepping up to the Ø25 yields 245.3 N. Because this is a 175 mm stroke, watch for side loads and rod-bending moments on the extended Ø8 mm rod. Note that this plain MI20X175CM SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors without switching to an -S variant. Furthermore, the fixed TPU bumpers only soften stroke-end impact; they will not hold a load if air pressure drops, so add an external rod lock or pilot check valve if you need vertical position holding.
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 MI20X175CM FAQ
This Ø20 mm bore cylinder has 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.
Yes, the Ø20 bore uses the ISO 6432 mounting interface, so it fits standard mini-cylinder clevises and foot brackets. However, this specific SKU has no internal magnet, so it cannot accept CMSG, DMSG or EMSG switches unless you specify the -S magnet option.
