About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCM
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 inch port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod naturally shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG switches for position sensing.
Because the 157 N rating is theoretical, plan for a real working load of about 94 N at 0.5 MPa. This translates to safely lifting an 8 kg part vertically with a 2:1 margin. The CM round end cover keeps the rear profile smooth, while fixed TPU bumper pads absorb the impact at stroke extremes. Conforming to ISO 6432 mounting dimensions, it drops seamlessly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCM Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packaging line using its 157 N push force, while the stainless build withstands occasional washdown.
Textile Loom Tensioner
Extends 175 mm to position a yarn guide bar, relying on the CM round end cover and standard ISO 6432 brackets for straightforward installation.
Small Parts Ejector
Cycles rapidly to eject 8 kg tote bins from an assembly station, using the built-in magnet and a DMSG sensor to confirm full extension.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X175SCM the Right Cylinder?
When sizing this 175 mm stroke 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. If your application demands high-speed cycling with heavier loads, the MIC variant provides a true adjustable air cushion, whereas this base MI relies on fixed TPU bumpers. The -S magnet is essential here for mounting CMSG, DMSG, or EMSG sensors.
A 175 mm stroke exposes the Ø8 mm rod to greater side-load risks, so ensure your mounting guides the load cleanly to prevent rod bending. Remember that a plain cylinder drifts when air is lost or the valve is centred; the bumpers only decelerate the end of stroke and act as neither a lock nor a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MI20X175SCM FAQ
This Ø20 mm bore cylinder features a 1/8 inch 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 fixed TPU bumper pads only decelerate the piston near the stroke end and do not function as a brake. If air is lost or the valve is centred, the rod will drift. You must use an external rod lock or pilot check valve to hold a suspended load.
