Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 50mm 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 MI20X50CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The 20 mm bore and 50 mm stroke use a 1/8" port and an M8x1.25 male rod thread. Its CM round end back cover keeps the rear profile smooth for tight spaces. Built with a riveted stainless barrel and rod, it resists mild corrosion and washdown better than painted alternatives.
Because the 157 N rating is theoretical, plan for a real working load of about 94 N. This translates to lifting an 8 kg part vertically with a safe 2:1 margin. The fixed TPU bumper pads decelerate the piston at stroke end to reduce impact. Since this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CM Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using 157 N of force, where the stainless build survives occasional washdowns.
Small Parts Ejector
Ejects 8 kg moulded plastic components from a jig using the 50 mm stroke, relying on the fixed TPU bumpers to absorb the end impact.
Textile Loom Guide
Shifts a yarn guide precisely in humid textile facilities, leveraging the corrosion-resistant stainless steel barrel and rod.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50CM the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the 16 mm bore yields 100.5 N of push at 0.5 MPa, while the 25 mm bore provides 245.3 N. Choose this model if 157 N is sufficient for your task. The 50 mm stroke is well within the 500 mm maximum, keeping the rod highly resistant to bending. This cylinder conforms to ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises.
Remember that a plain double-acting cylinder drifts when air is removed or a valve is centred, as the TPU pads only soften the end of travel and act as neither a brake nor a lock. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Operating pressure spans 0.15-1.0 MPa across a 30-800 mm/s speed range.
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 MI20X50CM FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 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, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You must select the -S variant of the MI series to enable magnetic sensing. The unit uses ISO 6432 mounting dimensions and a CM round end cover.
