Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCM is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 20mm 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 MI16X20SCM
Delivering 100.5 N of push force at 0.5 MPa, the AirTAC MI16X20SCM is a double-acting round-body mini cylinder built for compact automation. The stainless-steel barrel and Ø6 mm rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. Its 20 mm stroke and CM round rear cover keep the footprint tight, while the 1/8" port ensures efficient air flow for rapid cycling.
Because it conforms to the ISO 6432 mounting interface, this 16 mm bore unit drops directly into standard mini-cylinder brackets and clevises. The riveted body houses fixed TPU bumper pads that absorb stroke-end impact without the tuning hassle of an adjustable cushion. For practical sizing, plan for a safe working load of about 60 N, which means it can comfortably lift a 5.1 kg part vertically with a 2:1 safety margin. The built-in piston magnet (-S) is ready for CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCM Is Used
Small Part Ejection
Uses the 100.5 N push stroke to knock lightweight plastic mouldings from a conveyor into a sorting bin.
Clamp Actuation
Secures aluminium brackets in a milling fixture, relying on the 86.4 N pull force to release the part.
Flap Folding
Folds cardboard carton flaps in a humid packaging line where the stainless barrel resists moisture.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X20SCM the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, while stepping up to a 20 mm bore provides 157.0 N. The MI16X20SCM hits a useful middle ground for 60 N workloads. If your mechanism must hold a vertical load when air is removed or the valve is centred, note that this plain cylinder will drift downward—the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. You will need an external rod lock or a pilot-operated check valve to secure the payload.
The CM round end back cover offers specific rear-porting and mounting geometry for tight spaces. Thanks to the included -S magnet, you can mount CMSG, DMSG or EMSG sensors directly for end-of-stroke confirmation. At a short 20 mm stroke, side-load stress on the Ø6 mm rod is minimal, but always ensure the load travels on a smooth linear guide to prevent rod binding.
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 MI16X20SCM FAQ
This 16 mm bore cylinder features a 1/8" air port and an M6x1.0 male rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed and electronic switches. The unit uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
