About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder is built for demanding 20 mm bore tasks. The Ø8 mm piston rod features an M8x1.25 male thread, and air connects via a 1/8" port. Riveted stainless construction resists mild corrosion and washdowns better than painted alternatives. The built-in magnet supports CMSG, DMSG, and EMSG switches for position sensing.
The CM round end back cover pairs with the 50 mm stroke to keep the envelope compact. Fixed TPU bumper pads absorb stroke-end impacts, operating reliably between -20 and +70 C at speeds of 30-800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCM Is Used
Package Diverter Gate
Pushes light cardboard cartons on a packaging line using its 8 kg vertical lift capacity and 50 mm stroke to actuate routing flaps.
Textile Loom Tensioner
Maintains consistent yarn tension in humid textile manufacturing thanks to the corrosion-resistant stainless steel barrel and rod.
Small Part Ejector
Ejects moulded plastic components from a machining zone, relying on the 157 N push force and fixed TPU bumpers to absorb the stroke impact.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCM the Right Cylinder?
When sizing this 20 mm bore actuator, compare it against its neighbours: a 16 mm bore yields 100.5 N of push at 0.5 MPa, while stepping up to a 25 mm bore provides 245.3 N. Choose this model when your application sits comfortably in the 94 N safe working range. Because the base MI uses fixed TPU bumpers rather than an adjustable air cushion, switch to the MIC variant if your cycle demands high-speed end-deceleration.
The -S magnet enables CMSG, DMSG, and EMSG electronic or reed sensors. Utilizing the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the bumpers only soften the stroke end. 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 MI20X50SCM FAQ
This 20 mm bore cylinder features a 1/8" air 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.
No, a standard double-acting MI cylinder will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the piston near the stroke end; they do not act as a brake. You must use an external rod lock or pilot check valve to hold a suspended load.
