About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCMTC
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 Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the CM round end and TC trunnion mounting offer versatile installation. Fixed TPU bumper pads decelerate the stroke ends. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it lifts roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCMTC Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 8 kg vertical lift capacity to redirect small cardboard cartons efficiently.
Small Part Ejector
Pushes machined plastic components out of a fixture, utilizing the 94 N safe working load to clear parts without stressing the tooling.
Pneumatic Sorting Arm
Equipped with a TC trunnion and CM round end to swing a lightweight sorting arm, accurately placing items into distribution chutes.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SCMTC the Right Cylinder?
When sizing this bore, stepping down to the Ø16 MI yields 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 MI provides 245.3 N. This 20 mm option sits perfectly in the middle for moderate force needs. Because the base MI relies on fixed TPU bumpers rather than an adjustable cushion, consider the MIC variant if your application demands variable end-of-stroke deceleration at high speeds.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred, as the bumpers only soften impact and do not function as a brake. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve. The TC trunnion pairs with the CM rear cover to manage pivoting loads on this 50 mm stroke.
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 MI20X50SCMTC FAQ
This Ø20 mm bore cylinder features 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 force of 32 kgf at 1.0 MPa.
The fixed TPU bumpers only decelerate the stroke end; they do not lock the rod, so the piston will drift if air is lost. For load holding, use an external rod lock or pilot check valve. The included -S magnet allows CMSG, DMSG and EMSG switches to detect position.
