Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 240mm 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 MI20X240SCA
Delivering 157 N of push force at 0.5 MPa, this AirTAC MI20X240SCA is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. The riveted construction shrinks the footprint while resisting mild corrosion, making it highly suitable for damp washdown environments. Its 240 mm stroke operates at speeds between 30-800 mm/s, and the 1/8" port feeds the Ø8 mm piston rod to cycle reliably. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the motion without the complexity of an adjustable cushion.
Because the 0.5 MPa push rating translates to roughly 16 kgf of raw force, a practical 2:1 safety margin means you can plan to lift about 8 kg vertically. For everyday horizontal actuation, budget for approximately 94 N of actual work. The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG switches for position sensing, while the ISO 6432 mounting interface ensures it drops straight into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SCA Is Used
Package Diverter Arm
Swings a lightweight routing gate on a packaging line, using the 157 N push force to redirect cartons at 30-800 mm/s without stalling.
Lab Sample Ejection
Stainless build withstands humid laboratory conditions, pushing tested specimens out of a washdown station over the 240 mm travel distance.
Pneumatic Press Pin
Drives a small locating pin into an assembly fixture, relying on the CA clevis to accommodate slight angular misalignment during the downstroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X240SCA the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, whereas the larger Ø25 provides 245.3 N. If your application demands high-speed cycling with heavier loads, the MIC variant offers a true adjustable air cushion instead of the fixed TPU bumpers found here. The included CA rear pivot cover is ideal for clevis mounting, accommodating articulation through an arc. For position feedback, the -S magnet pairs perfectly with CMSG, DMSG or EMSG sensors.
Keep in mind that a standard double-acting cylinder like this will drift if air pressure drops or the control valve is centred; the bumpers only soften the end-of-stroke impact and do not function as a braking lock. To suspend a load safely during an emergency stop, fit an external rod lock or a pilot-operated check valve. Additionally, the 240 mm stroke requires careful alignment to prevent rod bending and premature seal wear from side-loading forces.
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 MI20X240SCA FAQ
At 0.5 MPa this cylinder pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push increases to 219.8 N and the pull to 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It uses a 1/8" air port and an M8x1.25 male rod thread.
Yes, the -S suffix denotes an integrated piston magnet designed for CMSG, DMSG and EMSG reed or electronic switches. Regarding load holding, the cylinder will drift if air is lost; the fixed TPU bumper pads only decelerate the stroke end and do not lock the piston. Use an external pilot check valve to hold a suspended load.
