Airtac MI16-20 Stainless Steel Mini Cylinder MI20X310SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X310SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 310mm 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 MI20X310SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 310 mm stroke with a CA pivot clevis. 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 settings. Riveted construction keeps the body compact.
The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing. Plan for a real working load of about 94 N, which lets you lift roughly 8 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X310SCA Is Used
Package Diverter Arm
Swings a lightweight routing gate on a packaging line, using the CA pivot to articulate the arm and the 8 kg lift capacity to shift cardboard cartons.
Lab Sample Ejection
Pushes prepared specimens out of a testing jig over a 310 mm travel, where the stainless build resists chemical splashes and the magnet confirms ejection.
Bin Lid Actuation
Pivots heavy dust covers open on bulk storage bins in humid facilities, relying on the 157 N thrust to overcome the lid weight and friction.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X310SCA the Right Cylinder?
This Ø20 mm bore sits between the smaller Ø16 mm (100.5 N push @0.5 MPa) and the larger Ø25 mm (245.3 N push @0.5 MPa). Choose the 20 mm when the 16 mm lacks thrust or the 25 mm is physically too large. The 310 mm stroke is well within the 500 mm maximum, but at this length you must carefully control side loading to prevent rod bending. The CA rear pivot cover suits articulated mechanisms.
Because the -S magnet is present, you can fit CMSG, DMSG, or EMSG sensors directly. Remember that air pressure alone does not secure the load; if the valve centres or air drops, the piston drifts. The bumpers only decelerate the end of travel, so install a pilot check valve or external rod lock to hold a suspended weight.
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 MI20X310SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M8x1.25.
The CA back cover is a pivot clevis for articulated mounting. A standard cylinder drifts if air is lost and the fixed TPU bumpers only decelerate the stroke end, acting as neither a lock nor a brake. You must add a pilot check valve or external rod lock to hold a suspended load.
