Airtac MI16-20 Stainless Steel Mini Cylinder MI20X330SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X330SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 330mm 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 MI20X330SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 330 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp washdown environments.
Because it carries the -S suffix, an internal magnet allows CMSG, DMSG or EMSG switches to track piston position. The built-in CA pivot clevis simplifies rear mounting, while fixed TPU bumper pads absorb end-of-stroke impacts. For real-world tasks, plan for a safe working load of roughly 94 N, which means it can vertically lift about 8 kg with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X330SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 330 mm stroke to shift parcels between belts while the stainless body shrugs off humid ambient conditions.
Vertical Parts Descender
Lowers lightweight 8 kg fixtures down a 330 mm drop, relying on the 157 N push force at 0.5 MPa to overcome friction and gravity reliably.
Textile Loom Tensioner
Pivots a yarn tensioning arm via the CA clevis, maintaining thread tension where the washdown-resistant stainless rod prevents fiber snagging.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X330SCA the Right Cylinder?
This Ø20 mm bore sits between the smaller MI16 (100.5 N push @0.5 MPa) and the larger MI25 (245.3 N push @0.5 MPa), giving you a clear upgrade path if your force requirements shift. The 330 mm stroke is well within the 500 mm maximum standard stroke for this bore, though at extended lengths you should verify side-loading to avoid rod bending. The CA rear clevis mount pairs with standard ISO 6432 mini-cylinder brackets for straightforward installation.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not function as a lock. If air pressure drops or the valve centers, the piston will drift and drop an unsecured load. To maintain vertical position holding, integrate an external pilot-operated check valve or a dedicated rod lock.
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 MI20X330SCA 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 size is 1/8".
No, a standard cylinder drifts when air is lost; the fixed TPU bumpers only decelerate the stroke end and do not act as a brake. Use a pilot check valve for holding. Because this model includes the -S magnet, it supports CMSG, DMSG and EMSG reed or electronic switches.
