Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 700mm 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 MI20X700SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding extended-reach tasks. The 700 mm stroke is a non-standard, made-to-order length that exceeds the 500 mm maximum standard for this Ø20 bore, providing extra travel for deep-reaching equipment. A built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position detection, while the rear CM round cover offers a clean, compact mounting footprint.
The riveted stainless barrel and rod resist mild corrosion and washdown, outperforming painted alternatives in damp environments. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for a safe working load of about 94 N (roughly 60% of the 0.5 MPa rating), which means it can lift an 8 kg part vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the end-of-stroke impact, operating reliably at speeds of 30-800 mm/s.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCM Is Used
Extended Transfer Push
Uses the 700 mm stroke to push heavy cardboard cartons across a wide transfer junction on a packaging line, utilizing the 157 N thrust at 0.5 MPa.
Deep Bin Extraction
Reaches deep into storage racks to extract 8 kg tote bins, relying on the stainless construction to resist humid warehouse conditions.
Textile Beam Shift
Shifts large textile beams laterally between processing stations, where the CM rear cover and ISO 6432 dimensions allow simple bracket integration.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X700SCM the Right Cylinder?
When sizing this actuator, compare its 157 N push force at 0.5 MPa against the adjacent bores: step down to a Ø16 for 100.5 N, or up to a Ø25 for 245.3 N if your system needs more thrust. This SKU includes the -S magnet for electronic or reed sensors and features a 1/8" port. The CM round end cover dictates the rear profile for your mounting arrangement.
Because the 700 mm stroke greatly exceeds the 500 mm standard, carefully manage rod side-loading to prevent premature bending or seal wear. Furthermore, a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the TPU bumpers only decelerate the stroke end and act as neither a brake nor a lock. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MI20X700SCM FAQ
This Ø20 bore cylinder features a 1/8" air port and an M8x1.25 male rod thread. The double-acting thrust outputs are 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 of 32 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not function as a locking brake. For vertical loads, you must install an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to confirm position.
