About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X550SCA
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 550 mm reach tasks. The 1/8 inch port and M8x1.25 male rod thread feed a robust Ø8 mm piston rod. Because 550 mm exceeds the 500 mm standard maximum, this specific length is manufactured as a made-to-order stroke. The integrated piston magnet allows direct mounting of CMSG, DMSG, or EMSG reed and electronic switches for precise end-position detection.
Its stainless-steel barrel and rod naturally resist mild corrosion, offering a distinct advantage over painted alternatives in damp or washdown settings. The riveted construction incorporates fixed TPU bumper pads to absorb end-of-stroke impact without adjustable cushioning. For practical sizing, plan for a safe working load of roughly 94 N, which comfortably lifts about 8 kg vertically with a 2:1 safety margin. The rear CA pivot clevis simplifies angular mounting alignment on moving machinery.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X550SCA Is Used
Film Roll Diverter
Pushes packaging film rolls between parallel conveyor lanes using the 157 N push force and 550 mm extended reach, with the CA clevis absorbing pivot stress.
Vertical Carton Elevator
Lifts lightweight cardboard cartons weighing up to 8 kg on a packaging line, relying on the stainless build for humid warehouse environments.
Textile Beam Indexer
Shifts textile machinery beams laterally across a 550 mm gap, using CMSG sensors to confirm the extended transfer position.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X550SCA the Right Cylinder?
When sizing this 20 mm bore unit, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N, helping you bracket your exact force requirements. The CA rear clevis accommodates pivoting loads, but remember that a standard cylinder drifts if air pressure drops or the valve centers; the TPU bumpers only decelerate the stroke end and act as neither a lock nor a brake. To hold a vertical load securely, install an external rod lock or a pilot-operated check valve.
Because the 550 mm stroke is non-standard and exceeds the typical 500 mm limit, carefully manage side loads to prevent rod bending. The included -S magnet enables position sensing, and the body accepts standard ISO 6432 mini-cylinder mounting brackets and clevises for straightforward drop-in installation.
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 MI20X550SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It uses a 1/8 inch air port and operates at speeds between 30-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake. For suspended loads, you must use an external rod lock or a pilot-operated check valve.
