Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 450mm 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 MI20X450CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 450 mm strokes with a CM round rear cover. 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. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without adjustable cushioning.
Because the 157 N rating leaves a margin for friction, plan for roughly 94 N of actual work at 0.5 MPa. That translates to lifting about 8 kg vertically with a safe 2:1 factor. The Ø20 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CM Is Used
Diverting Gate Actuation
Pushes lightweight sorting flaps on packaging lines using its 157 N thrust and 450 mm travel to redirect cartons between lanes.
Vertical Parts Ejection
Lifts approximately 8 kg moulded plastic components out of a fixture, relying on the stainless rod to resist factory humidity.
Sample Tray Extension
Extends a laboratory testing tray to a full 450 mm reach, where the compact riveted round body fits tight equipment frames.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X450CM the Right Cylinder?
If 157 N at 0.5 MPa is too much, the Ø16 bore drops the push force to 100.5 N; if you need more power, stepping up to the Ø25 bore yields 245.3 N. This 450 mm stroke sits well within the 500 mm standard limit for this bore, but at that length you must carefully manage side loading to prevent rod bending. The CM round end cover dictates a specific rear mounting and port orientation.
Without an -S suffix, this specific SKU lacks a magnet and cannot host CMSG, DMSG or EMSG switches. If position sensing is required, select the -S variant. Remember that venting the air supply causes the piston to drift, as the TPU bumpers only soften the stroke end rather than locking the load; use a pilot check valve or external rod lock to hold a vertical 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 MI20X450CM 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, this SKU lacks the -S suffix, so it has no internal magnet and cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing.
