Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 100mm 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 MI20X100SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 100 mm stroke with a Ø8 mm piston rod. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Equipped with a built-in magnet, it accepts CMSG, DMSG, or EMSG switches for position sensing.
It features fixed TPU bumper pads to decelerate the stroke end and a CM round rear cover for clean port orientation. The 1/8" port feeds air to both chambers, operating at 30-800 mm/s. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it lifts roughly 8 kg vertically with a safe 2:1 margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 157 N push force to redirect medium-weight cartons without stalling.
Small Press Ejection
Kicks stamped aluminum parts out of a die area, relying on the fixed TPU bumpers to absorb end-of-stroke impact during rapid cycling.
Vertical Parts Lift
Raises lightweight plastic totes 100 mm using the M8x1.25 rod thread, safely lifting loads around 8 kg with a proper 2:1 safety margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SCM the Right Cylinder?
When sizing this 20 mm bore, the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N. This model sits perfectly in the middle for medium-duty tasks. Because the base MI uses fixed TPU bumper pads rather than an adjustable air cushion, consider the MIC variant if you need variable deceleration for high-speed cycling.
The CM round end cover pairs with standard LB foot, FA flange, or TC trunnion mounts via the ISO 6432 mounting interface. The included -S magnet enables electronic or reed sensors. Remember that a plain double-acting cylinder drifts if air pressure drops or the valve is centred; to hold a vertical load safely, add an external rod lock or pilot-operated check valve rather than relying on the bumpers.
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 MI20X100SCM FAQ
This 20 mm bore cylinder uses a 1/8" air port. It generates 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 force of 32 kgf at 1.0 MPa.
No, the base MI uses fixed TPU bumper pads that decelerate the piston at the stroke ends but do not offer adjustable cushioning. It also conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets.
