Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CM is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 70mm 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 MI20X70CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 70 mm stroke with a compact riveted construction. The Ø20 mm bore operates on a 1/8 inch port and features a CM round rear cover for straightforward port and mounting orientation. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
Because it conforms to ISO 6432 mounting dimensions, this unit drops directly into standard mini-cylinder brackets and clevises. Plan for a safe working load of about 94 N, which lets you lift a real part weight of roughly 8 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb the stroke-end impact, decelerating the piston smoothly without the complexity of adjustable cushioning.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CM Is Used
Package Diverting Gate
Actuates a lightweight routing flap on a packaging conveyor, using the 157 N thrust to push cardboard cartons onto secondary lines at speeds up to 800 mm/s.
Damp Environment Ejector
Ejects machined plastic parts from a coolant-washed zone, leveraging the stainless steel barrel and rod to prevent mild corrosion where painted cylinders fail.
Vertical Parts Lift
Raises small component trays in an assembly cell, safely lifting loads around 8 kg thanks to the 2:1 safety margin on the 0.5 MPa push rating.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X70CM the Right Cylinder?
When sizing this 70 mm stroke unit, verify your payload against the 157 N push at 0.5 MPa. If you need less force, the Ø16 bore provides 100.5 N; stepping up to the Ø25 bore yields 245.3 N. The CM round end cover pairs with LB foot, FA flange, SDB pivot, and TC trunnion brackets. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position sensors. You would need the -S variant for switch mounting.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the fixed TPU pads only soften the end of travel rather than locking the rod. For suspended loads that must hold position, install an external rod lock or a pilot-operated check valve. Additionally, keep the 70 mm stroke side-loads minimal to prevent rod bending and premature seal wear.
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 MI20X70CM FAQ
This Ø20 mm bore cylinder features a 1/8 inch port and an M8x1.25 male rod thread. The double-acting thrust is 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, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant (MI20X70CM-S) for sensor compatibility. It uses fixed TPU bumper pads for end-of-stroke deceleration and follows ISO 6432 mounting dimensions for standard brackets.
