Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400R is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 400mm 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 MI16X400R
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 400 mm stroke with ease. The Ø16 mm bore uses a 1/8 inch air port and an M6x1.0 male rod thread, while the rear R cover features axial-in porting to keep your pneumatic routing tight against the machine frame. Its stainless barrel and piston rod resist mild corrosion, giving it a real edge over painted alternatives in damp environments.
Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. The riveted body houses fixed TPU bumper pads that decelerate the piston at stroke end. Plan for a safe working load of about 60 N, which lets you lift a 5.1 kg part vertically with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400R Is Used
Package Diverter Arm
Actuates a routing flap on a packaging conveyor, using the 100.5 N thrust to push light cardboard cartons smoothly into a secondary lane.
Vertical Parts Lift
Raises small plastic tote bins between conveyor tiers, safely lifting loads up to 5.1 kg thanks to the calculated 2:1 safety margin.
Textile Loom Tensioner
Adjusts a yarn guide bar over a 400 mm travel distance in a humid textile facility, relying on the stainless rod to resist washdown corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400R the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 generates 56.5 N of push at 0.5 MPa, while stepping up to the Ø20 yields 157.0 N. If your application requires position feedback, you must select the -S magnet variant, as this specific unit cannot accept a reed switch. The 400 mm stroke is well within the 500 mm maximum standard stroke for this bore, though at this length you should carefully manage side loading to prevent rod bending.
Because the fixed TPU bumpers only soften the end-of-stroke impact, this cylinder will not hold a load if air pressure drops or the valve is centred. The piston will drift under load, so incorporate an external rod lock or a pilot-operated check valve if you need vertical position holding. You can mount it using LB foot, FA flange, SDB pivot or TC trunnion hardware.
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 MI16X400R FAQ
This double-acting cylinder has a 1/8 inch air port. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum of 20.5 kgf at 1.0 MPa.
Yes, it uses the ISO 6432 mounting interface for easy compatibility with standard clevises and brackets. However, because this specific SKU lacks the internal magnet, you cannot attach CMSG, DMSG or EMSG magnetic switches without upgrading to the -S variant.
