Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCA 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 MI16X400SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles long 400 mm linear displacements with a CA pivot clevis. The riveted round body shrugs off mild corrosion, giving it a real edge over painted alternatives in damp production areas. Because the bore is Ø16, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets.
The built-in -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb the end-of-stroke impact. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin. Air connects via a 1/8 inch port, and the M6x1.0 male rod thread secures your tooling.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCA Is Used
Carton Diverter Arm
Pushes lightweight cardboard cartons across a packaging line using the 100.5 N thrust and 400 mm reach.
Parts Ejection Chute
Sweeps finished moulded plastic parts out of a machining cell, relying on the stainless body for damp resistance.
Pneumatic Flap Lowering
Deploys a sorting flap 400 mm downward, using the CA clevis to pivot smoothly under gravity.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SCA the Right Cylinder?
When sizing this 16 mm bore, compare it against neighbours: the Ø12 generates 56.5 N push, whereas the Ø20 steps up to 157.0 N at 0.5 MPa. This model includes the CA rear pivot cover, so pair it with a matching clevis pin for angular alignment. The -S magnet is essential if your control system requires CMSG, DMSG or EMSG sensor feedback.
At a 400 mm stroke, the Ø6 mm rod extends far from the body, making side-load alignment critical to prevent premature seal wear and rod bending. Note that venting the air causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. Use a pilot-operated check valve or external rod lock if you must hold position vertically.
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 MI16X400SCA FAQ
This 16 mm bore cylinder uses 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 force of 20.5 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. For vertical load holding, install an external rod lock or a pilot-operated check valve.
