Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85U is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 85mm 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 MI16X85U
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The riveted Ø16 mm barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp environments. It features a 1/8" port and an 85 mm stroke.
The integrated U-type back cover mounts at 90 degrees, optimizing spatial layout in tight machine cells. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to safely lifting about 5.1 kg vertically. Fixed TPU bumper pads absorb stroke-end impact, and because this SKU lacks the -S magnet, it cannot host CMSG or DMSG sensors.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85U Is Used
Component Ejection
Pushes machined plastic parts out of a 75 mm deep jig using 100.5 N of thrust at 0.5 MPa.
Package Deflection
Actuates a 90-degree routing gate on a narrow packaging belt where the U-cover side port saves space.
Clamp Actuation
Secures lightweight aluminium extrusions during a cutting cycle, safely lifting parts under 5.1 kg.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85U the Right Cylinder?
If your task requires less than 60 N of push, step down to the Ø12 bore which yields 56.5 N at 0.5 MPa; for heavier drives, the Ø20 bore provides 157.0 N. This 85 mm stroke is well within the 500 mm maximum, keeping rod bending stress low. The 90-degree U rear cover suits side-exit piping, and standard ISO 6432 mounting dimensions ensure it drops right into generic mini-cylinder brackets.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the end of travel rather than locking the rod. Fit an external pilot check valve if your mechanism must hold a vertical load safely during a pressure drop.
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 MI16X85U FAQ
This double-acting cylinder pushes with 100.5 N and pulls with 86.4 N at 0.5 MPa. At 0.7 MPa, push is 140.7 N and pull is 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa, and the air port is 1/8".
No, because this specific SKU lacks the internal magnet. You must select the -S variant to use CMSG, DMSG, or EMSG magnetic switches. The unit uses standard ISO 6432 mounting dimensions but relies on fixed TPU bumper pads rather than adjustable cushions.
