Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SCM 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 MI16X85SCM
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation with ease. The Ø16 bore uses a 1/8 inch port and a Ø6 mm piston rod with an M6x1.0 male thread. Its round-body barrel and rod are riveted and rolled, avoiding tie-rod bulk while offering mild corrosion resistance for damp production areas.
Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. The -S suffix denotes an internal magnet for CMSG, DMSG or EMSG position switches. For practical sizing, plan for a safe working load of about 60 N, which means it can vertically lift roughly 5.1 kg with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impact across the 85 mm travel.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SCM Is Used
PCB Depaneling Gate
Cycles an 85 mm stroke to open and close a lightweight routing gate on an electronics assembly line, using the 100.5 N push force to clear the cutting path.
Carton Flap Folder
Actuates a folding arm on a small packaging machine, relying on the 86.4 N pull force at 0.5 MPa to tuck corrugated flaps before taping.
Lab Sample Diverter
Pushes a diverter arm to route vials into a testing carousel, where the stainless build withstands daily wipe-downs and the CMSG sensor confirms the shift.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X85SCM the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 MI generates 56.5 N of push at 0.5 MPa, while the larger Ø20 MI provides 157.0 N, giving you clear scaling if your load shifts. The CM round end cover suits specific rear mounting orientations, complementing available LB foot, FA flange, SDB pivot and TC trunnion options. Because this is an 85 mm stroke, keep side-loads minimal to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI16X85SCM FAQ
This Ø16 bore cylinder features a 1/8 inch port and generates 100.5 N push / 86.4 N pull at 0.5 MPa, and 140.7 N push / 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, the base MI uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion (see the MIC variant for that). It also does not hold position on air loss; use an external rod lock or pilot check valve for load holding.
