Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160R
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160R is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 160mm 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 MI20X160R
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 160 mm stroke with a 1/8 inch rear axial port. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp work areas. Its ISO 6432 mounting interface drops directly into standard mini-cylinder brackets and clevises.
Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. For real work, plan for about 94 N of usable load at 0.5 MPa, which translates to lifting roughly 8 kg vertically with a safe two-to-one margin. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to the -S version.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160R Is Used
Package Diverter Gate
Pushes a routing flap on a packaging line, using the 157 N thrust to deflect moderate-weight cartons without stalling.
Textile Loom Tensioner
Cycles a yarn guide arm through its 160 mm travel, where the stainless build resists humid manufacturing environments.
Bin Lid Actuator
Lifts an access hatch on a sorting hopper, comfortably managing the 8 kg vertical lift capacity at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160R the Right Cylinder?
This 20 mm bore sits neatly between the 12 mm class (56.5 N push at 0.5 MPa) and the 25 mm class (245.3 N), making it a solid middle ground when 160 mm of travel is needed. The 1/8 inch porting and M8x1.25 male rod thread match standard mini-cylinder hardware. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion blocks alongside the R back cover.
Because the 160 mm stroke extends the Ø8 mm rod fairly far, watch for side-load forces that could induce rod bending. A plain MI will drift if air pressure drops, as the TPU bumpers only decelerate the end of travel rather than locking the load. To hold a vertical position securely, fit an external rod lock or a pilot-operated check valve.
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 MI20X160R FAQ
The 1/8 inch ported bore provides 157 N push and 131.9 N pull at 0.5 MPa, rising to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this SKU does not have a magnet. To use CMSG, DMSG or EMSG switches, you must specify the -S variant. The R back cover provides an axial-in port, and it uses standard ISO 6432 mounting dimensions.
