Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160U
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160U 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 MI20X160U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust light-duty tasks. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, outlasting painted alternatives in damp or washdown settings. Built-in fixed TPU bumper pads absorb stroke-end impact without requiring adjustment.
For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which equates to lifting about 8 kg vertically with a safe 2:1 margin. The U suffix denotes a 90-degree rear cover, orienting the supply port sideways for tight installations. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160U Is Used
Package Deflection
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, surviving occasional washdown thanks to the stainless build.
Textile Loom Tensioning
Utilises the 90-degree U rear cover to fit within a narrow loom frame, maintaining thread tension across a 160 mm travel distance.
Bin Lid Actuation
Lifts a hopper lid weighing approximately 8 kg vertically, operating safely within the calculated 2:1 load margin at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X160U the Right Cylinder?
When sizing this 160 mm stroke unit, consider the neighbouring bores: the Ø16 generates 100.5 N push while the Ø25 provides 245.3 N at 0.5 MPa. If your payload drops when air is lost, note that the TPU bumpers only decelerate the stroke end and do not function as a lock; an external pilot check valve or rod lock is required to hold a suspended load. The 160 mm extension demands attention to side loading, so ensure rigid front mounting or a guide to prevent rod bending. Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.
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 MI20X160U FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8 inch.
No, this specific SKU lacks the internal magnet. You must select the -S variant to use CMSG, DMSG or EMSG switches. The unit conforms to ISO 6432 mounting dimensions and uses fixed TPU bumper pads rather than an adjustable air cushion.
