Airtac MI16-20 Stainless Steel Mini Cylinder MI20X195SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X195SU is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 195mm 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 MI20X195SU
Generating 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 195 mm travel distance with ease. 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, making it superior to painted alternatives in damp or washdown settings. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.
For practical sizing, plan for roughly 94 N of real work at 0.5 MPa, which translates to lifting an 8 kg part vertically with a safe 2:1 margin. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing. Fixed TPU bumper pads absorb the impact at stroke extremes, while the U back cover provides a 90-degree port orientation to simplify plumbing in tight spaces.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X195SU Is Used
Package Diverting
Actuates a routing flap on a packaging conveyor to sort parcels using the 157 N push force at 0.5 MPa.
Lab Sample Ejection
Pushes processed test tubes out of a centrifuge carousel, utilising the stainless build for cleanroom compatibility.
Tote Positioning
Shifts plastic storage totes laterally on a roller bed with a 195 mm stroke guided by a DMSG sensor.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X195SU the Right Cylinder?
When sizing this 195 mm stroke model, verify your load against the 157 N push and 131.9 N pull figures at 0.5 MPa. If you need less force, the Ø16 bore provides 100.5 N push; for heavier demands, the Ø25 bore steps up to 245.3 N. At 195 mm of travel, watch for rod-bending side loads and ensure proper guiding. The U-style rear cover offers a 90-degree mounting interface. Remember that air loss or a centred valve will cause the piston to drift, as the TPU bumpers only decelerate the end of stroke and act as neither a lock nor a brake. Use a pilot-operated check valve or external rod lock to hold a suspended load.
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 MI20X195SU FAQ
This Ø20 mm bore cylinder features a 1/8 inch port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
No, it uses fixed TPU bumper pads to decelerate at the stroke end, not an adjustable air cushion. It also cannot hold a load if air is lost; the piston will drift. You must add an external rod lock or pilot check valve for position holding.
