Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CASDB
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CASDB is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 100mm 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 MI20X100CASDB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. Fixed TPU bumper pads absorb the impact at stroke ends, and the riveted construction keeps the housing compact.
Because the 157 N rating is a theoretical maximum, plan for a safe working load of about 94 N to account for friction and air pressure drops. That translates to lifting a 16 kg part, but applying a 2:1 safety margin means you should keep vertical loads around 8 kg. This SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches without upgrading to the -S variant.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CASDB Is Used
Package Diverter Arm
Swings a lightweight sorting gate on a packaging line, using the CA clevis to pivot smoothly while pushing parcels under the 94 N safe working limit.
Damp Environment Gate
Actuates a drainage valve or access hatch in a humid washdown area where the stainless steel barrel prevents the mild corrosion seen on standard aluminium bodies.
Parts Ejector Mechanism
Pushes machined components off an assembly fixture, relying on the SDB pivot block to accommodate minor misalignment during the 100 mm ejection stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CASDB the Right Cylinder?
When sizing this 100 mm stroke actuator, check both neighbours: the Ø16 bore provides 100.5 N of push at 0.5 MPa, while the Ø25 bore offers 245.3 N if your payload exceeds the safe 94 N working load. The included CA rear clevis and SDB pivot block allow self-aligning mounting, which is critical for absorbing side loads on a 100 mm stroke. If your mechanism requires position feedback, select the -S magnet version instead, as this base model cannot host a sensor.
Remember that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as an adjustable air cushion. Furthermore, if air pressure drops or the control valve centres, the rod will drift and drop the load. To prevent unintended movement on vertical lifts, install 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 MI20X100CASDB FAQ
This Ø20 mm bore cylinder features a 1/8" 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 force of 32 kgf at 1.0 MPa.
Yes, the Ø20 mm bore uses the ISO 6432 mounting interface, so it drops into standard mini-cylinder brackets and clevises. However, this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG or EMSG switches unless you purchase the -S variant.
