Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CM 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 MI20X100CM
Delivering 157 N of push force at 0.5 MPa, the AirTAC MI20X100CM is a double-acting round-body mini cylinder built for compact automation. Its stainless-steel barrel and piston rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb impact at the stroke ends. A 100 mm stroke and 1/8 inch port provide ample flow for rapid cycling.
For practical sizing, plan for about 94 N of real work at 0.5 MPa, which safely lifts an 8 kg part vertically with a 2:1 margin. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches. The CM round rear cover offers a clean back-end profile, and the Ø20 mm body conforms to ISO 6432 mounting dimensions for easy bracket integration.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CM Is Used
Package Diverting
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, where the stainless body withstands occasional washdowns.
Small Part Ejection
Ejects moulded plastic components from a press using the 100 mm stroke, relying on the fixed TPU bumpers to quietly absorb end-of-travel impact.
Clamp Actuation
Secures aluminium brackets during a machining step, safely applying around 94 N of working force without marking the raw material.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100CM the Right Cylinder?
When sizing this 20 mm bore, compare it against its neighbours: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, while the larger Ø25 provides 245.3 N. Choose the Ø20 when you need roughly 157 N of thrust but want to keep the physical envelope tight. This model carries a 100 mm stroke, which is well within the 500 mm maximum; however, always verify side loading to prevent rod bending on longer extensions.
Remember that a standard double-acting cylinder drifts when air is removed or a valve centres, as the fixed TPU bumpers only decelerate the end of travel without locking the piston. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Furthermore, this specific configuration omits the magnet, so position sensing is unavailable unless you upgrade to an -S variant.
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 MI20X100CM FAQ
This 20 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.
The Ø20 mm body uses ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder foot, flange and clevis brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG magnetic switches.
