About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with ease. The riveted barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Its ISO 6432 mounting dimensions mean it drops straight into standard mini-cylinder brackets and clevises.
For actual work, plan for roughly 94 N of usable load at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin. The CA rear pivot cover allows straightforward clevis mounting. 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 MI20X150CA Is Used
Bottling Line Diverter
Routes plastic bottles on a washdown conveyor using the 157 N push force, with the stainless rod resisting moisture from routine cleaning.
Small Parts Ejector
Pushes machined aluminium brackets out of a CNC fixture over a 150 mm travel, comfortably handling the 8 kg vertical lift equivalent.
Carton Flap Folder
Folds corrugated cardboard flaps on a packaging line, using the CA pivot clevis to accommodate the angular arc during the stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X150CA the Right Cylinder?
When sizing this 20 mm bore, the adjacent 16 mm option yields 100.5 N of push at 0.5 MPa, while the larger 25 mm bore provides 245.3 N, letting you step up or down precisely. The 150 mm stroke is well within the 500 mm maximum standard limit, though at this extension you should watch for side loads to prevent rod bending. Air enters via the 1/8" port, and the male M8x1.25 rod thread simplifies tooling attachment.
Remember that a standard MI relies solely on fixed TPU bumper pads to decelerate at the stroke end; it is not an adjustable air cushion. If air pressure drops or the valve is centred, the piston will drift, so fit an external rod lock or pilot check valve if you need to suspend a load safely.
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 MI20X150CA FAQ
This 20 mm bore cylinder features a 1/8" air 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, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be fitted. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
