Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40CM
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40CM is a genuine single acting, push (spring return) round-body mini air cylinder with a Ø16mm bore and 40mm 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 MSI Single Acting Stainless Steel Mini Cylinder MSI16X40CM
Delivering 74.9 N of push force at 0.5 MPa (115.1 N at 0.7 MPa), this AirTAC MSI16X40CM is a single-acting, spring-return mini cylinder. Compressed air extends the Ø6 mm rod, while an internal mechanical spring handles the retraction. Because the spring constantly pulls the rod back, the listed thrust is already net of that spring resistance. This push-only design requires just one 1/8" air line and a single valve port, saving plumbing and compressed air.
Built with a stainless-steel round barrel and piston rod, the riveted construction withstands mild corrosion and routine washdowns. It conforms to the ISO 6432 mounting interface for Ø8-Ø25 bores, dropping directly into standard mini brackets and clevises. For sizing, this bore yields a safe working load of roughly 45 N (about 60% of the 0.5 MPa thrust), translating to a vertical lift of approximately 3.8 kg with a 2:1 safety margin. This specific SKU lacks a magnet and cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches. The rear CM round cover dictates the back-end port and mounting orientation.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40CM Is Used
Small Part Clamping
With a safe working load near 45 N, it securely clamps light machined components during secondary operations, releasing automatically to the retracted rest position on air loss.
Package Diverter Gate
Provides 74.9 N of thrust at 0.5 MPa to push lightweight cardboard cartons off a conveyor line, using the spring return to quickly retract the gate between cycles.
Pin Ejection Stop
Ejects finished molded parts from a fixture using 115.1 N at 0.7 MPa, with the fail-safe retract ensuring the pin clears the mold area when the air supply drops.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40CM the Right Cylinder?
When sizing by thrust, verify your load against the 74.9 N push at 0.5 MPa. If you need less force, the Ø12 bore provides 44.0 N; if your application demands more, step up to the Ø20 bore which outputs 119.5 N. Remember that this single-acting design needs at least 0.2 MPa of supply pressure to overcome the internal return spring—below that threshold the rod will not extend. The 40 mm stroke sits well within the standard 80 mm travel limit for this bore size. Because this unit lacks the -S magnet, it cannot accept magnetic sensors; choose the -S variant if you need end-of-stroke detection. You can pair the body with LB foot, FA flange, SDB pivot-block, or TC trunnion mounts.
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 0.2 – 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 MSI Single Acting Stainless Steel Mini Cylinder MSI16X40CM FAQ
It generates 74.9 N of push force at 0.5 MPa and 115.1 N at 0.7 MPa. It requires a minimum of 0.2 MPa to overcome the internal spring and extend the rod; when air is released, the spring drives the rod back to the retracted rest position.
No, this specific SKU does not have a magnet and cannot accept CMSG, DMSG, or EMSG sensors. You would need the -S variant for position detection. It is a single-acting push cylinder with a stainless steel round body, not a double-acting profile cylinder.
