Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40SCA
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40SCA 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 MSI16X40SCA
Delivering a net push force of 74.9 N at 0.5 MPa, this stainless-steel round-body mini cylinder uses compressed air to extend and an internal spring to retract. Because it is a single-acting push type, you only need one 1/8" air line to operate it, saving plumbing and ensuring the rod safely falls back to its retracted rest position if air pressure drops. The Ø6 mm piston rod features an M6x1.0 male thread, and the stainless construction resists mild corrosion and washdown environments.
Built to the ISO 6432 mounting interface, the Ø16 mm barrel drops directly into standard mini brackets and clevises. This specific SKU includes a rear CA pivot cover and a piston magnet (-S) for position sensing. For sizing, this bore yields a safe working load of about 45 N, or a vertical lift capacity of roughly 3.8 kg when applying a 2:1 safety margin. It requires at least 0.2 MPa of supply pressure to overcome the return spring, and fixed TPU bumpers decelerate the stroke ends.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40SCA Is Used
Light-Duty Clamping
Provides a reliable 74.9 N push at 0.5 MPa to hold light workpieces, using the spring return to automatically release the part when air is removed.
Package Diverting
Acts as a compact pop-up gate or diverter arm on a conveyor line, safely retracting out of the product flow path upon air loss.
Part Ejection
Ejects small machined components from a fixture, with the single 1/8" port simplifying valve and plumbing requirements on tight machinery.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X40SCA the Right Cylinder?
When sizing by push force, this Ø16 bore provides 74.9 N at 0.5 MPa. If your application requires less force, the smaller Ø12 bore offers 44.0 N; if you need more, stepping up to the Ø20 bore yields 119.5 N. Remember that supply pressure must stay at or above 0.2 MPa to extend the rod, and the return spring limits the standard stroke to a maximum of 80 mm for this bore size.
This 40 mm stroke configuration arrives with a CA rear pivot cover for clevis mounting and an internal magnet (-S), allowing you to mount CMSG, DMSG, or EMSG sensors directly for end-of-stroke confirmation.
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 MSI16X40SCA FAQ
It delivers a net push force of 74.9 N 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 its retracted rest position.
Yes, because this model includes the -S magnet option, you can mount CMSG, DMSG, or EMSG switches for detection. It is a single-acting push cylinder with a stainless round barrel, not a double-acting profile body.
