Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SCM
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SCM is a genuine single acting, push (spring return) round-body mini air cylinder with a Ø20mm bore and 60mm 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 MSI20X60SCM
Delivering 119.5 N of push force at 0.5 MPa (182.3 N at 0.7 MPa), this stainless-steel round-body mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is a single-acting PUSH type, you only need one 1/8" air line, saving plumbing and air consumption. The Ø20 mm bore uses an M8x1.25 male rod thread and a Ø8 mm piston rod. This specific configuration includes a CM round back cover for straightforward port orientation and an -S piston magnet for position sensing.
The stainless barrel and rod resist mild corrosion and washdown environments. A practical computed buyer insight: the safe working load is roughly 72 N (about 60% of the 0.5 MPa push figure), which translates to clamping or vertically lifting about 6.1 kg with a 2:1 safety margin. Note that the listed forces are already net of the return spring. It conforms to the ISO 6432 mounting interface for easy bracket interchange, and the -S magnet enables CMSG, DMSG, or EMSG sensors. Fixed TPU bumper pads soften the stroke ends.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SCM Is Used
Part Ejection
Pushes finished parts off a conveyor with 119.5 N of extend force, using the spring return to safely retract the ejector pin when air is removed.
Carton Gating
Acts as a spring-return stop gate on a packaging line, holding a box until air pressure extends the Ø8 mm rod to release it down the roller track.
Press-to-Hold Clamping
Secures light workpieces during machining, applying a safe working load of roughly 72 N and automatically unclamping back to the retracted rest state on air loss.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SCM the Right Cylinder?
When sizing this single-acting push cylinder, compare the 119.5 N @0.5 MPa output against your load. If you need less force, step down to the Ø16 bore which provides 74.9 N; if you require more, step up to the Ø25 bore offering 190.3 N. Remember that a minimum of 0.2 MPa operating pressure is required to overcome the internal return spring—below that, the rod will not extend. The 60 mm stroke sits safely within the 80 mm standard spring-limited travel for this bore. Mounting options include LB foot, FA flange, SDB pivot-block, and TC trunnion, and the included -S magnet allows for drop-in sensor installation.
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 MSI20X60SCM FAQ
It delivers a push force of 119.5 N at 0.5 MPa and 182.3 N at 0.7 MPa. A minimum of 0.2 MPa is required to overcome the internal spring; if air drops below this or is lost, the spring retracts the rod to its fail-safe rest position.
The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG position sensors. As a single-acting push cylinder, it uses one 1/8" port to extend and relies on the spring to retract, meaning it will not hold a mid-stroke load without continuous air pressure.
