Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X30SCM
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X30SCM is a genuine single acting, push (spring return) round-body mini air cylinder with a Ø20mm bore and 30mm 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 MSI20X30SCM
Delivering a net push force of 119.5 N at 0.5 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 inch air line, which saves on piping and valves. If air pressure drops, the spring automatically pulls the rod back to its retracted rest state, providing a fail-safe motion. The Ø20 mm bore uses an M8x1.25 male rod thread and fixed TPU bumper pads to soften the stroke end.
Built with a riveted stainless barrel and rod, it resists mild corrosion and washdown environments while conforming to the ISO 6432 mounting interface for easy bracket interchange. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. For sizing, a practical safe working load is about 72 N, or roughly 6.1 kg of vertical lift with a 2:1 margin. Note that a minimum of 0.2 MPa is required to overcome the return spring before extension begins.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X30SCM Is Used
Part Ejection
Uses the 119.5 N push stroke to kick machined parts off a conveyor, with the spring ensuring the ejector retracts clear on air loss.
Light Clamping
Applies a safe holding force of about 72 N to secure light components during an assembly process, releasing automatically when air is removed.
Carton Gating
Extends the rod to act as a temporary stop for packaging flow, safely retracting to release items when the single air line is vented.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X30SCM the Right Cylinder?
When sizing by push force, this 20 mm bore yields 119.5 N at 0.5 MPa. If you need less force, stepping down to a 16 mm bore gives 74.9 N; if your application requires more push, stepping up to a 25 mm bore provides 190.3 N. Always factor in the fail-safe retract behavior, remembering the spring only drives the rod to the retracted position and will not hold a mid-stroke load. You must supply at least 0.2 MPa to beat the spring. The 30 mm stroke sits well within the 80 mm standard limit for this bore. This specific configuration includes the CM round rear cover for port orientation and the -S magnet for position sensing.

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 MSI20X30SCM FAQ
This single-acting push cylinder delivers 119.5 N of force at 0.5 MPa and 182.3 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. When air is released, the spring drives the rod back to its normally retracted rest state.
Yes, the -S suffix means this cylinder has a built-in piston magnet and is compatible with CMSG, DMSG, and EMSG reed or electronic switches. The stainless steel round-body construction uses a 1/8 inch port and fixed TPU bumper pads, distinguishing it from non-magnetized or adjustable-cushion variants.
