Airtac MSF Single Acting Mini Cylinder MSF20X30SCAG
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X30SCAG is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 30mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MSF Single Acting Mini Cylinder MSF20X30SCAG
Delivering 117.5 N of push force at 0.5 MPa (181.3 N at 0.7 MPa), this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel with riveted aluminium covers to resist mild washdown. The 20 mm bore houses an 8 mm rod with an M8x1.25 male thread, and the body is deliberately shorter than an ISO 6432 unit of the same size, saving valuable mounting length. A G (BSPP) port thread and a CA rear pivot cover are configured.
Because it is single-acting push with spring return, you only plumb one 1/8" air line to extend the rod; an internal spring retracts it when air drops. The quoted force is already net of that spring, yielding a safe working load of roughly 71 N or a 2:1 vertical lift capacity of about 6 kg. The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X30SCAG Is Used
Light-Duty Clamping
Provides 117.5 N of push force at 0.5 MPa to secure small components during machining, releasing automatically via spring return when air is removed.
Parts Ejection
Uses the single-acting push stroke to knock lightweight finished parts off a conveyor line, relying on the internal spring to reset the rod for the next cycle.
Vertical Lift Gates
Raises small diverters or gates holding up to 6 kg with a 2:1 safety margin, safely defaulting to the closed retracted position if the air supply fails.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X30SCAG the Right Cylinder?
Choose this 20 mm bore when an application needs approximately 71 N of safe push force; if your load requires more, step up to the MSF25 which provides 192.8 N at 0.5 MPa. This single-acting configuration is ideal for simple clamping, ejecting, or gating tasks where the spring naturally retracts the rod on air loss. Ensure your supply stays at or above the 0.2 MPa floor so pressure can overcome the return spring. The included -S magnet allows direct mounting of CMSG/DMSG/EMSG sensors, and the CA pivot back cover suits articulated rod-end installations.
Quick checklist
- ✓ Required force at your working pressure

- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MSF Single Acting Mini Cylinder MSF20X30SCAG FAQ
It generates 117.5 N of push force at 0.5 MPa and 181.3 N at 0.7 MPa. Because it is single-acting with a spring return, the force is net of the spring, and it requires a minimum operating pressure of 0.2 MPa to overcome the spring and extend the rod.
No, the rod cannot be loaded on the return stroke, and the spring only drives it to the retracted rest position on air loss; it will not hold an arbitrary mid-stroke load. The -S magnet allows CMSG/DMSG/EMSG sensors to track end positions, and the SUS304 stainless barrel resists mild corrosion.
