Airtac MSF Single Acting Mini Cylinder MSF20X30CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X30CM 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 MSF20X30CM
Delivering 117.5 N of push force at 0.5 MPa, this MSF20X30CM mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/8" port, which simplifies valve requirements and ensures the rod fails to the retracted position on air loss. The quoted force is already net of the spring, meaning the internal mechanism does not rob your effective output. For practical clamping tasks, expect a safe working load of about 71 N, or a vertical lift capacity near 6 kg with a 2:1 safety margin.
Built as a JIS-standard round-body unit, it features a SUS304 stainless barrel and riveted aluminium covers that resist mild corrosion and washdown environments. This construction is notably shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. The unit comes with a CM round-end rear cover, fixed TPU bumper pads for end-of-stroke deceleration, and no internal magnet. Without the -S option, this specific SKU cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X30CM Is Used
Spring-Return Clamping
Provides reliable 71 N clamping force that automatically releases to the retracted position if the air supply drops.
Compact Part Ejection
Fits into tight machinery spaces thanks to a body length shorter than ISO 6432 equivalents, ejecting light parts with 117.5 N.
Vertical Lift Gates
Pushes small gates or diverters upward with a 6 kg lift capacity, relying on the internal spring to safely lower the load.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X30CM the Right Cylinder?
When sizing this 20 mm bore model, verify your application needs the 117.5 N @0.5 MPa output (181.3 N @0.7 MPa). If your load requires less force, note there is no smaller MSF bore available. If you need more push, step up to the MSF25, which provides 192.8 N @0.5 MPa. Maintain a minimum operating pressure of 0.2 MPa to overcome the return spring, and choose LB foot, FA flange, SDB pivot, or TC trunnion mounts to fit your frame. Because this SKU lacks the -S magnet, position sensing is not possible; add the -S variant if you require CMSG or DMSG switches.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ 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 MSF20X30CM FAQ
The single-acting push force is 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa. Because it is spring-return, you must supply at least 0.2 MPa to overcome the spring, with a maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The spring also means it cannot hold a mid-stroke load on air loss.
