Airtac MSF Single Acting Mini Cylinder MSF20X10CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X10CM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MSF20X10CM
Delivering a net push of 117.5 N at 0.5 MPa, this 20 mm bore mini cylinder uses air to extend the rod and an internal spring to retract it. The MSF20X10CM features a JIS-standard round-body construction with a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same size. It includes a CM round-end rear cover and a 1/8" port.
Because it is single-acting, you only plumb one air line, which simplifies valve requirements and ensures the rod fails to the retracted position upon air loss. The quoted force is already net of the return spring, yielding a safe working load of roughly 71 N or a 2:1 vertical lift capacity of about 6 kg. This non-magnet SKU cannot host position sensors; adding an -S variant enables CMSG, DMSG, or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X10CM Is Used
Light-Duty Clamping
Apply 71 N of safe holding force to secure small plastic housings during a machining operation, releasing automatically on air loss.
Parts Ejection
Push lightweight finished components off a conveyor belt with a 10 mm stroke, relying on the internal spring to keep the rod clear during transit.
Compact Gating
Actuate a short diverter gate in a packaging line where the shorter JIS body saves valuable mounting length compared to ISO 6432 alternatives.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X10CM the Right Cylinder?
For light-duty clamping or ejecting at 0.5 MPa, this 20 mm bore provides 117.5 N of push force. If your application requires less power, note there is no smaller MSF bore, so you must throttle the pressure down to the 0.2 MPa minimum floor. If you need more force, step up to the MSF25, which delivers 192.8 N at 0.5 MPa. The fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range.
Select this configuration for spring-return tasks where space is tight. The CM round-end cover suits direct pivot mounting, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets. Remember that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG sensors without switching to an -S model.
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 MSF20X10CM FAQ
This 20 mm bore cylinder provides a net push force of 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 internal spring and extend the rod.
No, this specific SKU does not include a magnet and cannot host CMSG, DMSG, or EMSG switches. You must select an MSF model with the -S suffix for position sensing capabilities.
