Airtac MSF Single Acting Mini Cylinder MSF20X50CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X50CM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 50mm 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 MSF20X50CM
Delivering 117.5 N of push at 0.5 MPa (181.3 N at 0.7 MPa), this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers to save mounting length compared to ISO 6432 units. As a single-acting push type, air extends the rod through the 1/8" port while an internal spring retracts it, meaning you only pipe one line and the cylinder defaults to the retracted position on air loss. The quoted forces are already net of the spring, which requires a 0.2 MPa floor to overcome.
For practical sizing, a safe working load is roughly 71 N, or about 6 kg of vertical lift with a 2:1 margin. This CM-cover version features a round rear end, and because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position sensors. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable cushion.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X50CM Is Used
Light-Duty Clamping
Provides a safe 71 N holding force for securing small plastic or cardboard components during a secondary machining process.
Part Ejection
Pushes lightweight finished parts off a conveyor belt, with the spring ensuring the rod retracts safely when air is removed.
Vertical Lift Gate
Raises a small 6 kg分流 gate against gravity using 0.5 MPa air, relying on the spring to pull it closed at rest.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X50CM the Right Cylinder?
If your clamping or ejecting task needs less push, there is no smaller MSF bore; stepping up to the MSF25 provides 192.8 N at 0.5 MPa. Ensure your supply stays at or above the 0.2 MPa minimum, otherwise the return spring will overpower the air and prevent extension. Mounting is flexible via LB foot, FA flange, SDB pivot, or TC trunnion brackets, and if you need position feedback, select an -S magnet variant instead of this non-sensing 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 MSF20X50CM FAQ
The single-acting push force is 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa, measured net of the return spring. You must supply at least 0.2 MPa of air pressure to overcome the spring and extend the rod.
No, this SKU does not include a magnet, so CMSG, DMSG, or EMSG switches will not function. You must select an -S variant for position sensing. The spring also drives the rod to the retracted position on air loss, so it cannot hold a mid-stroke load.
