Airtac MSF Single Acting Mini Cylinder MSF20X30CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X30CA 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 MSF20X30CA
Delivering 117.5 N of push force at 0.5 MPa, this AirTAC MSF20X30CA mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/8 inch port, simplifying valve requirements. The SUS304 stainless round-body barrel is riveted to aluminium covers, resisting mild washdowns while keeping the overall envelope shorter than an ISO 6432 unit of identical bore and stroke.
The quoted output is already net of the return spring, yielding a safe working load of roughly 71 N or a 6 kg vertical lift with a 2:1 margin. This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors. It features fixed TPU bumper pads for end-of-stroke deceleration and a CA rear pivot cover for direct mounting.

Theoretical Output Force (Ø20mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 117.5 N |

Where the Airtac MSF Single Acting Mini Cylinder MSF20X30CA Is Used
Small Part Clamping
Apply 71 N of safe holding force to secure light plastic housings during a secondary machining operation.
Package Ejector
Push lightweight cartons off a belt line; the spring automatically retracts the rod clear of the conveyor when air stops.
Divert Gate Actuation
Extend a 30 mm stroke to pivot a sorting guide, relying on the fail-safe retracted position during power loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X30CA the Right Cylinder?
If your clamp or eject mechanism needs less push, there is no smaller MSF bore; stepping up to the MSF25 provides 192.8 N at 0.5 MPa. Remember the 0.2 MPa pressure floor—below that, the internal spring wins and the rod will not extend. Match your mounting using the CA pivot, or select LB foot, FA flange, or TC trunnion accessories. For position feedback, you must specify the -S magnet version to use CMSG, DMSG, or EMSG 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 MSF20X30CA 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, it requires a minimum operating pressure of 0.2 MPa to overcome the spring and extend the rod.
No. On air loss, the spring drives the rod to the retracted position; it cannot hold an arbitrary mid-stroke load. Also, this SKU lacks a magnet, so it cannot take CMSG, DMSG, or EMSG sensors—you need the -S variant for position feedback.
