Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10SCM
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10SCM is a genuine double acting 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 MF20-25 Stainless Steel Mini Cylinder MF20X10SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder uses a SUS304 stainless barrel with riveted aluminium covers to resist mild corrosion. Because the riveted rolling-packed structure is shorter than an ISO 6432 cylinder of the same bore and stroke, it saves valuable mounting length in tight machinery. The 1/8" port and 10 mm stroke make it ideal for very compact clamping.
The built-in piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact, while the two-way seal retains an oil film for long life. Plan for about 94 N of actual work at 0.5 MPa, which safely lifts an 8 kg part vertically with a 2:1 margin.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10SCM Is Used
Micro-Clamping Jigs
Ideal for locking small electronic components onto a PCB routing fixture where the 10 mm stroke and 94 N safe working load provide precise, short-travel holding without consuming valuable tooling space.
Ejector Gates
Perfect for pushing lightweight plastic moulded parts out of a sub-25 mm forming cavity, utilising the 8 kg vertical lift capacity to positively eject parts before the main conveyor belt engages.
Short-Stroke Positioning
Used in packaging machinery to index thin foil wrappers exactly 10 mm before sealing, leveraging the compact JIS body length to fit between tight guide rails.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10SCM the Right Cylinder?
When sizing this 20 mm bore actuator, consider the next size up: the MF25 provides 245.3 N of push at 0.5 MPa if your clamping force is insufficient. As the smallest bore in the MF series, there is no smaller option, so if 94 N of safe working load is too low, stepping up to the 25 mm bore is required. The CM round-end back cover provides a specific pivot mounting interface.
Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG sensors. Remember that a standard cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To hold a load securely, add an external rod lock or a pilot-operated check valve.
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 0.15 – 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 MF20-25 Stainless Steel Mini Cylinder MF20X10SCM FAQ
This 20 mm bore cylinder features a 1/8" air port and an 8 mm rod with an M8x1.25 male thread. The double-acting thrust is 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
The MF is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 cylinder for the same bore and stroke, so ISO 6432 brackets will not fit. However, the -S suffix indicates a built-in magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly for position detection.
