Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CM
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CM 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 MF20X10CM
Generating 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles very short 10 mm strokes with precision. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length in compact assemblies.
The unit features a CM round-end rear cover and fixed TPU bumper pads that soften stroke-end impact without offering adjustable cushioning. Plan for a safe working load of about 94 N, which easily lifts an 8 kg part vertically with a 2:1 margin. Note that this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CM Is Used
Micro-Clamping Jigs
Secures delicate electronic components in PCB routing stations, using the 94 N safe working load to grip without crushing the parts.
Short Ejector Pins
Ejects small plastic mouldings from tight tooling cavities where the 10 mm stroke and compact JIS body length fit perfectly.
Package Diverter Gate
Actuates a lightweight routing flap on a packaging line, lifting roughly 8 kg of gate mass vertically with a safe 2:1 margin.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CM the Right Cylinder?
When sizing this 20 mm bore actuator, consider the adjacent MF25 bore if you need more power, as it provides 245.3 N of push at 0.5 MPa compared to the 157 N offered here. There is no smaller MF bore available, making this the most compact option in the family for light-duty clamping. With a very short 10 mm stroke, side-load and rod-bending stresses are minimal, but ensure the male M8x1.25 thread aligns perfectly with your load.
Because the base MF uses fixed TPU bumpers rather than an adjustable cushion, it only decelerates the stroke end rather than braking the load. A plain cylinder will drift and drop its payload if air pressure is lost or the valve is centred, so you must integrate an external rod lock or a pilot-operated check valve for secure vertical load holding.
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 MF20X10CM FAQ
This 20 mm bore cylinder features a 1/8" air port and an M8x1.25 male rod thread. It generates 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 force of 32 kgf at 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 CM round-end rear cover and fixed TPU bumpers provide compact mounting and impact absorption without adjustable cushioning.
