Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CM
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MF20X100CM
Generating 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder is built for tight fixture layouts. Because the MF body is shorter than an ISO 6432 cylinder for the same 100 mm stroke, it saves valuable mounting length. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, while the piston's two-way seal retains an oil film for long service life.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end is softened but not adjustably cushioned. Plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a 2:1 safety margin. This CM round-end version uses a 1/8" port and an M8x1.25 male rod thread.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CM Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of a machining fixture using a 100 mm travel distance.
Package Diverting
Actuates a short diverter arm to sort small cartons on a secondary packaging line.
Gripper Actuation
Opens and closes a 20 mm bore pneumatic gripper handling delicate electronic components.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CM the Right Cylinder?
If 157 N is insufficient, step up to the MF25 which provides 245.3 N at 0.5 MPa; as the smallest bore in the MF family, there is no smaller option. Remember that a standard cylinder drifts if air is lost or the valve is centred, so add an external rod lock or pilot check valve to hold a suspended load. This SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG or EMSG position switches. With a 100 mm stroke, keep side-loads minimal to avoid rod bending.
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 MF20X100CM FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. This 20 mm bore cylinder uses a 1/8" air port.
No, this specific SKU does not include a magnet. You must purchase the -S variant to use CMSG, DMSG or EMSG switches. The CM round-end rear cover and fixed TPU bumper pads provide compact, non-adjustable stroke deceleration.
