Airtac MF20-25 Stainless Steel Mini Cylinder MF20X120SCA
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X120SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 120mm 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 MF20X120SCA
Generating 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder saves valuable mounting length because its overall body is physically shorter than an equivalent ISO 6432 unit. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion, while the internal two-way seal retains an oil film for extended mechanical life.
Equipped with a built-in magnet for position sensing, the 20 mm bore accepts 1/8" ports and an M8x1.25 male rod thread. The fixed TPU bumper pads soften stroke-end impact without offering adjustable cushioning. Plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a safe 2:1 margin.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X120SCA Is Used
Pivot-Actuated Gate
Uses the CA rear pivot to swing a lightweight diverter flap on a small-bore sorting line, moving packages with its 157 N push capacity.
Electronic Component Ejection
CMSG sensors track the 120 mm stroke to eject populated PCB trays from a test fixture, relying on the compact body to fit tight cell layouts.
Film Roll Tensioner
Applies steady 8 kg vertical tension on a packaging web, utilizing the SUS304 stainless barrel to withstand occasional washdown in food packing areas.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X120SCA the Right Cylinder?
When sizing this 120 mm stroke unit, dropping down is not an option as 20 mm is the smallest available MF bore. Stepping up to the MF25 increases your 0.5 MPa push force to 245.3 N if 157 N proves insufficient. The CA rear pivot cover suits articulated rod-end alignments, and the integrated magnet supports CMSG, DMSG or EMSG switches. For a 120 mm extension, minimize side-loading to prevent rod bending.
Remember that standard bumpers only decelerate the stroke end; they do not function as a brake. If air pressure drops, the piston will drift and drop the load. To secure a vertical weight safely, install an external pilot-operated check valve or a dedicated rod lock.
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 MF20X120SCA FAQ
At 0.5 MPa it pushes with 157 N and pulls with 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. The air port is 1/8 inch.
No, the MF is a JIS-standard cylinder that is simply shorter than an ISO 6432 unit, so ISO brackets will not fit. It uses fixed TPU bumper pads for impact deceleration, not an adjustable air cushion. The CA back cover provides a rear pivot point.
