Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 125mm 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 MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CA
Delivering 157 N of push force at 0.5 MPa, this double-acting round-body mini cylinder is built for rapid actuation where space is tight. The MFC20X125CA features a 20 mm bore, 125 mm stroke, and a CA rear pivot cover. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same bore and stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
The defining feature is the variable air cushion at both ends; a needle valve lets you dial in the deceleration to absorb high-speed end-of-stroke shock, protecting the load and cutting noise. Based on the 0.5 MPa push rating, it handles a safe working load of about 94 N, or lifts roughly 8 kg vertically with a 2:1 margin. This non-magnet SKU cannot host a sensor; adding the -S option enables CMSG, DMSG, or EMSG switches. It uses a 1/8" port and an 8 mm rod with an M8x1.25 male thread.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CA Is Used
Light-Part Ejection
Shoots small plastic or stamped parts out of a fixture at speed; the tuned air cushion prevents the 8 mm rod from slamming the end cap, protecting the 125 mm stroke mechanism.
Flap Folding
Pivots carton flaps via the CA rear mount; the 157 N push force easily moves light cardboard while the adjustable cushion ensures quiet, damage-free stops.
Small Diverting
Pushes lightweight parcels off a belt; the compact JIS body fits into tight transfer gaps where a longer ISO 6432 unit would not clear the frame.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CA the Right Cylinder?
If 94 N of safe working load is insufficient, step up to the MFC25, which provides 245.3 N at 0.5 MPa; since 20 mm is the smallest available MFC bore, there is no smaller option. The adjustable air cushion is essential when cycling at high speeds or moving delicate loads that cannot tolerate a hard impact. Remember that the cushion only decelerates the piston near the stroke end—it is not a brake. Because this plain cylinder drifts when air pressure drops or a valve centers, use an external rod lock or pilot-operated check valve for suspended loads. Mounting is handled via the built-in CA pivot, and you must specify the -S magnet version if you need position sensing.
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 MFC Cushioned Stainless Steel Mini Cylinder MFC20X125CA FAQ
This 20 mm bore cylinder has a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot host a sensing switch. You must purchase the -S variant to use CMSG, DMSG, or EMSG sensors. The SUS304 stainless build resists mild corrosion, and the needle-set variable air cushion decelerates the piston at stroke end to reduce shock, but it does not lock or hold the load.
