Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 300mm 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 MFC20X300SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder integrates a needle-adjustable variable air cushion at both ends to absorb high-speed end-of-stroke shock. The riveted SUS304 stainless steel barrel and aluminium covers resist mild corrosion and washdown environments, while the built-in piston magnet (-S) supports CMSG, DMSG and EMSG position switches. A rear CA pivot cover is fitted for direct clevis mounting.
For the same bore and stroke, the JIS-standard round-body design is noticeably shorter than a standard ISO 6432 cylinder, saving valuable machine space. Operating pressure ranges from 0.15 to 1.0 MPa, and the 1/8" port drives a 30 to 800 mm/s speed range. Based on the 0.5 MPa thrust, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCA Is Used
Light Package Diverting
Uses the 94 N safe working load to push small cartons off a high-speed belt, relying on the variable air cushion to stop the 300 mm stroke without slamming.
Small Component Ejection
Ejects lightweight machined parts from a lathe, where the needle-set cushion absorbs shock at rapid cycle rates to protect the finished surface.
Bin Lid Actuation
Opens and closes access hatches on equipment, using the CA pivot cover to manage the swing arc while the SUS304 barrel withstands humid shop conditions.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCA the Right Cylinder?
If 94 N of safe working load is insufficient, step up to the MFC25, which provides 245.3 N of push force at 0.5 MPa; there is no smaller MFC bore below 20 mm. The adjustable air cushion is essential for this 300 mm stroke when moving loads at high velocity, as it decelerates the piston smoothly without relying on a fixed bumper.
Because the cushion only slows the piston near the end of travel and acts as neither a lock nor a brake, the rod will drift if air pressure drops or the valve is centred. To suspend a load safely, fit an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion, and the included magnet enables solid-state or reed sensor feedback.
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 MFC20X300SCA FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod with an M8x1.25 male thread. 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.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. However, the variable air cushion only decelerates the piston near stroke end; it does not lock or hold position. If air loss occurs, the load will drift, so you must add an external rod lock or pilot check valve for vertical holding.
