Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 250mm 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 MFC20X250SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a needle-adjustable variable air cushion at both ends to absorb high-speed end-of-stroke shock. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the built-in -S piston magnet enables CMSG, DMSG or EMSG sensor switches for position feedback.
Equipped with a CA rear pivot cover and a 250 mm stroke, the MFC20X250SCA runs at 30-800 mm/s on a 1/8" port. It provides a safe working load of roughly 94 N (about 60% of its 0.5 MPa push rating) and lifts approximately 8 kg vertically with a 2:1 safety margin. For the same bore and stroke, its body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCA Is Used
Light-Duty Pick & Place
Ideal for high-speed component transfer where the variable air cushion smoothly stops the 250 mm stroke, protecting delicate electronics from end-of-stroke impact.
Package Diverting
Provides reliable 157 N push at 0.5 MPa to deflect small cartons on a line, with the SUS304 barrel resisting dust and occasional washdown in packing zones.
Small Part Ejection
Ejects moulded parts quickly; the needle-set cushion absorbs the shock of the rapid return, reducing noise and wear on the riveted aluminium covers.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCA the Right Cylinder?
When sizing this 20 mm bore unit, step down if loads are light or up to the MFC25 (245.3 N push at 0.5 MPa) if you need greater thrust. The variable air cushion is essential when cycling at high speeds or moving sensitive masses, as it lets you dial in the exact deceleration to protect the workpiece. Remember the cushion only decelerates near the stroke end; it is not a brake. If the application must hold a load during air loss or valve centring, the piston will drift, so fit an external rod lock or pilot-operated check valve. Mounting is handled via the CA pivot cover, and the included -S magnet supports CMSG, DMSG and EMSG switches.
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 MFC20X250SCA FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. 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.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. The variable air cushion only decelerates the piston near stroke end; it does not lock or hold position on air loss, so a vertical load will drift unless you add an external rod lock or pilot check valve.
