Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 70mm 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 MFC20X70SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. A two-way oil-retaining piston seal and a fixed anti-impact pad on the front cover further smooth operation. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown environments.
Thanks to its JIS-standard round-body architecture, the unit is notably shorter than an ISO 6432 cylinder for the same 70 mm stroke, saving valuable mounting length. The integrated -S piston magnet supports CMSG, DMSG and EMSG switches for position sensing, while the CA rear pivot cover simplifies direct rear articulation. Operating pressure spans 0.15 to 1.0 MPa, with a 1/8" air port and an M8x1.25 male rod thread.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70SCA Is Used
Small Parts Ejection
Shoots lightweight plastic components out of a machining centre at speed, relying on the adjustable air cushion to prevent end-of-stroke impact damage.
Package Diverting
Pushes small cartons off a high-throughput belt, using the 157 N thrust to overcome friction while the CA pivot accommodates slight misalignment.
Flap Folding
Folds cardboard flaps on compact boxes where space is tight, taking advantage of the shorter JIS body length compared to ISO 6432 alternatives.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X70SCA the Right Cylinder?
For lighter payloads, this 20 mm bore offering provides a safe working load of roughly 94 N (about 60% of its 157 N push force at 0.5 MPa) and lifts approximately 8 kg vertically with a 2:1 margin. If your application demands more thrust, stepping up to the MFC25 yields 245.3 N at 0.5 MPa. The variable air cushion is essential when cycling at high speeds or moving heavy loads, as it decelerates the piston near stroke end to protect the mechanism.
Remember that the cushion only decelerates and does not function as a lock or brake; the piston will drift if air pressure drops or the valve is centred. To suspend a load securely, install an external rod lock or a pilot-operated check valve. Mounting is flexible via the CA back cover, and the -S magnet enables direct sensor integration.
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 MFC20X70SCA FAQ
This 20 mm bore cylinder features a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it provides 157 N push and 131.9 N pull force. 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, the variable air cushion only decelerates the piston near the stroke end and is not a brake. The piston will drift on air loss. For vertical load holding, you need an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to confirm position.
