Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 25mm 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 MFC20X25SCA
Dial in end-of-stroke deceleration with the AirTAC MFC20X25SCA, a JIS-standard round-body mini cylinder built for high-speed actuation. A variable air cushion at both ends uses a needle valve to absorb shock, protecting payloads far better than a fixed bumper. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore unit provides a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 margin. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors, while the CA rear pivot simplifies angular mounting. Equipped with a 1/8" port and an M8x1.25 male rod thread, its body is notably shorter than an equivalent ISO 6432 cylinder.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCA Is Used
Light-Part Ejection
Cushions the rapid ejection of small plastic or metal parts from a mould at high cycle rates, reducing noise and impact stress on the 8 kg payload class.
Package Diverting
Provides smooth, shock-free actuation for a lightweight sorting gate, using the CA pivot to swing packages gently onto an adjacent belt.
Small Tray Indexing
Pushes thin material trays precisely over a 25 mm stroke, relying on the -S magnet and DMSG sensor to confirm end-of-travel positioning.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCA the Right Cylinder?
For lighter payloads, no smaller MFC bore exists, but stepping up to the MFC25 increases the 0.5 MPa push force to 245.3 N if your 94 N safe working load proves insufficient. The variable air cushion is essential when cycling at high speeds or moving sensitive masses, as it decelerates the piston smoothly without harsh impacts. Remember that this cushion only eases the stop and does not lock the rod; if air pressure drops, the piston will drift. For suspended loads that must hold position, install an external rod lock or pilot-operated check valve.
The integrated CA back cover supports direct pivot mounting, and the built-in magnet (-S) enables seamless position sensing with CMSG, DMSG or EMSG switches. You can also adapt the unit using LB foot, FA flange, SDB pivot-block or TC trunnion accessories to suit your frame.
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 MFC20X25SCA FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod with an M8x1.25 male thread. 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 of 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end; it is not a brake or lock. If air pressure drops, the piston will drift. For vertical loads, you must use an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to monitor position.
