Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X425SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X425SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 425mm 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 MFC20X425SCA
Saving mounting length compared to an equivalent ISO 6432 unit, this JIS-standard round-body mini cylinder integrates a CA rear pivot for angular motion. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the double-acting piston achieves a 157 N push at 0.5 MPa. It carries an -S magnet for position sensing.
A defining feature is the variable air cushion at both ends; turning the needle lets you soak up high-speed end-of-stroke shock to protect the load and cut noise. With a safe working load around 94 N, it lifts about 8 kg vertically with a 2:1 margin. The 1/8" port and 425 mm stroke deliver rapid 30-800 mm/s cycling without fixed bumpers.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X425SCA Is Used
Angular Component Pusher
Uses the CA pivot to accommodate misalignment while pushing 8 kg assemblies at speed, relying on the needle-set air cushion to prevent end-of-stroke impact.
High-Speed Diverter Arm
Cycles rapidly across the 425 mm stroke to deflect light goods on a washdown line; the SUS304 barrel handles damp conditions without corroding.
Pneumatic Sorting Gate
Switches sorting lanes for parcels under 94 N, using the CMSG sensor to confirm gate position and the variable cushion to silence repetitive shocks.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X425SCA the Right Cylinder?
If 157 N push at 0.5 MPa is insufficient, step up to the MFC25, which provides 245.3 N; since 20 mm is the smallest bore in the MFC family, there is no smaller option. The adjustable air cushion is essential when driving heavy loads at high speeds, as it decelerates the piston near the stroke ends to reduce impact. Note that the cushion only decelerates and does not lock the piston; if air pressure drops, the cylinder drifts, so fit an external rod lock or pilot check valve to hold a load. Mounting uses the CA rear pivot, and the built-in -S magnet supports CMSG, DMSG, or 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 MFC20X425SCA FAQ
This double-acting cylinder has a 20 mm bore and a 1/8" port. It generates a push of 157 N and a pull of 131.9 N at 0.5 MPa, increasing to a push of 219.8 N and a pull of 184.7 N at 0.7 MPa. 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 acts as neither a lock nor a brake. On air loss, the piston drifts, so you must install an external rod lock or pilot check valve to hold a suspended load. The -S magnet allows CMSG, DMSG, or EMSG switches to track position.
