Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X420SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X420SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 420mm 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 MFC20X420SCM
Generating 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder features a needle-adjustable variable air cushion at both ends to absorb high-speed end-of-stroke shock. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the JIS-standard round-body construction is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.
Equipped with a built-in piston magnet (-S) for CMSG, DMSG or EMSG switches, a CM round-end rear cover, and a 420 mm stroke, it handles rapid cycling with ease. Based on the 0.5 MPa push rating, it provides a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 safety margin. The 1/8 inch air port and M8x1.25 male rod thread ensure straightforward integration.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X420SCM Is Used
Package Diverting
Pushes light parcels at high speed on a sorting line, relying on the adjustable air cushion to silently stop the 420 mm stroke without slamming.
Small Component Ejection
Ejects machined plastic parts from a mould cavity, using the 157 N push force while the needle-set cushion protects delicate product edges.
Bin Tapping
Taps small component bins to prevent bridging, where the compact JIS body length fits tight framework and the stainless barrel resists dust.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X420SCM the Right Cylinder?
When sizing this 20 mm bore actuator, step down if payload is light or step up to the MFC25, which delivers 245.3 N of push force at 0.5 MPa for heavier demands. 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 load. Remember that the cushion only decelerates near the stroke end; it is not a brake, so an external rod lock or pilot check valve is required to hold a load securely on air loss.
Mounting flexibility is provided via LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing out of the box.
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 MFC20X420SCM FAQ
This 20 mm bore cylinder features a 1/8 inch air 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.
No, the variable air cushion only decelerates the piston near the stroke end and does not act as a lock or brake. The piston will drift on air loss or valve centring, so you must fit an external rod lock or pilot-operated check valve for suspended loads.
