Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 400mm 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 MFC20X400SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless steel mini cylinder integrates a variable air cushion at both ends to absorb high-speed shocks. The 20 mm bore uses an 8 mm rod with an M8x1.25 male thread and a 1/8" port. Because the riveted SUS304 barrel and aluminium covers follow JIS standards, the overall body is noticeably shorter than an ISO 6432 cylinder for the same 400 mm stroke, saving valuable mounting length while resisting mild corrosion and washdown environments.
Equipped with a built-in magnet (-S) for CMSG, DMSG or EMSG switches, and a CA rear pivot cover, it handles speeds of 30-800 mm/s. The adjustable needle decelerates the piston near stroke end to protect machinery, but it is not a brake. Based on the 0.5 MPa thrust, the safe working load is about 94 N, meaning it lifts roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400SCA Is Used
Light Package Diverting
Uses the 157 N push force at 0.5 MPa to push small cartons off a high-speed belt, relying on the variable air cushion to stop the 400 mm travel without slamming.
Small Component Transfer
Moves delicate electronics across a 400 mm span where the adjustable needle deceleration prevents crushing parts that weigh under the 8 kg vertical lift limit.
Bin Lid Actuation
Opens and closes access hatches in washdown zones, benefiting from the SUS304 stainless barrel and riveted aluminium construction for mild corrosion resistance.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400SCA the Right Cylinder?
For lighter payloads, the MFC20 at 157 N push (@0.5 MPa) is suitable, whereas stepping up to the MFC25 provides 245.3 N if your fixture exceeds the 94 N safe working load. The variable air cushion is essential when cycling this 400 mm stroke at high speeds, as it prevents harsh end-of-stroke impacts that a fixed bumper cannot absorb. Note that this cylinder does not hold position on air loss; the piston will drift if pressure drops, so fit an external rod lock or pilot check valve for suspended loads. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, while the -S magnet enables solid-state or reed sensor tracking.
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 MFC20X400SCA 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 of 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a lock or brake, so the piston will drift on air loss. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches.
