Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 40mm 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 MFC20X40SCM
Generating 157 N of push force at 0.5 MPa, this double-acting mini cylinder features a needle-adjustable variable air cushion at both ends to absorb high-speed end-of-stroke shock. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown environments, while the built-in piston magnet enables position sensing. Equipped with a 1/8" port and an M8x1.25 male rod thread, it operates at speeds from 30 to 800 mm/s.
For the same bore and stroke, the JIS-standard round-body design is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. The CM round-end back cover rounds out the configuration.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCM Is Used
Light Part Ejection
Uses the 157 N push force to eject small molded parts rapidly, with the variable cushion preventing bounce-back at the end of the stroke.
Package Diverting
Diverts lightweight cartons on a conveyor at high speed; the adjustable needle absorbs the shock of the stop impact to protect the packaging.
Vertical Lift Gates
Raises and lowers small access gates, safely lifting an 8 kg load vertically while the cushion softens the descent at the bottom.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCM the Right Cylinder?
If 157 N at 0.5 MPa is insufficient, step up to the MFC25, which provides 245.3 N; since 20 mm is the smallest available MFC bore, there is no smaller option. The variable air cushion is essential when driving heavier loads at high speeds, as it decelerates the piston smoothly. Note that this cylinder cannot hold a load on air loss—the piston will drift—so add an external rod lock or pilot check valve for suspended loads. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and the -S magnet allows use of 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 MFC20X40SCM FAQ
This 20 mm bore cylinder has a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. 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.
The variable air cushion at both ends uses a needle valve to decelerate the piston near the stroke end, reducing shock at high speeds. It is not a brake and does not hold position on air loss; the piston will drift. For suspended loads, install an external rod lock or pilot check valve.
