Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MFC20X100CM
Delivering 157 N of push force at 0.5 MPa, this double-acting mini cylinder is engineered for JIS-standard round-body applications where space is tight. The MFC20X100CM features a 20 mm bore, an 8 mm rod, and a 1/8" port, generating a theoretical maximum of 32 kgf at 1.0 MPa. Its riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown environments. For the same bore and stroke, the MFC body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
The defining feature is the variable air cushion at both ends, which uses a needle valve to soak up high-speed end-of-stroke shock, protecting the load and cutting noise. This specific configuration includes a CM round-end rear cover. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. Based on the 0.5 MPa push rating, the safe working load is roughly 94 N, lifting about 8 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100CM Is Used
Package Diverting
Pushes small cartons off a sorting line at high speed, relying on the adjustable air cushion to prevent harsh impacts that could damage lightweight packaging.
Small Part Ejection
Ejects machined components from a fixture, using the 157 N push force to clear the zone quickly while the needle-set cushion minimizes end-of-stroke noise.
Bin Gate Actuation
Opens and closes lightweight hopper gates for dry goods, where the SUS304 stainless barrel withstands mildly humid or dusty ambient conditions.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100CM the Right Cylinder?
When sizing this 20 mm bore actuator, step down if your load is very light, or move up to the MFC25 which provides 245.3 N of push force at 0.5 MPa for heavier demands. The adjustable cushion is essential if you are cycling near the 800 mm/s maximum speed or moving a sensitive payload, as it allows you to tune the deceleration precisely. Note that the cushion only slows the piston near the stroke end; it is not a brake. If the application requires the load to be held in place during air loss, you must fit an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets 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 MFC20X100CM FAQ
This 20 mm bore double-acting cylinder has a 1/8" port and an M8x1.25 male rod 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 force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It also features a CM round-end rear cover and a variable air cushion at both ends to decelerate loads, but this cushion acts only as a shock absorber and not as a locking brake.
