Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100SU 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 MFC20X100SU
Tuned by a needle valve at both ends, the variable air cushion on this double-acting mini cylinder absorbs high-speed end-of-stroke shock to protect your payload. The AirTAC MFC20X100SU features a JIS-standard round-body design with a SUS304 stainless barrel and riveted aluminium covers, offering mild corrosion and washdown resistance. For the same 20 mm bore and 100 mm stroke, the riveted rolling-packed construction is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
Operating at 30-800 mm/s on a 1/8" port with an 8 mm rod, it pushes 157 N and pulls 131.9 N at 0.5 MPa. This yields a safe working load of roughly 94 N, meaning it lifts about 8 kg vertically with a 2:1 safety margin. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches, while the U flat-end back cover supports direct rear mounting.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100SU Is Used
Light Part Ejection
Cushions the 100 mm stroke when ejecting 8 kg plastic parts at high speed, preventing impact damage at the end of travel.
Package Diverting
Provides 157 N of push at 0.5 MPa to deflect small cartons on a line, with the adjustable cushion ensuring smooth stops.
Compact Vertical Lift
Fits into tight machine frames thanks to its shorter-than-ISO-6432 body, safely lifting 8 kg loads on the 1/8" ported cylinder.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100SU the Right Cylinder?
If 157 N of 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 to drop down to. Dial in the variable air cushion when cycling at high speeds or moving sensitive masses, as the needle setting decelerates the piston near the stroke end without acting as a lock. Because a standard cylinder drifts and cannot hold a load on air loss, install an external rod lock or pilot-operated check valve for suspended loads. Mounting is versatile via the U flat-end back cover, and the built-in -S magnet is ready for CMSG, DMSG or EMSG sensors.
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 MFC20X100SU FAQ
This 20 mm bore, 100 mm stroke cylinder has 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 piston will drift on air loss. The variable air cushion only decelerates the piston near the stroke end and is not a brake or lock. For suspended loads, use an external rod lock or pilot check valve. The -S magnet allows CMSG, DMSG or EMSG sensors for position feedback.
