Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X35U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X35U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 35mm 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 MFC20X35U
Soaking up end-of-stroke shock at high speeds, this double-acting JIS-standard round-body mini cylinder features a needle-set variable air cushion at both ends. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the flat-end U back cover provides a flush rear mounting face. For the same 20 mm bore and 35 mm stroke, the riveted rolling-packed construction is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space.
Generating 157 N of push force and 131.9 N of pull force at 0.5 MPa, this 1/8" ported unit suits compact actuation tasks. Based on the 0.5 MPa push rating, it handles a safe working load of about 94 N, or lifts roughly 8 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X35U Is Used
Package Diverter
Snaps a lightweight routing gate at 30-800 mm/s, relying on the adjustable air cushion to halt the 8 kg vertical load smoothly without slamming the flat-end U cover.
Small-Part Press
Applies up to 157 N of push force at 0.5 MPa to seat bearings, with the needle valve tuned to decelerate the 8 mm rod gently at the end of the 35 mm stroke.
Bin Gate Actuator
Opens and closes a compact hopper flap where the SUS304 stainless barrel withstands mildly humid ambient conditions and the short JIS body fits tight clearances.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X35U the Right Cylinder?
If 94 N of safe working load is insufficient, step up to the MFC25, which raises the push force to 245.3 N at 0.5 MPa; as the 20 mm bore is the smallest available in this series, there is no smaller MFC option. Choose this adjustable-cushion model over a fixed-bumper MF variant when driving heavier masses at high velocities, as the needle valve lets you dial in deceleration to protect the load. Remember that the air cushion only slows the piston near stroke end—it is not a brake; if you need to prevent drift on air loss, fit an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, but because this SKU lacks the -S suffix, magnetic sensing is unsupported.
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 MFC20X35U FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod with an M8x1.25 male 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.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The variable air cushion at both ends is adjustable via a needle valve to reduce shock, but it only decelerates the piston and does not lock or hold the load in place.
