Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100U 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 MFC20X100U
Tuned for rapid cycles, the MFC20X100U relies on a variable air cushion at both ends to absorb high-speed end-of-stroke shock, protecting payloads and cutting noise better than a fixed bumper. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, resisting mild corrosion and washdown. For the same bore and stroke, its body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
Operating as a double-acting actuator with a 100 mm stroke and 1/8" port, this bore generates 157 N of push force at 0.5 MPa. That yields a safe working load of roughly 94 N, or enough to lift about 8 kg vertically with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors; choose an -S variant if position feedback is required. The flat-end U back cover suits direct rear mounting.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100U Is Used
Light Part Ejection
Uses the 94 N safe working load to push small plastic mouldings out of a fixture rapidly, relying on the needle-set cushion to prevent impact bounce.
Package Diverting
Swings a lightweight guide arm to sort small cartons on a line, where the shorter-than-ISO-6432 body preserves tight transfer clearances.
Component Pressing
Snaps small clips or pins into housings at speed, letting the adjustable air cushion absorb the sudden end-of-stroke shock to protect the assembly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X100U 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 MFC bore, there is no smaller option. The variable air cushion is essential when driving heavier masses at high speeds, as it decelerates the piston near the stroke ends. Remember this cushion is not a brake: the piston will drift on air loss, so fit an external rod lock or pilot check valve to hold suspended loads. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion blocks.
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 MFC20X100U 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, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches will not function. You must select an MFC20 model with the -S suffix for position sensing. The SUS304 stainless barrel and riveted aluminium covers provide excellent mild corrosion resistance.
