Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 500mm 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 MFC20X500U
Delivering 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles long 500 mm strokes with precision. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard.
A defining feature is the variable air cushion at both ends, which uses a needle valve to soak up end-of-stroke shock at high speeds, protecting your payload and cutting noise. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors. It carries a U flat-end rear cover and operates on a 1/8" port. 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 MFC20X500U Is Used
Long-Reach Transfer
Extends components across a 500 mm span using 157 N of push force, relying on the U flat-end cover for flush mounting against machine frames.
High-Speed Diverting
Pushes lightweight cartons at speed, letting the variable air cushions absorb the end-of-stroke impact to prevent product damage.
Vertical Lowering
Lowers an 8 kg payload smoothly, using the adjustable needle cushions to decelerate the descent before the end of the stroke.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500U the Right Cylinder?
When sizing this 20 mm bore, consider stepping up to the MFC25 if you need more thrust, as it provides 245.3 N at 0.5 MPa. Since 20 mm is the smallest available MFC bore, there is no smaller option in this series. The variable air cushion is essential if you are moving loads at high speeds over the full 500 mm stroke, as it decelerates the piston smoothly. Note that the cushion only slows the piston near the end of travel; it is not a brake. If you need to hold a load vertically during air loss, add an external rod lock or pilot check valve. Finally, because this SKU has no magnet, you must select an -S variant if your application requires position sensing.
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 MFC20X500U FAQ
This 20 mm bore cylinder features 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, this specific SKU does not include a magnet. You must purchase an -S variant to use CMSG, DMSG, or EMSG sensors. The variable air cushion and SUS304 stainless build are present, but position sensing is unavailable on this base model.
