Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 72mm 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 MFC20X72CA
Designed to absorb high-velocity impacts, the AirTAC MFC20X72CA relies on a needle-set variable air cushion at both ends to decelerate the piston smoothly, outperforming a standard bumper mini cylinder. This JIS-standard round-body unit features a SUS304 stainless barrel and riveted aluminium covers, offering mild corrosion resistance while remaining shorter than an ISO 6432 cylinder for the same 20mm bore and 72mm stroke.
Operating double-acting on a 1/8" port, it delivers a push force of 157 N at 0.5 MPa. In practical terms, this translates to a safe working load of roughly 94 N, or the ability to lift about 8 kg vertically with a 2:1 safety margin. The rear CA pivot cover simplifies angular mounting, though note this specific SKU lacks a magnet and therefore cannot support CMSG, DMSG or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72CA Is Used
Light-Part Ejection
Shoots small plastic mouldings off a tool at speed; the adjustable air cushion decelerates the 8 kg load to prevent cover damage without slowing cycle time.
Package Diverting
Pushes lightweight cartons onto a side belt; the CA pivot rear cover accommodates the slight angular misalignment of the diverting arm.
Small Component Sorting
Strokes 72mm rapidly to gate electronic parts into bins, using the needle valve to stop the rod abruptly but quietly for precise placement.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72CA the Right Cylinder?
When sizing this 20mm bore, step up to the MFC25X72CA if you need more thrust, as it provides 245.3 N at 0.5 MPa; there is no smaller MFC option, making this the baseline for light-duty cycles. The variable air cushion is essential when cycling at high speeds or moving sensitive loads, as it lets you dial in the exact deceleration to prevent end-of-stroke banging.
Because this is a plain double-acting cylinder, it will drift and cannot hold a load if air pressure drops or the valve is centred—the cushion only decelerates near the stroke end and acts purely as a shock absorber, never a brake. For suspended or gravity-loaded applications, install an external rod lock or a pilot-operated check valve. Furthermore, since this configuration ships without the -S magnet, position sensing is not supported.
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 MFC20X72CA FAQ
This 20mm bore cylinder features a 1/8" port and an 8mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 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 it cannot accept CMSG, DMSG or EMSG switches; you would need the -S variant for sensing. The SUS304 stainless build provides washdown resistance, and the variable air cushion only decelerates the piston near stroke end—it does not lock or hold the load.
