Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SUTC
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SUTC is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 50mm 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 MFC20X50SUTC
Dial in end-of-stroke deceleration with the AirTAC MFC20X50SUTC, a 20mm bore, 50mm stroke mini cylinder featuring a needle-set variable air cushion at both ends. It generates 157N of push force at 0.5MPa, making it a solid fit for compact, high-speed actuation.
The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown. A built-in magnet (-S) supports CMSG, DMSG, or EMSG sensors, while the flat U back cover and TC trunnion mount simplify pivot installations. For the same bore and stroke, this JIS-standard round body is shorter than an ISO 6432 cylinder. It uses a 1/8" port and an M8x1.25 male rod thread.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SUTC Is Used
Light Package Diverting
Handles small cardboard cartons on a sorting line using the 94N safe working load, relying on the variable air cushion to silently stop the 50mm stroke at high cycle rates.
Component Ejection
Pushes lightweight machined parts out of a fixture; the SUS304 barrel withstands occasional cutting fluid splash while the TC trunnion accommodates slight misalignment.
Bin Lid Actuation
Opens and closes small access hatches vertically, lifting under 8kg safely with a 2:1 margin, while the U flat-end cover prevents rear interference in tight enclosures.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SUTC the Right Cylinder?
At 0.5MPa this 20mm bore yields 157N push and 131.9N pull, offering a safe working load of about 94N (roughly 60% of the rated push) or a 2:1 vertical lift capacity near 8kg. If your payload drops below that, there is no smaller MFC bore; if you need more force, step up to the MFC25, which provides 245.3N at 0.5MPa. The adjustable air cushion is essential when cycling at high speeds to prevent impact damage.
Remember that the cushion only decelerates the piston near the stroke end—it does not function as a brake. If the air supply drops, the piston will drift; use an external rod lock or pilot check valve to hold a suspended load. The included -S magnet enables position sensing, and the TC trunnion pairs with the U back cover for articulated mounting.
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 MFC20X50SUTC FAQ
This 20mm bore double-acting cylinder uses a 1/8" port. At 0.5MPa it provides 157N push and 131.9N pull. At 0.7MPa it provides 219.8N push and 184.7N pull. The theoretical maximum force is 32kgf at 1.0MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and acts purely as a shock absorber, not a brake. On air loss the piston will drift. To hold a suspended load, you must install an external rod lock or a pilot-operated check valve.
