Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SU 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 MFC20X50SU
Dial in end-of-stroke deceleration with the AirTAC MFC20X50SU, a JIS-standard round-body mini cylinder built for high-speed actuation. The variable air cushion at both ends uses a needle valve to absorb shock, protecting your payload far better than a fixed bumper. Its SUS304 stainless barrel and riveted aluminium covers shrug off mild corrosion and washdown environments.
Generating 157 N of push and 131.9 N of pull at 0.5 MPa, this double-acting actuator is ideal for compact automation. It features a 1/8" port, an M8x1.25 male rod thread, and a built-in magnet for position sensing. The U flat-end rear cover and 50 mm stroke provide a neat footprint that is notably shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SU Is Used
Package Diverting
Uses the 157 N push force to rapidly deflect small parcels on a sorting line, relying on the adjustable air cushion to halt the 50 mm stroke smoothly without jarring the goods.
Small Part Ejection
Ejects lightweight moulded components at high speed, where the needle-set cushion absorbs end-of-stroke shock to protect delicate product finishes.
Bin Lid Actuation
Opens and closes access hatches in tight machinery cabinets, benefiting from the U flat-end rear cover and a body length that is shorter than an ISO 6432 cylinder.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50SU the Right Cylinder?
For lighter payloads, the MFC20X50SU provides a safe working load of roughly 94 N (about 60% of its 157 N push force at 0.5 MPa), lifting approximately 8 kg vertically with a 2:1 margin. If your application demands more thrust, step up to the MFC25 bore, which delivers 245.3 N at 0.5 MPa. Tune the variable air cushion precisely when running heavy loads or operating near the 800 mm/s maximum speed to minimize impact noise.
Because the -S suffix includes a piston magnet, this unit is ready for CMSG, DMSG, or EMSG switches. Note that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot-operated check valve.
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 MFC20X50SU 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 force of 32 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG sensors. However, the variable air cushion only decelerates the piston near stroke end; it is not a brake. For vertical load holding on air loss, you must use an external rod lock or pilot check valve.
