Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 550mm stroke, 1/4" 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 MFC32X550SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder tackles heavy loads with precision. The MFC32X550SCA features a needle-adjustable variable air cushion at both ends, allowing you to dial in end-of-stroke deceleration to absorb shock at high cycling speeds. Its JIS-standard round-body construction pairs a SUS304 stainless steel barrel with riveted aluminium covers for excellent mild corrosion and washdown resistance. Because this 550 mm unit exceeds the 500 mm standard stroke maximum, it is supplied as a non-standard, made-to-order item.
The integrated -S piston magnet supports CMSG, DMSG and EMSG reed or electronic switches for position sensing, while the CA rear pivot cover simplifies rear-clevis mounting. For the same bore and stroke, the riveted MF body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space without sacrificing the 1/4" port flow. Derived from the 0.5 MPa push rating, the safe working load is approximately 241 N, yielding a vertical lift capacity of about 20.5 kg with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SCA Is Used
High-Speed Diverters
Leveraging the 402.2 N push force to rapidly actuate routing gates on packaging lines, with the variable cushion absorbing the shock of sudden direction changes at 800 mm/s.
Controlled Lowering
Managing vertical loads up to 20.5 kg, where the needle-adjusted air cushion prevents hard bottoming out when lowering heavy product chutes over the 550 mm travel.
Washdown Actuators
Operating reliably in food-grade environments thanks to the SUS304 stainless barrel, driving tooling arms that require the rear CA pivot mounting for articulated movement.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SCA the Right Cylinder?
When sizing this 32 mm bore unit, evaluate your force needs against adjacent bores: the MFC25 provides 245.3 N at 0.5 MPa if your load is lighter, while the MFC40 steps up to 628.3 N for heavier demands. The variable air cushion is essential for this model if you are moving substantial masses at high speeds, as it prevents harsh end-of-stroke impacts that a fixed bumper cannot absorb. Keep in mind the cushion only decelerates the piston near the stroke end; it does not function as a brake. If the application requires the load to be held in place during air loss or valve centering, you must add an external rod lock or pilot-operated check valve, as the piston will drift. Ensure you specify the CA pivot cover and confirm the -S magnet option when ordering CMSG or DMSG sensors.
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 MFC32X550SCA FAQ
This double-acting cylinder has a 32 mm bore, a 12 mm rod, and a 1/4" port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The 550 mm stroke is non-standard, and the unit operates at speeds between 30 and 800 mm/s.
No, the variable air cushion only decelerates the piston near the end of the stroke to reduce shock; it is not a locking mechanism. The piston will drift if air pressure is lost or the valve is centered. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
