Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SU 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 MFC32X550SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built for demanding actuation. The 550 mm stroke exceeds the 500 mm standard limit, making this specific SKU a made-to-order item. A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock, protecting your payload during high-speed cycles. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown environments.
For the same bore and stroke, the JIS-standard round-body design is shorter than a comparable ISO 6432 cylinder, saving valuable mounting length. Because the -S suffix equips the piston with a magnet, this model supports CMSG, DMSG, and EMSG position switches. Factoring a 2:1 safety margin, it lifts about 20.5 kg vertically, with a safe working load near 241 N. It features a 1/4" port and a U flat-end rear cover.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SU Is Used
Long-Stroke Diverting
Pushes packages across a wide conveyor belt using the 550 mm stroke, relying on the tuned air cushion to stop the 402.2 N thrust without slamming.
Vertical Lift Gate
Raises a 20 kg access panel with a 2:1 safety margin, using the U flat-end rear cover for secure top mounting and the cushion to prevent bounce.
Carton Forming Press
Actuates a folding mechanism at high speed where the SUS304 stainless barrel withstands occasional washdowns during facility cleaning.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X550SU the Right Cylinder?
When sizing this 32 mm bore, check both directions: the MFC25 provides 245.3 N at 0.5 MPa if your load is lighter, while the MFC40 offers 628.3 N for heavier demands. The adjustable air cushion is essential when running at high speeds or moving substantial mass, as it decelerates the piston smoothly. Note that the cushion only slows the piston near stroke end; it does not lock or hold the load. If air pressure drops, the piston will drift. To maintain position, add an external rod lock or a pilot-operated check valve. The built-in magnet (-S) pairs directly with CMSG, DMSG, or EMSG sensors, and you can mount it via LB foot, FA flange, SDB pivot, or TC trunnion.
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 MFC32X550SU 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, or 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The male rod thread is M10x1.25. Note the 550 mm stroke is non-standard and made-to-order.
No, the variable air cushion only decelerates the piston near the end of the stroke; it is not a brake or lock. If air is lost, the piston will drift. To hold a load, use an external rod lock or pilot check valve. The -S magnet allows CMSG, DMSG, and EMSG sensors to confirm position.
