Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MFC32X400SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder tackles heavy loads with a 400 mm stroke. The defining feature of the MFC series is the variable air cushion at both ends; by turning a needle valve you tune the end-of-stroke deceleration to absorb shock at high speeds, a major upgrade over fixed bumper designs. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, this JIS-standard round-body cylinder is notably shorter than an ISO 6432 unit, saving valuable mounting length. It includes a CA rear pivot cover and a built-in piston magnet (-S) for direct mounting of CMSG, DMSG or EMSG sensors. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread ensure solid pneumatic and mechanical connections.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCA Is Used
High-Speed Diverters
Uses the 402.2 N thrust to push packages on a 400 mm stroke, while the needle-tuned air cushion silently halts the 32 mm piston at high cycle rates without jarring the belt.
Articulated Tooling Arms
The CA rear pivot accommodates swinging linkages, and the SUS304 body handles light splashing while the cylinder lifts roughly 20.5 kg tooling heads vertically.
Vertical Material Gates
Raises and lowers access gates on automated storage lines; the adjustable cushion absorbs the kinetic energy of the falling load at the bottom of the stroke.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCA the Right Cylinder?
When sizing this 32 mm bore, check both directions: the smaller MFC25 provides 245.3 N @0.5 MPa, while the larger MFC40 offers 628.3 N @0.5 MPa. The variable air cushion is essential if you are moving heavy payloads at high cycling speeds, as it prevents harsh end-of-stroke impacts. Remember that the cushion only decelerates the piston near the end of travel; it does not function as a brake. If your application must hold a vertical load during air loss or when a valve is centered, you must add an external rod lock or a pilot-operated check valve, because the piston will drift. The CA pivot mount is ideal for articulating linkages.
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 MFC32X400SCA FAQ
This 32 mm bore double-acting cylinder has a 1/4" port and a 12 mm rod. 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. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of its stroke to reduce shock; it is not a brake or lock. The piston will drift on air loss. For load holding, install an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to track position.
