Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MFC32X40CM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MFC32X40CM is a JIS-standard round-body mini cylinder built for double-acting operation. A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock at high speeds, protecting your payload and cutting noise. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the CM round-end rear cover keeps the footprint tight. For the same 32 mm bore and 40 mm stroke, this body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
At 0.5 MPa it pulls 345.6 N and reaches a theoretical maximum of 82 kgf at 1.0 MPa. Based on the 0.5 MPa push figure, this bore yields a safe working load of roughly 241 N, meaning it can lift about 20.5 kg vertically with a 2:1 safety margin. The piston rod is 12 mm with an M10x1.25 male thread, and the air port is 1/4". Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40CM Is Used
Light Press Assembly
Drives small bearing inserts with 402.2 N of thrust, using the adjustable air cushion to prevent impact damage when bottoming out the 40 mm stroke.
Package Diverting
Pushes cartons at high cycle rates; the needle-set cushion absorbs the end-of-stroke shock to keep the 32 mm bore actuator quiet and stable.
Vertical Lift Gates
Lifts roughly 20.5 kg flaps with a 2:1 safety margin at 0.5 MPa, relying on the SUS304 barrel for humid warehouse environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40CM the Right Cylinder?
If 241 N of safe working load is too much, step down to the MFC25 which provides 245.3 N at 0.5 MPa; if your payload requires more thrust, the MFC40 pushes 628.3 N at 0.5 MPa. The adjustable air cushion is essential when cycling heavy loads at high speeds, as it decelerates the piston smoothly near the stroke end. Remember that this cushion only slows the piston and is not a brake. Because a standard cylinder does not hold position on air loss, you must add an external rod lock or pilot-operated check valve for suspended loads. Furthermore, since this configuration has no -S magnet, position sensing is unavailable without switching to a magnet-equipped variant.
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 MFC32X40CM FAQ
This 32 mm bore double-acting cylinder features a 1/4" port and an M10x1.25 male rod thread. It pushes 402.2 N and pulls 345.6 N at 0.5 MPa. At 0.7 MPa the push is 563 N and pull is 483.8 N, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the magnet-equipped variant for sensing. The variable air cushion at both ends only decelerates the piston near stroke end and does not lock or hold the load.
