Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X65SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X65SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 65mm 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 MFC32X65SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the U flat-end rear cover keeps the overall length down. Because it follows JIS round-body geometry, the body is physically shorter than an ISO 6432 cylinder for the same 65 mm stroke.
A built-in piston magnet (-S) allows direct mounting of CMSG, DMSG or EMSG switches for position sensing. Operating at speeds of 30-800 mm/s via a 1/4 inch port, it provides a safe working load of about 241 N. It will lift roughly 20.5 kg vertically with a 2:1 safety margin, though an external rod lock or pilot check valve is required to hold a load on air loss.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X65SU Is Used
Bottle Diverting
Pushes filled containers at high speed onto parallel packaging lanes, using the variable air cushion to prevent tipping or liquid splashing on impact.
Small Press Ejection
Ejects light metal stampings from a die, absorbing the sudden deceleration of the 402.2 N push stroke to protect the tooling and maintain cycle speed.
Carton Stopping
Halts corrugated boxes on a gravity roller conveyor; the needle-tuned cushion ensures the 32 mm rod stops cleanly without crushing the board.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X65SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MFC25 yields 245.3 N @0.5 MPa, whereas moving up to the MFC40 provides 628.3 N. Choose this model when driving heavier payloads at high cycle rates where the adjustable air cushion is essential to decelerate the rod without slamming. The cushion only decelerates near the stroke end and acts purely as a shock absorber, never as a braking lock.
Mounting flexibility is extensive, with options for LB foot, FA flange, SDB pivot and TC trunnion brackets. The -S magnet is already specified, so the cylinder is ready for CMSG, DMSG or EMSG sensors straight out of the box.
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 MFC32X65SU FAQ
This double-acting cylinder has a 32 mm bore, a 12 mm rod and a 1/4 inch 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. The theoretical maximum force is 82 kgf at 1.0 MPa. The male rod thread is M10x1.25.
No, the piston will drift if air is lost. The variable air cushion only decelerates the rod near the stroke end and is not a brake. To hold a suspended load, you must fit an external rod lock or a pilot-operated check valve. The SUS304 stainless build and -S magnet for CMSG/DMSG/EMSG switches make it highly durable and sensor-ready.
