Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CATC
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CATC is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MFC40X175CATC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy 175 mm strokes with precision. A variable air cushion at both ends lets you dial in the needle valve to absorb high-speed end-of-stroke shock, protecting your payload and cutting workshop noise. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, the JIS-standard MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped from the factory with a CA rear pivot cover and a TC trunnion mount, it is built for pivoting articulations. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. Based on the 0.5 MPa push rating, it yields a safe working load of roughly 377 N, meaning it can vertically lift about 32 kg with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CATC Is Used
Pallet Diverter
Articulates via the TC trunnion to push heavy pallets onto a secondary line, using the variable cushion to softly stop the 175 mm travel without jarring the load.
Case Erector Clamp
Provides the 628.3 N push force needed to hold cardboard cartons square during sealing, while the SUS304 barrel withstands occasional washdown.
Vertical Lift Gate
Lifts roughly 32 kg of gate weight vertically with a 2:1 safety margin, relying on the CA pivot cover to accommodate the shifting mechanical geometry.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CATC the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your load requires less than 402.2 N at 0.5 MPa, as no larger MFC bore exists above 40 mm. The adjustable air cushion is essential if you are moving heavy masses at high speeds up to 800 mm/s, preventing harsh impacts at the 175 mm stroke end. Remember that the cushion only decelerates the piston near the end of travel; it does not function as a brake or lock.
If your process requires the rod to hold its position during a compressed air loss or when the valve is centered, you must add an external rod lock or a pilot-operated check valve, as the piston will drift otherwise. This configuration features a 1/4 inch port and an M14x1.5 male rod thread. To integrate magnetic sensing, you would need to select the -S magnet variant instead of this non-magnet model.
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 MFC40X175CATC FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male rod thread. It delivers 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, its variable air cushion only decelerates the piston near the stroke end and does not lock the load.
