Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CA 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 MFC40X175CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder tackles heavy loads with precision. The MFC40X175CA features a variable air cushion at both ends, allowing you to dial in a needle valve to smoothly decelerate the 175 mm stroke, eliminating end-of-travel bangs. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, and the entire JIS-standard body is notably shorter than a comparable ISO 6432 cylinder.
Equipped with a CA rear pivot cover, it is built for articulated rod-end mounting. The 40 mm bore uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. For vertical lifting, it handles roughly 32 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept position switches; you would need the -S variant for CMSG or DMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CA Is Used
Heavy Clamping Press
Uses the 879.6 N push force at 0.7 MPa to secure thick metal plates, while the needle-tuned cushion prevents jarring impacts at the end of the 175 mm travel.
Pallet Diverter Arm
Swings via the CA pivot mount to redirect heavy pallets on a high-speed line, relying on the variable air cushion to absorb the sudden directional changes.
Vertical Carton Flap Folder
Folds thick cardboard flaps downward, lifting about 32 kg safely with a 2:1 margin, with the SUS304 barrel surviving humid or washdown packaging environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CA the Right Cylinder?
If 628.3 N at 0.5 MPa feels excessive, stepping down to the MFC32 provides 402.2 N, but since 40 mm is the largest available MFC bore, you cannot size up within this family. The adjustable air cushion is essential when driving heavy masses at high speeds, as it prevents destructive impact without adding external shock absorbers. The cylinder operates between 30 and 800 mm/s.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If your application must hold a vertical load during a pressure drop, install an external rod lock or pilot check valve. Furthermore, without the -S magnet option, this non-sensing model cannot support CMSG, DMSG, or EMSG switches.
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 MFC40X175CA FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod. It generates 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 a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must specify the -S option for sensing capabilities. The adjustable air cushion at both ends only serves to decelerate the load near stroke end and will not hold position on air loss.
