Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MFC40X15CM
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore JIS-standard round-body mini cylinder handles heavy quick-stroke tasks. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
A variable air cushion at both ends lets you turn a needle to soak up high-speed shock, protecting the load and cutting noise versus a simple bumper. Based on the 0.5 MPa push rating, it handles a safe working load of about 377 N, lifting roughly 32 kg vertically with a 2:1 margin. This specific SKU lacks the -S magnet, so it cannot take CMSG, DMSG or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CM Is Used
Heavy-Duty Clamping
Uses the full 628.3 N push force at 0.5 MPa to secure dense metal parts for machining, with the air cushion absorbing the abrupt stop of the 15 mm stroke.
Box Sealing Press
Drives a short sealing jaw rapidly while the needle-adjusted cushion prevents crushing the carton at the stroke end.
Pallet Stopper
Halts heavy pallets on a line; the SUS304 body withstands washdown while the cushion softens the repeated high-speed impacts.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CM the Right Cylinder?
If 402.2 N from the MFC32 is too light, this 40 mm bore is the top option. There is no larger MFC frame, so loads beyond the 879.6 N push at 0.7 MPa require a different series. The 15 mm stroke is ideal for fast clamping, where tuning the variable air cushion prevents harsh end-of-stroke impacts.
This non-magnetic SKU cannot host position switches. The 1/4" port matches the 16 mm rod with its M14x1.5 male thread. Because a standard cylinder drifts on air loss, add an external rod lock or pilot check valve to hold suspended loads safely.
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 MFC40X15CM FAQ
It has a 40 mm bore, 15 mm stroke, 1/4" port, and a 16 mm rod with an M14x1.5 male thread. The double-acting thrust is 628.3 N push and 527.8 N pull at 0.5 MPa, or 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 SKU does not include the -S magnet, so it cannot host CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. The variable air cushion at both ends only decelerates the piston near stroke end; it is not a lock or brake.
