Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCM 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 MFC40X15SCM
Delivering 628.3 N of push force at 0.5 MPa, this JIS-standard round-body mini cylinder brings variable air cushioning to heavy-duty automation. Tuning the cushion needle at both ends soaks up high-speed end-of-stroke shock, protecting your payload far better than a fixed bumper. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the compact riveted body is notably shorter than an ISO 6432 cylinder for the same 40 mm bore and 15 mm stroke.
Driven by a 1/4" port and a 16 mm rod with an M14x1.5 male thread, it moves at 30-800 mm/s. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches, and the CM round-end rear cover supports straightforward mounting. With a 0.5 MPa push force, you get a safe working load around 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCM Is Used
Short-Stroke Stamping
Uses the 15 mm stroke to deliver 628.3 N of rapid push force for pressing small bearings or rivets, relying on the needle-tuned air cushion to prevent harsh end impacts.
Heavy Divertor Gate
Snaps a high-inertia diverting flap into place on a packaging line, where the variable cushion absorbs the sudden shock of stopping the heavy mechanism.
Pallet Stopper Block
Halts incoming pallets on a roller conveyor; the 40 mm bore provides the necessary stopping power while the cushion shields the load from abrupt deceleration.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCM the Right Cylinder?
For lighter cycles requiring less than 400 N of push, step down to the MFC32 (402.2 N at 0.5 MPa); since 40 mm is the largest available MFC bore, you cannot size up within this family. The variable air cushion is essential when driving heavy loads at high speeds, as it decelerates the piston smoothly right before the end cap. Remember that this cushion only reduces impact velocity—it is not a brake. If your setup must hold a vertical load during air loss or when a valve is centred, the piston will drift, so fit an external rod lock or pilot-operated check valve. Combine the CM back cover with your chosen mounting hardware and use the built-in -S magnet for precise position sensing.
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 MFC40X15SCM FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port and a 16 mm rod with an M14x1.5 thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the air cushion only decelerates the piston near the stroke end and does not function as a lock or brake; you need an external rod lock or pilot check valve to hold a load on air loss. The -S suffix indicates a built-in piston magnet allowing you to mount CMSG, DMSG or EMSG sensors for position detection.
