Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCA 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 MFC40X15SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy fast cycles with ease. The integrated variable air cushion at both ends lets you dial in a needle valve to absorb end-of-stroke shock, protecting your payload and cutting workshop noise. A built-in piston magnet enables position sensing with CMSG, DMSG or EMSG switches.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the JIS-standard round-body design resists mild corrosion and washdown environments. For the same bore and stroke, the compact riveted body is shorter than an ISO 6432 cylinder, saving valuable mounting length. With a 1/4" port and a CA rear pivot cover, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCA Is Used
Short-Stroke Clamping
Ideal for rapidly securing heavy castings, using the 15 mm stroke and tuned air cushion to prevent impact damage on hard stops.
High-Speed Sealing
Drives heavy box sealing heads with 628.3 N of thrust, while the needle-set cushion absorbs the shock of fast repetitive motions.
Pallet Diverting
Pivots via the CA rear mount to push loaded pallets on a conveyor, handling a safe working load of 377 N without slamming.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15SCA the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your load requires less force, as it provides 402.2 N of push at 0.5 MPa. Since 40 mm is the largest bore in the MFC family, moving beyond this capacity requires a different cylinder series. The adjustable air cushion is essential for high-speed or heavy moving loads, allowing you to tune the deceleration precisely. Note that the cushion only slows the piston near the end of stroke; it does not function as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot check valve.
This specific SKU includes the -S magnet for CMSG, DMSG and EMSG sensors, and features a CA back cover for rear pivot mounting. The male rod thread is M14x1.5. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
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 MFC40X15SCA FAQ
This double-acting cylinder has a 40 mm bore, a 1/4" port, and a 16 mm rod with an M14x1.5 male 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, and a theoretical maximum force of 128.1 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. However, it cannot hold a load on air loss; the piston will drift. The variable air cushion only decelerates the piston near stroke end and acts as neither a brake nor a lock, so use an external rod lock for suspended loads.
