Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MFC40X150SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder tackles heavy loads with precision. The MFC40X150SCA features a needle-set variable air cushion at both ends, allowing you to dial in the deceleration and eliminate end-of-stroke shock during high-speed 150 mm strokes. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, this JIS-standard round-body cylinder is notably shorter than an ISO 6432 unit, saving valuable mounting length. The built-in -S piston magnet supports CMSG, DMSG, and EMSG switches for position sensing, while the CA rear pivot cover simplifies direct rear mounting. With a 1/4" port and an M14x1.5 male rod thread, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCA Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons at high speed, relying on the adjustable air cushion to stop the 150 mm stroke smoothly without slamming.
Press Ejection System
Ejects dense stamped parts from a press bed, where the SUS304 stainless barrel withstands residual cutting fluids and the CA pivot absorbs lateral moments.
Pallet Positioning Gate
Actuates a heavy pallet routing gate; the -S magnet confirms extension via a DMSG sensor, while the compact JIS body fits tight conveyor frame clearances.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCA the Right Cylinder?
If 628.3 N of push at 0.5 MPa is excessive for your payload, step down to the MFC32, which provides 402.2 N; conversely, the 40 mm bore is the largest available in this series, making it the top choice for maximum thrust within the compact mini cylinder format. The variable air cushion is essential when moving heavy masses at high operating speeds up to 800 mm/s, as it protects the load from harsh impacts. Keep in mind the cushion only decelerates the piston near the stroke end—it is not a brake. If your application must hold position during air loss, add an external rod lock or pilot-operated check valve. The -S magnet enables CMSG/DMSG/EMSG sensors, and you can pair the CA back cover with LB foot, FA flange, or TC trunnion mounts for versatile installation.
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 MFC40X150SCA FAQ
This 40 mm bore cylinder uses a 1/4" port and an M14x1.5 male rod thread. 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.
The variable air cushion at both ends uses a needle valve to trap and bleed exhaust air, decelerating the piston to prevent high-speed shock. It is not a lock or brake, so the piston will drift if air pressure is lost; use an external rod lock or pilot check valve for load holding. The -S magnet allows CMSG/DMSG/EMSG switches for position feedback.
