Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCAH
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCAH 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 MFC40X150SCAH
Delivering 879.6 N of push force at 0.7 MPa, this 40 mm bore double-acting mini cylinder handles heavy loads with precision. The MFC40X150SCAH features a needle-adjustable variable air cushion at both ends, allowing you to dial in end-of-stroke deceleration to cut shock and noise at high speeds. Its JIS-standard round-body construction uses a SUS304 stainless barrel riveted to aluminium covers, resisting mild corrosion and washdown environments.
For the same 40 mm bore and 150 mm stroke, the riveted body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped from the factory with a -H high-temperature Viton seal, a -S piston magnet for CMSG/DMSG/EMSG sensors, and a CA rear pivot cover, it offers broad utility. Based on the 628.3 N push force at 0.5 MPa, it yields 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 MFC40X150SCAH Is Used
Heavy Package Diversion
Pushes heavy cartons off a high-speed main line using its 879.6 N push force, relying on the tuned air cushion to stop the 150 mm stroke smoothly without slamming.
Press Ejection
Ejects dense metal stampings from a press bed, where the 32 kg vertical lift capacity and SUS304 stainless barrel withstand oily, demanding environments.
Pallet Positioning
Indexes loaded pallets via the CA pivot mount, using the needle-set cushion to absorb the inertia of heavy goods moving at speeds up to 800 mm/s.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCAH the Right Cylinder?
When sizing this 40 mm bore unit, step down to an MFC32 if your load requires less force—it provides 402.2 N push at 0.5 MPa. Since 40 mm is the largest bore in the MFC family, moving up in force class requires switching to a different cylinder series entirely. Choose this model when moving heavy masses at high speeds, where tuning the variable air cushion is critical to prevent impact damage. It uses a 1/4" port and an M14x1.5 male rod thread.
The integrated -S magnet supports CMSG, DMSG, or EMSG electronic switches for position sensing, while the CA back cover provides a rear pivot mount. Note 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 load vertically during air loss, add an external rod lock or pilot-operated check valve, as the piston will drift otherwise.
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 MFC40X150SCAH FAQ
This 40 mm bore double-acting cylinder has 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, 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.
It features a variable air cushion at both ends that uses a needle valve to decelerate the piston near stroke end, reducing shock. The -H suffix denotes a high-temperature Viton seal, while the -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG position switches.
