Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X165SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X165SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 165mm 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 MFC40X165SCA
Delivering up to 879.6 N of push force at 0.7 MPa, this double-acting 40 mm bore mini cylinder handles heavy loads with precision. The MFC40X165SCA features a needle-adjustable variable air cushion at both ends, allowing you to dial in end-of-stroke deceleration to cut shock and noise during high-speed cycles. Its JIS-standard round-body construction uses a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments.
For the same bore and stroke, this riveted stainless design is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped with a 1/4" port and an M14x1.5 male rod thread, it yields a safe working load of about 377 N (roughly 60% of the 0.5 MPa push force), lifting around 32 kg vertically with a 2:1 margin. The -S suffix adds a piston magnet for position sensing, while the CA back cover provides a rear pivot mount.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X165SCA Is Used
Heavy Package Diverting
Pushes dense cartons at high speed on a sorting line, using the variable air cushion to halt the 628.3 N stroke smoothly without jarring the belt.
Vertical Load Lowering
Lowers a 30 kg fixture safely, relying on the needle-adjustable deceleration to prevent a hard bottoming impact at the end of the 165 mm stroke.
Press Fit Assembly
Drives a heavy bearing into a housing, applying steady force and using the CA pivot mount to accommodate slight misalignment during the press cycle.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X165SCA the Right Cylinder?
When sizing this 40 mm bore unit, step down to an MFC32 if your load requires less force, as the 32 mm version provides 402.2 N of push at 0.5 MPa. Since 40 mm is the largest bore in the MFC family, you cannot size up within this series; exceeding the 128.1 kgf theoretical maximum at 1.0 MPa would require a different cylinder family entirely. Choose this model when moving heavy masses at high speeds where the adjustable air cushion is essential to prevent impact damage.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a load vertically during air loss or when a valve is centered, the piston will drift, requiring an external rod lock or pilot-operated check valve. The included -S magnet supports CMSG, DMSG, or EMSG switches, and the built-in CA pivot bracket simplifies angular mounting.
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 MFC40X165SCA FAQ
This 40 mm bore cylinder features 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.
No, the variable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never as a brake or lock; the piston will drift on air loss, so you need an external rod lock or pilot check valve to hold a load. The -S suffix indicates a built-in piston magnet, enabling the use of CMSG, DMSG, or EMSG reed or electronic switches for position sensing.
