Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFC40X160SCM
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy loads with precision. The MFC40X160SCM features a variable air cushion at both ends, allowing you to needle-tune the end-of-stroke deceleration to absorb high-speed shock, protecting your machinery and reducing noise. Its JIS-standard round-body construction uses a SUS304 stainless steel barrel with riveted aluminium covers, offering excellent mild corrosion and washdown resistance.
For the same bore and stroke, this riveted stainless design is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting space. Equipped with a 1/4" port and a 16 mm rod, it generates a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin. The -S suffix denotes a built-in piston magnet for position sensing, while the CM back cover provides a specific round-end rear mounting profile.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SCM Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons on a high-speed sorting line, relying on the tuned air cushion to stop the 160 mm stroke smoothly without slamming.
Press Ejection System
Ejects dense metal or plastic parts from a press bed, where the needle-set variable cushion absorbs the sudden deceleration of the 40 mm bore at high cycling speeds.
Pallet Stopper Gate
Acts as a robust pneumatic stop gate for loaded pallets, utilizing the SUS304 stainless barrel to withstand dusty industrial environments and occasional washdowns.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SCM the Right Cylinder?
When sizing this 40 mm bore unit, consider that the smaller MFC32 provides 402.2 N of push force at 0.5 MPa, making this MFC40X160SCM the top choice when you need the maximum 628.3 N available in the series. The variable air cushion is essential when operating at high speeds or moving heavy masses, as it prevents harsh end-of-stroke impacts. Remember that the cushion only decelerates the piston near the stroke end; it does not function as a lock or brake.
Because a standard double-acting cylinder drifts when air pressure is lost or a valve is centered, you must integrate an external rod lock or a pilot-operated check valve to hold a suspended load safely. This specific SKU includes the -S magnet for CMSG, DMSG, or EMSG switches. Mounting flexibility is provided via the CM round-end back cover, along with standard LB foot, FA flange, SDB pivot, and TC trunnion options.
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 MFC40X160SCM FAQ
This 40 mm bore double-acting cylinder uses a 1/4" air port. At 0.5 MPa it provides 628.3 N of push force and 527.8 N of pull force. At 0.7 MPa, the push force is 879.6 N and the pull force is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. However, the variable air cushion only decelerates the piston near the stroke end; it is not a brake. The cylinder will drift on air loss, so an external rod lock or pilot check valve is required to hold a vertical load safely.
