Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 220mm 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 MFC40X220CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder tackles heavy loads with precision. The MFC40X220CM features a variable air cushion at both ends, allowing you to dial in a needle valve to absorb high-speed end-of-stroke shock, protecting your machinery and reducing noise far better than a fixed rubber bumper. Built with a SUS304 stainless steel barrel and riveted aluminium covers, it resists mild corrosion and washdown environments. Furthermore, its JIS-standard round-body construction is noticeably shorter than an ISO 6432 cylinder for the same 220 mm stroke, saving valuable mounting length.
Equipped with a 1/4" port and a 16 mm rod with an M14x1.5 male thread, this model yields a safe working load of about 377 N (60% of its 0.5 MPa push force). In a vertical setup, it lifts roughly 32 kg with a 2:1 safety margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors; add the -S variant if you require piston detection. The CM round-end back cover provides a clean, versatile rear mounting interface for your assembly.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220CM Is Used
Heavy Package Diversion
Uses the full 628.3 N push force to positively redirect heavy cartons on a high-speed sorting line, with the variable cushion preventing harsh slams during rapid cycling.
Pallet Flap Folding
Folds large cardboard flaps on oversized pallets where the 40 mm bore provides the necessary torque, relying on the 220 mm stroke to clear tall loads.
Press Ejection
Ejects dense formed parts from a press bed, using the adjustable end-cushioning to softly decelerate the 16 mm rod before it strikes the machine frame.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220CM the Right Cylinder?
When sizing this 40 mm bore model, evaluate your force needs bidirectionally. If 628.3 N at 0.5 MPa is excessive, stepping down to the MFC32 provides 402.2 N, saving space and air. Since 40 mm is the largest available MFC bore, exceeding this capacity requires multiple cylinders or a different series entirely. The variable air cushion is essential when cycling at high speeds or moving heavy masses, as it prevents harsh impact at the stroke ends.
Remember that the air cushion only decelerates the piston near the end of travel; it is not a brake. If the air supply drops or the valve is centered, the piston will drift, so you must fit an external rod lock or pilot-operated check valve to hold a suspended load. For mounting flexibility, you can utilize LB foot, FA flange, SDB pivot, or TC trunnion brackets, but note that this non-magnetized version cannot support sensing switches.
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 MFC40X220CM 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, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, its SUS304 stainless round-body is shorter than an ISO 6432 cylinder, and the needle-set air cushion only decelerates the load at stroke end without locking position.
