Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MFC40X15CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy fast loads with a variable air cushion at both ends. An adjustable needle soaks up end-of-stroke shock, protecting the payload and cutting noise far better than a fixed rubber bumper. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the JIS-standard round body is physically shorter than an ISO 6432 cylinder for the same 15 mm stroke, saving valuable mounting length.
Equipped with a CA rear pivot cover, this specific SKU lacks a piston magnet and therefore cannot accept CMSG, DMSG, or EMSG sensors. For position feedback you must specify the -S variant. Based on the 0.5 MPa thrust, it yields a safe working load of roughly 377 N, meaning it lifts about 32 kg vertically with a 2:1 safety margin. The 1/4" port matches the 40 mm bore class to supply adequate airflow for high-speed cycling.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CA Is Used
Short-Stroke Stamping
Uses the 879.6 N peak thrust at 0.7 MPa to execute rapid 15 mm stamping or crimping tasks, relying on the tuned air cushion to absorb the sudden halt at stroke end.
Heavy Divertor Arm
Swings a substantial divertor mechanism via the CA pivot cover, using the 377 N safe working load to push heavy packages without slamming the pivot joint.
Washdown Carton Sealer
Cycles rapidly in a humid packaging line where the SUS304 stainless barrel prevents mild corrosion and the adjustable cushion protects delicate cardboard flaps from impact.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X15CA the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive for your payload, step down to the MFC32, which provides 402.2 N; since 40 mm is the largest bore in the MFC family, moving up requires a different cylinder series. The variable air cushion is essential when driving heavy masses at high speeds, as the needle valve lets you tune the deceleration curve to prevent end-cap slamming. This cylinder cannot hold position on air loss, as the piston drifts when pressure drops or the valve centers. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, but remember this base unit has no magnet for 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 MFC40X15CA FAQ
This 40 mm bore, 15 mm stroke double-acting 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, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must select the -S variant for sensing. Additionally, the variable air cushion only decelerates the piston near the stroke end and does not function as a brake or lock to hold the load.
