Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 90mm 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 MFC40X90CA
Taming heavy shocks at high cycle rates is the core strength of the MFC40X90CA, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. As the largest bore in the series, it generates a robust 628.3 N push force at 0.5 MPa, scaling up to a theoretical maximum of 128.1 kgf at 1.0 MPa. A needle-set variable air cushion at both ends absorbs end-of-stroke impact, protecting your machinery where a fixed bumper would fail. For the same 40 mm bore and 90 mm stroke, this riveted construction is notably shorter than an ISO 6432 cylinder, saving valuable mounting length.
Featuring a 16 mm piston rod, an M14x1.5 male thread, and a 1/4" port, this double-acting actuator is engineered for demanding dynamics. The SUS304 barrel provides reliable mild corrosion and washdown resistance. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position sensors. It includes a CA rear pivot cover for articulated mounting.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90CA Is Used
High-Speed Package Diverting
Uses the 628.3 N thrust to push heavy cartons off a main belt at 800 mm/s, relying on the adjustable air cushion to stop the 90 mm stroke without slamming.
Pallet Strapping Press
Delivers steady downward pressure for strapping heads, with the CA pivot accommodating slight misalignment while the SUS304 barrel resists dust.
Stamping Pin Feed
Cycles a heavy marking pin into position, using the needle-set deceleration to protect the tooling over millions of high-impact repetitions.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90CA the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push force at 0.5 MPa against the smaller MFC32, which yields 402.2 N; since 40 mm is the largest available MFC bore, moving up requires switching to a different cylinder family. The variable air cushion is essential if your 90 mm stroke operates at high speeds or moves a heavy mass, as it allows you to dial in the exact deceleration to prevent end-cap damage. Keep in mind the cushion only decelerates the piston near the stroke end; it is not a brake. If the application must hold position on air loss, you must add an external rod lock or pilot check valve, as the piston will drift. This base model has no magnet, so position sensing is unavailable unless you switch to an -S variant.
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 MFC40X90CA FAQ
This 40 mm bore double-acting cylinder features a 1/4" air 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. The cylinder features a CA rear pivot cover and a variable air cushion at both ends to tune end-of-stroke deceleration.
