Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X135SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X135SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 135mm 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 MFC40X135SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder is built for demanding high-speed tasks. The MFC40X135SU features a variable air cushion at both ends, letting you dial in a needle valve to absorb end-of-stroke shock and protect your payload. Its JIS-standard round-body construction uses a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments.
Thanks to the riveted rolling-packed design, the overall body is shorter than an ISO 6432 cylinder for the same 135 mm stroke, saving valuable mounting space. The included -S piston magnet enables CMSG, DMSG, or EMSG position sensing, while the U flat-end back cover provides a flush rear mounting face. Operating pressure spans 0.15 to 1.0 MPa, and the 1/4 inch port handles ample airflow for the 30-800 mm/s speed range.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X135SU Is Used
Package Diverting
Handles heavy carton redirection on high-speed lines where the variable air cushion silently absorbs the 628.3 N end-of-stroke impact.
Vertical Lowering
Lowers 30 kg fixtures smoothly; the adjustable cushion prevents slamming at the bottom of the 135 mm stroke.
Clamp Actuation
Drives robust clamping mechanisms in machining stations, using the U flat-end cover for flush rear mounting.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X135SU the Right Cylinder?
When sizing this 40 mm bore, look both ways: stepping down to the MFC32 yields 402.2 N of push force at 0.5 MPa, while no larger MFC bore exists for heavier demands. The variable air cushion is essential when moving substantial masses at high velocities, as it decelerates the piston smoothly before the end of stroke. Remember that the cushion only slows the load near the end of travel; it does not function as a lock or brake. If your application must hold position on air loss, install an external rod lock or pilot-operated check valve.
This MFC40X135SU configuration includes the -S magnet for direct sensor mounting and a U flat-end back cover. You can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets to suit your frame. With a safe working load of roughly 377 N (about 60% of the 0.5 MPa push figure), it can vertically lift about 32 kg with a 2:1 safety margin.
Quick checklist

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 MFC40X135SU FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push is 879.6 N and pull is 738.9 N. 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 never acts as a lock or brake. The piston will drift if air is lost. For load holding, you must add an external rod lock or pilot check valve. The SUS304 stainless barrel provides washdown resistance, and the -S magnet supports CMSG/DMSG/EMSG sensors.
