Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X650SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X650SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 650mm 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 MFC40X650SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting MFC40X650SCM handles heavy loads with precision. It is a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length. This specific 650 mm stroke is a non-standard, made-to-order configuration exceeding the 500 mm standard maximum.
A defining feature is the variable air cushion at both ends, allowing you to turn a needle to soak up high-speed end-of-stroke shock, protecting the load and cutting noise. The -S suffix adds a built-in piston magnet for CMSG, DMSG or EMSG switches, while the CM back cover provides a round-end rear mounting style. Derived from the 0.5 MPa push rating, the safe working load is about 377 N, meaning it lifts roughly 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X650SCM Is Used
Long-Stroke Diverting
Pushes heavy pallets sideways across a 650 mm gap, using the variable air cushion to halt the 628.3 N thrust smoothly without slamming.
Vertical Material Lowering
Lowers 30 kg fixtures safely, relying on the adjustable end cushioning to prevent harsh drops at the bottom of the 650 mm travel.
Large Carton Forming
Actuates large format packaging tooling where the riveted SUS304 body withstands mild washdown and the long stroke accommodates oversized boxes.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X650SCM the Right Cylinder?
When sizing, step down to the MFC32 if your load requires less than 402.2 N at 0.5 MPa, as the MFC40 is the largest bore available in this series. The variable air cushion is essential here for a 650 mm stroke moving heavy masses at high speed, preventing harsh impacts. Keep in mind the cushion only decelerates near the stroke end; it does not function as a lock or brake. If the load must be held on air loss, install an external rod lock or pilot-operated check valve.
This SKU includes the -S magnet for position sensing and the CM round-end back cover. The 1/4" port matches the 40 mm bore. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MFC40X650SCM FAQ
The 40 mm bore uses a 1/4" port. 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 of 128.1 kgf at 1.0 MPa.
No. The variable air cushion only decelerates the piston near the stroke end and is not a brake. On air loss the piston will drift; use an external rod lock or pilot check valve to hold loads. The -S magnet enables CMSG/DMSG/EMSG sensors.
