Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X230SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X230SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 230mm 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 MFC40X230SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy loads with ease. The 40 mm bore pairs a SUS304 stainless steel barrel with riveted aluminium covers to resist mild corrosion and washdown environments. For the same bore and stroke, the JIS-standard MFC body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
A defining feature is the variable air cushion at both ends, which uses a needle valve to soak up high-speed end-of-stroke shock, protecting the payload and cutting noise. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches, while the CM round-end back cover supports straightforward rear mounting. Based on the 0.5 MPa push rating, it provides a safe working load of about 377 N, lifting roughly 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X230SCM Is Used
Heavy Carton Diversion
Uses the 628.3 N push force to deflect heavy packed cartons on a high-speed sorting line, relying on the tuned air cushion to stop the 230 mm stroke smoothly without slamming.
Vertical Press Lowering
Lowers a 30 kg assembly head vertically, benefiting from the 2:1 safety margin lift capacity and the stainless barrel construction in a humid production area.
Pallet Flap Folding
Folds large cardboard flaps on oversized pallets, where the compact JIS body length saves machine space and the CM rear cover allows flexible pivot mounting.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X230SCM the Right Cylinder?
When sizing this 40 mm bore actuator, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as the MFC40 is the largest available bore in the series. The variable air cushion is essential when driving heavy masses at high speeds up to 800 mm/s, allowing you to tune the deceleration and prevent end-cap impact. Note that the cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If the machine loses air pressure, the piston will drift, so fit an external rod lock or pilot-operated check valve to suspend a vertical load safely. The 1/4 inch port and M14x1.5 male rod thread match standard pneumatic plumbing, and the built-in magnet enables position sensing.
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 MFC40X230SCM FAQ
This 40 mm bore double-acting cylinder features a 1/4 inch 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, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and does not act as a brake. The piston will drift if air pressure is lost. To hold a vertical load securely, you must install an external rod lock or a pilot-operated check valve.
