Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X290SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X290SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 290mm 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 MFC40X290SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles demanding actuation with a 290 mm stroke. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position feedback, while the CM round-end rear cover completes the JIS-standard round-body layout. A 1/4" port supplies air to the 16 mm piston rod.
A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock at high speeds, protecting the load and cutting noise. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard. Based on the 0.5 MPa push rating, it handles a safe working load of about 377 N, lifting roughly 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X290SCM Is Used
Heavy Package Diversion
Pushes loaded pallets off a high-speed line; the tuned air cushion halts the 16 mm rod smoothly to prevent jarring impacts.
Carton Flap Folding
Drives folding arms on large packaging equipment, using the 628.3 N force to handle thick cardboard without bouncing.
Component Pressing
Seats bearings or pins into housings, relying on the adjustable end cushions to decelerate the load gently at the bottom of the stroke.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X290SCM the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive, the smaller MFC32 bore provides 402.2 N; as 40 mm is the largest available MFC bore, moving up requires an alternative series. Choose this 40 mm model when moving heavier masses at high speeds, where tuning the variable air cushion prevents harsh end-of-stroke impacts. Note that the cushion only decelerates the piston near the stroke end—it is not a brake. If the load must be held during air loss or valve centering, fit an external rod lock or pilot-operated check valve to prevent drift. 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 MFC40X290SCM FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod. 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, the variable air cushion only decelerates the piston near the end of the stroke and does not act as a lock or brake. If air is lost, the piston will drift. For vertical loads, install an external rod lock or pilot-operated check valve. The -S magnet allows CMSG, DMSG, and EMSG switches to track position.
