Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MFC32X400CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles a 400 mm stroke while keeping shock firmly in check. A variable air cushion at both ends lets you dial in the needle to decelerate heavy loads at high speeds, actively protecting the workpiece and cutting workshop noise.
Built with a SUS304 stainless barrel and riveted aluminium covers, the JIS-standard round-body design resists mild corrosion and washdown. For the same bore and stroke, it is notably shorter than an ISO 6432 cylinder. This base SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG sensors; add the -S variant for position detection. The rear uses a CM round-end cover, and the air port is 1/4".

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400CM Is Used
Package Diverting
Shifts medium-weight cartons across sorting lanes at speed, using the variable cushion to stop the 400 mm travel without jarring the belt.
Box Flap Folding
Drives folding arms on a packaging line where the 402.2 N push force easily overcomes cardboard resistance for clean closures.
Vertical Tray Lifting
Raises loaded component trays; the needle-set cushion prevents the load from slamming at the top of the 400 mm extension.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400CM the Right Cylinder?
When sizing this 32 mm bore, step down to the MFC25 for lighter duties at 245.3 N push @0.5 MPa, or move up to the MFC40 when you need 628.3 N. The variable cushion is essential for this 400 mm stroke if you cycle near the 800 mm/s limit, as it absorbs end-of-stroke impact. Based on the 0.5 MPa figure, the safe working load is roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin.
Mounting options include LB foot, FA flange, SDB pivot and TC trunnion brackets. Remember that the air cushion only decelerates the piston near the stroke end; it does not lock or hold the load. If air pressure drops, the rod will drift. To hold a vertical load securely, install an external rod lock or a pilot-operated check valve.
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 MFC32X400CM FAQ
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod with an M10x1.25 male thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches will not function. You need the -S variant for sensing. The SUS304 stainless build and CM round-end cover suit harsher environments, and the variable air cushion decelerates the rod but does not act as a brake.
