Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCMLB
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCMLB 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 MFC32X400SCMLB
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles long 400 mm strokes while smoothing out high-speed impacts via its needle-set variable air cushion at both ends. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown. For the same bore and stroke, this JIS-standard round-body design is physically shorter than an ISO 6432 cylinder, saving valuable machine space without sacrificing reach.
Equipped with a built-in piston magnet (-S), it supports CMSG, DMSG and EMSG switches for position sensing. With a safe working load of roughly 241 N, it can vertically lift about 20.5 kg with a 2:1 safety margin. The unit features a CM round-end rear cover, an LB foot mount, an M10x1.25 male rod thread, and a 1/4" port.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCMLB Is Used
Carton Diverting
Pushes packages along a sorting line over a 400 mm span, relying on the variable air cushion to silently absorb the impact of rapid 402.2 N strokes.
Vertical Lift Gate
Raises a 20 kg access panel using the 2:1 safety margin, where the LB foot mount and CM round-end cover provide stable anchoring.
Film Roll Feed
Shifts heavy packaging material rolls into position, using the needle adjustment to prevent sudden jolts from damaging the web at high speed.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SCMLB the Right Cylinder?
If 245.3 N of push at 0.5 MPa from the MFC25 is insufficient, this 32 mm bore provides 402.2 N; should your payload require even more force, step up to the MFC40 which yields 628.3 N. The adjustable air cushion is essential when moving heavy loads at high speeds across the 400 mm travel, as it decelerates the piston to prevent end-of-stroke shock.
Note that the air cushion only decelerates near the stroke end and does not function as a lock or brake; the piston will drift if air is lost or the valve is centred. For load-holding safety, install an external rod lock or a pilot-operated check valve. The included LB foot mount secures the body, while the -S magnet enables direct sensor mounting.
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 MFC32X400SCMLB FAQ
This 32 mm bore model features a 1/4" port and an M10x1.25 male rod 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, the piston will drift on air loss since the variable air cushion only decelerates near stroke end and acts as neither a lock nor a brake. For vertical loads, you must use an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to confirm position.
