Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 85mm stroke, 1/8" 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 MFC25X85SU
Tuned for rapid cycling, this double-acting JIS-standard round-body mini cylinder uses a variable air cushion at both ends to soak up high-speed end-of-stroke shock. The 25 mm bore generates 245.3 N of push force at 0.5 MPa, yielding a safe working load of roughly 147 N and a vertical lift capacity of about 12.5 kg with a 2:1 margin. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown.
For the same 85 mm stroke and 25 mm bore, this MFC body is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length. The U flat-end rear cover provides a flush back for direct mounting, while the included -S piston magnet enables position sensing with CMSG, DMSG or EMSG switches. Air connects via 1/8" ports.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SU Is Used
Package Diverting
Ideal for rapidly deflecting light parcels on a sorting line where the 245.3 N push force and end-cushioning prevent harsh impacts at 85 mm stroke.
Film Sealing Press
Drives a sealing jaw at high cycle rates; the needle-tuned air cushion ensures the 12.5 kg vertical load decelerates cleanly without crushing the packaging.
Component Insertion
Pushes bearings or pins into housings on an assembly machine, using the -S magnet and DMSG switch to confirm the 85 mm insertion stroke completed.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SU the Right Cylinder?
When sizing this 25 mm bore, step down to the MFC20 if your load requires just 157 N of push force at 0.5 MPa, or move up to the MFC32 which provides 402.2 N for heavier payloads. The adjustable needle cushion is essential when operating at high speeds or moving substantial mass, as it decelerates the piston smoothly to protect the load. Note that this air cushion only slows the piston near stroke end and does not function as a lock or brake.
Because a standard double-acting cylinder drifts when air pressure drops or the valve is centered, you must add an external rod lock or pilot-operated check valve to hold a vertical load securely. This U back cover model is magnet-ready (-S) for CMSG/DMSG/EMSG sensors, and you can mount it using LB foot, FA flange, SDB pivot or 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 MFC25X85SU FAQ
This 25 mm bore cylinder has a 1/8" port and an M10x1.25 male rod thread. It delivers 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum force of 50 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of its stroke and acts purely as a shock absorber, never as a brake or lock. If you need to prevent drift on a vertical load during air loss, install an external rod lock or pilot check valve. The SUS304 stainless barrel also provides excellent washdown resistance.
