Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X80U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X80U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 80mm 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 MFC25X80U
Delivering 245.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the flat U rear cover allows direct flush mounting against a machine plate. For the same 25 mm bore and 80 mm stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that interface.
Featuring a 10 mm rod and a 1/8 inch port, it handles speeds of 30-800 mm/s. Based on the 0.5 MPa push rating, it provides a safe working load of about 147 N, lifting roughly 12.5 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors; choose the -S variant if you require position detection.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X80U Is Used
Package Diverting
Uses the 245.3 N push force to deflect light parcels on a high-speed sorter, with the variable air cushion preventing harsh slams at the 80 mm stroke end.
Carton Sealing
Drives a sealing head smoothly against boxes; the flat U rear cover mounts flush to the frame, saving axial space on compact packaging lines.
Light Press Fit
Applies a steady 147 N safe working load to seat small bearings, relying on the adjustable needle to decelerate the tooling before impact.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X80U the Right Cylinder?
When sizing this 25 mm bore, step down to the MFC20 for lighter duty at 157 N push @0.5 MPa, or move up to the MFC32 when you need 402.2 N. The adjustable cushion is essential for this model when driving heavier masses at high velocities, as it decelerates the piston smoothly near stroke end. Remember the cushion only slows the load; it is not a brake. If your application must hold position on air loss, add an external rod lock or pilot check valve, because the piston will drift. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion.
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 MFC25X80U FAQ
This 25 mm bore cylinder has a 1/8 inch port and a 10 mm rod. It generates 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 of 50 kgf at 1.0 MPa.
No, this SKU does not include the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant for position sensing. The SUS304 stainless build resists washdown, and the variable air cushion only decelerates the load near stroke end without locking it.
