Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SCM 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 MFC25X85SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder is built for demanding 25 mm bore tasks. The adjustable air cushion at both ends allows you to dial in end-of-stroke deceleration, absorbing high-speed shocks that a fixed bumper cannot handle. A 1/8" port feeds the chamber, and the riveted SUS304 stainless barrel with aluminium covers resists mild corrosion.
Because the body is shorter than a comparable ISO 6432 cylinder for the same 85 mm stroke, it saves valuable mounting space. The CM round-end rear cover and integrated -S magnet round out the hardware. The -S magnet enables direct mounting of CMSG, DMSG, or EMSG sensors for position detection. In practical terms, it yields a safe working load of about 147 N, or roughly 12.5 kg of vertical lift with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SCM Is Used
Package Diverting
Uses the 245.3 N push force to deflect parcels at high speed, relying on the needle-set air cushion to prevent harsh slams at the 85 mm stroke end.
Small Press Fitment
Inserts lightweight bearings with controlled force, where the adjustable deceleration protects delicate components from impact shock.
Vertical Tray Lifting
Raises component trays weighing up to 12.5 kg, using the -S magnet and DMSG sensors to confirm elevation before releasing.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X85SCM the Right Cylinder?
When sizing this 25 mm bore unit, step down to the MFC20 for lighter loads at 157 N push @0.5 MPa, or move up to the MFC32 if you need 402.2 N @0.5 MPa. This model hits a solid middle ground for mid-range force. The variable air cushion is essential when cycling at high speeds or moving heavy masses, as it prevents harsh end-of-stroke impacts.
Note that the air cushion only decelerates the piston near the stroke end; it is not a brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve. You can mount this unit using LB foot, FA flange, SDB pivot, or TC trunnion hardware to suit your frame.
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 MFC25X85SCM FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of travel and does not act as a lock or brake. If air loss occurs, the piston will drift. For suspended loads, install an external rod lock or pilot check valve. The SUS304 stainless build and -S magnet for CMSG switches ensure reliable operation in mild washdowns.
