Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X90SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X90SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 90mm 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 MFC25X90SU
Dial in end-of-stroke deceleration with the AirTAC MFC25X90SU, a JIS-standard round-body mini cylinder built for high-speed actuation. The variable air cushion at both ends lets you turn a needle to soak up shock, protecting the load and cutting noise versus a bumper mini. A built-in magnet (-S) enables CMSG, DMSG or EMSG switches for position sensing, while the U flat-end back cover suits direct mounting.
This double-acting 25 mm bore unit pushes 245.3 N and pulls 206.1 N at 0.5 MPa, yielding a safe working load of about 147 N. It lifts roughly 12.5 kg vertically with a 2:1 margin. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable machine space. The 1/8 inch port and M10x1.25 male rod thread streamline integration.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X90SU Is Used
Package Diverting
Shifts small cartons at high speed onto secondary lines, relying on the needle-set cushion to halt the 90 mm stroke smoothly without jarring the belt.
Component Seating
Presses lightweight bearings into housings, using the 245.3 N push force at 0.5 MPa to seat parts precisely while the U flat-end cover handles rear mounting.
Vertical Tray Lifting
Elevates stacked product trays, lifting around 12.5 kg safely with a 2:1 margin while the -S magnet tracks position via DMSG sensors.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X90SU the Right Cylinder?
When sizing this 25 mm bore actuator, step down to the MFC20 if your task requires less than 157 N of push force at 0.5 MPa, or move up to the MFC32 when you need 402.2 N to drive heavier payloads. The adjustable air cushion is essential for the 30-800 mm/s speed range, preventing harsh impacts when moving substantial mass. Note that the cushion only decelerates the piston near stroke end; it does not lock the rod. If your system must hold a load vertically during air loss or valve centering, add an external rod lock or pilot-operated check valve. Choose LB foot, FA flange, SDB pivot or TC trunnion mounts to fit 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 MFC25X90SU FAQ
This double-acting cylinder has a 25 mm bore, a 10 mm rod, and a 1/8 inch port. 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. Operating pressure spans 0.15-1.0 MPa.
The variable air cushion at both ends uses a needle to absorb high-speed end-of-stroke shock, reducing noise and load damage. It only decelerates the piston and is not a brake. The SUS304 stainless barrel and riveted aluminium covers provide mild corrosion and washdown resistance.
