Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X75SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X75SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 75mm 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 MFC25X75SU
Dial in end-of-stroke deceleration with the AirTAC MFC25X75SU, a JIS-standard round-body mini cylinder built for high-speed actuation. The variable air cushion at both ends uses a needle to absorb shock, protecting your payload far better than a fixed bumper. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Generating 245.3 N of push force at 0.5 MPa, this double-acting actuator is a robust mid-range choice. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors, while the flat U back cover suits tight axial spaces. For the same 25 mm bore and 75 mm stroke, this compact body is shorter than an ISO 6432 cylinder, saving valuable mounting length.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X75SU Is Used
Package Diverting
Handles fast 75 mm sorting strokes on conveyors where the adjustable air cushion silently stops the 245.3 N thrust without jarring the products.
Light Press Fit
Ideal for seating small bearings or pins, using the flat U rear cover for flush mounting and the cushion to prevent impact damage on contact.
Vertical Lift Stops
Lifts roughly 12.5 kg vertically with a 2:1 safety margin, while the needle-set deceleration protects suspended loads from sudden drops at stroke end.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X75SU the Right Cylinder?
When sizing this 25 mm bore, check both extremes: step down to the MFC20 for lighter 157 N tasks, or move up to the MFC32 when you need 402.2 N of push force at 0.5 MPa. The variable cushion is essential when cycling at high speeds or moving heavy masses, as it prevents harsh impacts. The 1/8" port and M10x1.25 male rod thread simplify integration.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If your system loses air, the piston will drift, so fit an external rod lock or pilot check valve for secure load holding. The included -S magnet enables position sensing.
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 MFC25X75SU FAQ
This double-acting cylinder features a 1/8" port and delivers 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 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 the stroke and acts as neither a lock nor a brake. On air loss the piston will drift, so you must use an external rod lock or pilot check valve to hold a load. The -S magnet allows CMSG/DMSG/EMSG sensors for position feedback.
