Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X75S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X75S is a genuine double acting, double rod + 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 MFCD Double Rod Cushioned Mini Cylinder MFCD25X75S
Twin rods exit both covers of the AirTAC MFCD25X75S, delivering equal thrust in both directions while actively resisting side-play and rotation. As a JIS-standard round-body mini cylinder with a SUS304 stainless barrel and riveted aluminium covers, it is notably shorter than an ISO 6432 unit of the same 25 mm bore and 75 mm stroke, saving valuable machine space. A needle-set variable air cushion at each end absorbs high-speed end-of-stroke shock for quiet operation.
The twin 10 mm rods share a male M10x1.25 thread and provide a robust mounting point for a second tool or stopper. Because the -S suffix includes a built-in piston magnet, this version supports CMSG, DMSG, and EMSG position switches. Delivering 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa both ways, it yields a safe working load of roughly 124 N or a 2:1 vertical lift margin of about 10.5 kg. Air connects via 1/8" ports.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X75S Is Used
Twin-Tool Transfer
Uses the dual M10x1.25 rods to mount opposing grippers, moving 10 kg electronics trays horizontally at high speed with equal push and pull thrust.
Cushioned Press Down
Lowers a 124 N stamping head smoothly, relying on the variable air cushion to prevent harsh mechanical crashes at the bottom of the 75 mm stroke.
Anti-Rotation Diverter
Pushes and retracts a sorting flap on a packaging line, using the second rod to keep the mechanism perfectly steady during fast 800 mm/s cycles.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X75S the Right Cylinder?
When sizing between the available bores, this 25 mm option outputs 206.1 N at 0.5 MPa, sitting neatly between the MFCD20 at 131.9 N and the MFCD32 at 345.6 N. Choose the 25 mm bore when your application needs moderate lifting power alongside the precise anti-rotation guidance that only a double-rod build provides, especially for high-speed cycles where the adjustable air cushion prevents harsh impacts.
The -S magnet enables CMSG, DMSG, or EMSG sensors for end-position confirmation, and you can mount via LB foot, FA flange, or TC trunnion. Remember that the air cushion only decelerates the piston near the stroke end; it does not lock or hold the load. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads.
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 MFCD Double Rod Cushioned Mini Cylinder MFCD25X75S FAQ
Because it is a double-rod cylinder, the force is equal in both directions using the rod-side area. It generates 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa. The theoretical maximum force is 42 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke to reduce shock; it does not act as a brake or lock. If you need to hold a suspended load vertically, you must add an external rod lock or pilot-operated check valve. The -S magnet allows CMSG, DMSG, or EMSG sensors to confirm position.
