Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X50S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X50S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 50mm 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 MFCD25X50S
Twin rods exit both covers of the AirTAC MFCD25X50S, delivering equal 206.1 N force at 0.5 MPa in both directions while actively resisting load rotation. A needle-set variable air cushion at each end soaks up high-speed end-of-stroke shock, ensuring quiet deceleration across its 50 mm travel. This JIS-standard round-body mini relies on a SUS304 stainless barrel with riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same size and resisting mild washdown corrosion.
Fitted with a piston magnet (-S), this 25 mm bore model accepts CMSG, DMSG or EMSG switches for position sensing. It pushes a theoretical maximum of 42 kgf at 1.0 MPa through its M10x1.25 male rod threads, operating at 30-800 mm/s. For sizing context, a safe working load is roughly 124 N, letting you vertically lift about 10.5 kg each way with a 2:1 margin. The unit uses a 1/8" port and includes no back cover, meaning no SDB mount exists.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X50S Is Used
Twin-Tool Stamping
Drives two synchronized forming tools from a single body, using the 206.1 N bidirectional thrust to press and release lightweight components without rotational skew.
High-Speed Divertor
Rapidly redirects small packages on a belt line, relying on the variable air cushions to absorb the 800 mm/s end-of-stroke impact for quiet operation.
Vertical Lift Gate
Raises and lowers a 10 kg access flap with equal force both ways, while the second rod stabilizes the load to prevent binding during vertical travel.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X50S the Right Cylinder?
Choose this MFCD25X50S over the smaller MFCD20 when you need more muscle: it outputs 206.1 N both ways at 0.5 MPa versus 131.9 N for the 20 mm bore. If your application requires even greater thrust, stepping up to the MFCD32 provides 345.6 N. This 25 mm bore is ideal for high-speed twin-tool setups where the double-rod geometry prevents yawing and the adjustable cushions protect sensitive payloads.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If gravity or air loss might cause the load to drift, install an external rod lock or pilot check valve. For mounting, select LB foot, FA flange or TC trunnion brackets, and leverage the built-in magnet for direct CMSG or DMSG sensor mounting.
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 MFCD25X50S FAQ
It delivers equal force in both directions because of the double-rod design: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa. The air port size is 1/8".
The variable air cushions at both ends only decelerate the piston near stroke end to reduce shock; they do not lock or hold the load on air loss. Because this is an -S model with a built-in magnet, you can directly mount CMSG, DMSG or EMSG sensors for position detection.
