Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X40
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X40 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 40mm 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 MFCD25X40
Twin rods exit both covers on the AirTAC MFCD25X40, yielding equal 206.1 N thrust in both directions at 0.5 MPa while steadying the load against rotation. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a mounting envelope that is actually shorter than an ISO 6432 unit of the same bore and stroke.
A needle-set variable air cushion at each end absorbs high-speed end-of-stroke shock across the 30-800 mm/s range, keeping operations quiet. This non-magnet SKU cannot host a sensor; adding the -S option enables CMSG, DMSG or EMSG switches. The 1/8" port and M10x1.25 male rod threads simplify integration. For vertical lifts, expect to handle about 10.5 kg each way with a 2:1 safety margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X40 Is Used
Twin-Tool Transfer
Drive a dual pick-and-place head at 206.1 N both ways, using the second rod to mount a stopper while the cushion softens 40 mm strokes.
Anti-Rotation Indexing
Move a small machining fixture without side-play; the twin 10 mm rods resist twist and the variable air cushion handles rapid 30-800 mm/s cycling.
Compact Carton Sealing
Save machine length compared to ISO 6432 while pushing a sealing jaw with 288.5 N at 0.7 MPa, relying on equal pull to retract smoothly.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD25X40 the Right Cylinder?
Choose the MFCD25X40 when you need more muscle than the MFCD20 (131.9 N at 0.5 MPa) but want to avoid the bulk of an MFCD32 (345.6 N at 0.5 MPa). The 25 mm bore hits a sweet spot for moderate pushing and pulling. Its double-rod architecture is ideal for high-speed anti-rotation tasks or mounting twin tools, while the adjustable air cushions prevent harsh impacts at the 40 mm stroke ends.
Remember that the air cushion only decelerates the piston near the end of travel; it does not function as a brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot check valve. For position feedback, select the -S magnet variant to support CMSG, DMSG or EMSG sensors, and mount via LB foot, FA flange or TC trunnion (no SDB or back-cover code exists).
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 MFCD25X40 FAQ
Because it is a double-rod cylinder, the force is equal both ways (rod-side area). It generates 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa in both directions. The theoretical maximum force is 42 kgf at 1.0 MPa. It uses a 1/8" port and M10x1.25 male rod threads.
No, this specific SKU lacks a magnet and cannot take a magnetic switch. You must choose the -S variant to use CMSG, DMSG or EMSG sensors. The unit features a variable air cushion at both ends for smooth deceleration and twin rods for anti-rotation, but the cushion only absorbs shock and does not lock the load.
