Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X40
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X40 is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm stroke, 1/4" 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 MFCD32X40
Twin rods exit both covers on the AirTAC MFCD32X40, yielding equal 345.6 N force at 0.5 MPa in both directions while actively resisting side-play and rotation. A needle-set variable air cushion at each end absorbs end-of-stroke shock, allowing quiet, high-speed operation up to 800 mm/s. Built as a JIS-standard round-body mini cylinder, its SUS304 stainless barrel and riveted aluminium covers provide reliable mild corrosion and washdown resistance.
This 32 mm bore unit features a 12 mm rod at each end, M10x1.25 male rod threads, and a 1/4" air port. Because the body is shorter than an ISO 6432 cylinder of identical bore and stroke, it saves valuable mounting length without conforming to that standard. The cushion only decelerates the piston near stroke end and does not lock the load; for vertical lifts up to roughly 17.6 kg with a 2:1 margin, add an external rod lock or pilot check valve to prevent drift on air loss.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X40 Is Used
Twin-Tool Transfer
Drives a dual-pick gripper moving light electronics parts between conveyor lanes at high speed, using the equal 345.6 N bidirectional force to push and pull without reorienting the tool.
Anti-Rotation Indexing
Shifts a small machining fixture back and forth rapidly, relying on the second rod to prevent torsional twist while the variable air cushions absorb the 40 mm stroke impact.
Vertical Dampened Lowering
Lowers a 15 kg packaging flap smoothly against gravity, using the needle cushions to soften the end-of-stroke drop while requiring an external check valve to hold the load safely.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X40 the Right Cylinder?
When sizing a double-rod cushioned cylinder, compare the real bidirectional thrust: the MFCD25 provides 206.1 N at 0.5 MPa, this MFCD32X40 delivers 345.6 N, and the larger MFCD40 offers 527.8 N. Choose the 32 mm bore when your high-speed twin-tool or anti-rotation load requires a safe working load around 207 N (about 60 percent of the 0.5 MPa figure) in both directions. The needle air cushions are ideal for soaking up kinetic energy at stroke ends, but remember they only decelerate the piston and never act as a brake or lock.
Mounting options include LB foot, FA flange, and TC trunnion brackets, with no SDB or back-cover code available because a rod exits both ends. This specific SKU lacks the internal magnet and cannot accept position sensors; if you need CMSG, DMSG, or EMSG switches, select the -S magnet variant instead.
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 MFCD32X40 FAQ
The MFCD32X40 is a double-acting, double-rod cylinder with equal force both ways (rod-side area). It generates 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical maximum of 70.5 kgf at 1.0 MPa. The air port is 1/4".
No. The variable air cushions only decelerate the piston near the stroke ends and do not lock or hold the load on air loss; use an external rod lock or pilot check valve for holding. Additionally, this SKU has no magnet (-S), so it cannot accept CMSG, DMSG, or EMSG switches.
