Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X500S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X500S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 500mm 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 MFCD40X500S
Twin rods exit both covers on this double-acting mini cylinder, yielding equal thrust in both directions while steadying the load against rotation. The MFCD40X500S generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa each way, with a theoretical maximum of 107.6 kgf at 1.0 MPa. Needle-set variable air cushions at both ends soak up high-speed end-of-stroke shock for smooth, quiet motion. The 500 mm stroke on this unit exceeds the 300 mm standard maximum, making it a non-standard, made-to-order item.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, the body is intentionally shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. It features a 1/4" port and M14x1.5 male rod threads. Because the -S option is present, a built-in piston magnet allows CMSG, DMSG, or EMSG switches to track position. The cushion only decelerates the load near the stroke end; it is not a lock or brake, so the piston will drift on air loss unless you fit an external rod lock or pilot check valve.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X500S Is Used
Twin-Tool Transfer
Drives a dual pick-and-place mechanism where the second rod mounts a parallel gripper, utilizing the 527.8 N both-ways thrust to shift heavy machined parts rapidly without rotational play.
High-Speed Lowering Press
Pushes a light stamping head downward at high speed while the needle-set air cushions absorb the end-of-stroke impact, protecting the fixture and ensuring smooth deceleration.
Extended-Stroke Divertor
Sweeps products across a wide 500 mm conveyor path, relying on the equal bidirectional force and SUS304 stainless construction to withstand mild washdown environments.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X500S the Right Cylinder?
When sizing these cylinders, compare the real thrust: this 40 mm bore delivers 527.8 N at 0.5 MPa both ways, whereas the smaller MFCD32 provides 345.6 N at the same pressure. Choose the 40 mm bore when moving heavier jigs or needing higher rigidity. The twin rods and adjustable air cushions excel in high-speed anti-rotation tasks and twin-tool setups where end-shock would otherwise damage the assembly. For vertical lifts, expect a safe working load of about 317 N (roughly 60% of the 0.5 MPa figure), which translates to handling about 26.9 kg each way with a 2:1 safety margin.
Mounting options include LB foot, FA flange, and TC trunnion styles; there is no SDB mount or back-cover code because a rod exits both ends. This specific 500 mm stroke is non-standard and made-to-order beyond the 300 mm catalog maximum. The included -S magnet supports CMSG, DMSG, and EMSG sensors for position feedback.
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 MFCD40X500S FAQ
It provides equal force both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical max of 107.6 kgf at 1.0 MPa. The air port is 1/4". Note that the 500 mm stroke is non-standard and made-to-order, exceeding the 300 mm standard maximum.
The twin rods resist rotation and provide equal thrust both ways, while the needle-set variable air cushions at both ends decelerate the piston to absorb high-speed shock. The cushion is not a lock or brake; the cylinder will drift on air loss, so use an external rod lock or pilot check valve for position holding. The -S magnet allows CMSG, DMSG, or EMSG switches for sensing.
