Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X450S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X450S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 450mm 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 MFCD40X450S
Twin rods exiting both SUS304 stainless covers give this JIS-standard round-body mini cylinder equal 527.8 N force in each direction at 0.5 MPa, rising to 738.9 N at 0.7 MPa. The 450 mm stroke exceeds the 300 mm standard limit, making this specific SKU a non-standard, made-to-order item. Its riveted aluminium construction is shorter than an equivalent ISO 6432 cylinder, saving valuable machine space.
A needle-set variable air cushion at each end absorbs high-speed end-of-stroke shock, operating smoothly between 30-800 mm/s. The second rod steadies the load and resists rotation, while the included -S magnet enables CMSG, DMSG or EMSG switches for position sensing. Air connects via 1/4" ports (M14x1.5 male rod thread). The cushion decelerates the piston but does not lock it; for vertical loads, expect a safe working load around 317 N or a 2:1 margin lift of 26.9 kg.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X450S Is Used
Twin-Tool Transfer
Use the 527.8 N equal thrust and dual rods to shuttle heavy parts between stations at high speed without rotational play.
Elevating Carriage
Lift a 26.9 kg vertical load (2:1 safety margin) smoothly; the variable air cushions absorb the shock at the 450 mm stroke ends.
High-Speed Diverting
Push items across a belt with equal force both ways, relying on the 1/4" port and 30-800 mm/s speed range for rapid cycling.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X450S the Right Cylinder?
When sizing this double-acting family, compare the real thrust: the MFCD32 provides 345.6 N at 0.5 MPa, whereas this MFCD40 delivers 527.8 N both ways. Choose the 40 mm bore when moving heavier jigs or resisting high torque. The 450 mm stroke is non-standard, so confirm lead times for made-to-order runs.
The adjustable air cushions excel in high-speed, shock-sensitive setups, and the twin rods prevent twist during travel. Because a standard cylinder drifts on air loss, add an external rod lock or pilot check valve if you must hold a load mid-stroke. Mount using LB foot, FA flange or TC trunnion brackets (no SDB or back-cover code exists). The -S magnet supports CMSG, DMSG and EMSG sensors.
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 MFCD40X450S FAQ
It generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa equally in both directions, with a theoretical max of 107.6 kgf at 1.0 MPa. The bore uses a 1/4" air port.
No, the variable air cushion only decelerates near the stroke end; it is not a brake. The piston will drift on air loss, so use an external rod lock. The -S magnet allows CMSG, DMSG or EMSG switches.
