Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X175S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X175S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MFCD40X175S
Twin rods exit both covers on this JIS-standard round-body mini cylinder, yielding equal 527.8 N thrust in both directions at 0.5 MPa while steadying the load against rotation. The SUS304 stainless barrel and riveted aluminium covers form a compact riveted body that is physically shorter than an ISO 6432 unit of identical bore and stroke, saving valuable machine space while resisting mild washdown corrosion.
A needle-set variable air cushion at each end absorbs high-speed end-of-stroke shock across the 175 mm travel, operating at 30-800 mm/s. Because this SKU includes the -S magnet, it directly accepts CMSG, DMSG or EMSG switches for position sensing. The 1/4 inch port feeds the 40 mm bore, which generates a safe working load of about 317 N or a 26.9 kg vertical lift with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X175S Is Used
Twin-Tool Transfer
Drives a high-speed pick-and-place head with tools mounted on both rod ends, using the 527.8 N force and twin rods to prevent rotation during rapid transfers.
Load Diverter Gate
Actuates a heavy diverter flap across a packaging line, relying on the variable air cushions to softly stop the 175 mm stroke at 800 mm/s without slamming.
Vertical Lift Stopper
Raises and lowers a 26 kg workpiece stopper on a warehouse conveyor, benefiting from equal force both ways and CMSG sensors to confirm the up and down positions.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X175S the Right Cylinder?
Choose the MFCD40 over the smaller MFCD32 when you need more muscle: 527.8 N both ways at 0.5 MPa versus 345.6 N for the 32 mm bore. The adjustable air cushions and dual rods are ideal for high-speed twin-tool actuation where smooth deceleration and anti-rotation are critical. Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover code exists since a rod exits both ends).
Remember that the air cushion only decelerates the piston near stroke end; it is not a brake. If air pressure drops, the piston will drift. For vertical or suspended loads that must hold position on air loss, install an external rod lock or pilot-operated check valve.
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 MFCD40X175S FAQ
It is a double-acting, double-rod cylinder with 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 40 mm bore uses a 1/4 inch port and an M14x1.5 male rod thread on the 16 mm rods.
The -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG sensors. 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. If air is lost, the piston drifts, so you need an external rod lock or pilot check valve for position holding.
