Airtac MFD Double Rod Miniature Cylinder MFD40X175S
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD40X175S is a genuine double acting, double rod 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 MFD Double Rod Miniature Cylinder MFD40X175S
Twin rods exiting both covers give the AirTAC MFD40X175S equal force in both directions, generating 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers. Because it uses a rod-side area on both faces, the push and pull outputs are identical. The included -S magnet enables CMSG, DMSG or EMSG switches for position detection.
With a 40 mm bore, 1/4" port and M14x1.5 male rod threads, this unit handles a safe working load of about 317 N. That translates to a vertical lift capacity of roughly 26.9 kg each way with a 2:1 safety margin. For the same bore and stroke, this compact riveted body is shorter than an ISO 6432 cylinder, saving valuable mounting length while resisting mild corrosion and washdowns.

Where the Airtac MFD Double Rod Miniature Cylinder MFD40X175S Is Used
Anti-Rotation Slides
The twin rods steady the load and cut side-play, guiding heavy 40 mm bore tooling with 527.8 N of equal force during precise machining slides.
Twin-Tool Actuation
Mount a secondary stopper or clamp on the rear rod to operate a second station, utilising the identical push and pull output for synchronized tasks.
Back-Rod Switching
Use the -S magnet with DMSG sensors on the extended back rod to trigger cycle changes without interfering with the primary 175 mm stroke work area.
Is the Airtac MFD Double Rod Miniature Cylinder MFD40X175S the Right Cylinder?
When sizing, compare this 40 mm bore delivering 527.8 N at 0.5 MPa against the smaller MFD32 at 345.6 N. Choose the larger bore when moving heavier jigs or overcoming substantial friction. The double-rod design is ideal when you need strict anti-rotation control, want to mount a second tool on the back rod, or need a steady guide for side loads.
This SKU includes the -S magnet for CMSG, DMSG or EMSG sensors. Mounting options include LB foot, FA flange and TC trunnion brackets. Note that fixed TPU bumper pads decelerate the stroke ends, but the cylinder will drift on air loss; use an external rod lock or pilot check valve for load holding.
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 MFD Double Rod Miniature Cylinder MFD40X175S FAQ
It delivers 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" port, M14x1.5 male rod threads, and operates at 30-800 mm/s.
The twin rods provide equal force both ways and resist rotation under load. This -S model includes a piston magnet for CMSG, DMSG or EMSG switches. Fixed TPU bumpers decelerate the stroke, but an external rod lock is needed to hold position on air loss.
