Airtac MFD Double Rod Miniature Cylinder MFD40X160S
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD40X160S is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFD40X160S
Twin rods exiting both covers give the AirTAC MFD40X160S equal force in both directions, delivering 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. As a JIS-standard round-body mini cylinder, it uses a SUS304 stainless barrel with riveted aluminium covers, offering a shorter overall length than an ISO 6432 unit for the same bore and stroke. The 1/4 inch port and M14x1.5 male rod thread support robust 40 mm bore setups.
With a 160 mm stroke and a built-in magnet (-S), this double-acting design resists rotation and accepts CMSG, DMSG, or EMSG switches. The fixed TPU bumper pads decelerate the stroke ends without acting as a lock. For vertical lifts, expect a safe working load of about 317 N, handling roughly 26.9 kg each way with a 2:1 margin.

Where the Airtac MFD Double Rod Miniature Cylinder MFD40X160S Is Used
Twin-Tool Transfer
Drive two grippers at once using both rod ends to push and pull a 160 mm stroke with 527.8 N of equal force.
Anti-Rotation Guide
The dual 16 mm rods steady side loads and prevent twisting on indexing slides where a single rod would bind.
Back-Rod Switching
Mount a DMSG sensor flag on the opposing rod end to confirm the 160 mm travel without cluttering the primary tool side.
Is the Airtac MFD Double Rod Miniature Cylinder MFD40X160S the Right Cylinder?
When sizing this 40 mm bore against the smaller MFD32, the MFD40X160S provides a higher 527.8 N output at 0.5 MPa versus 345.6 N. Choose this model when your application demands the twin-rod anti-rotation advantage or requires mounting a second tool and a sensor flag on the back rod. The included -S magnet enables solid state or reed sensing.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not hold the load. If air pressure drops, the piston drifts, so install an external rod lock or pilot check valve for suspended loads. Mounting options include LB foot, FA flange, or TC trunnion, as the double-rod build omits the SDB back-cover option.
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 MFD40X160S FAQ
The MFD40X160S delivers equal force in both directions: 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. It features a 1/4 inch air port and a 16 mm rod on each end.
It uses fixed TPU bumper pads to decelerate at the stroke ends, not an adjustable air cushion. The cylinder does not lock or hold the load on air loss; use an external rod lock or pilot check valve for suspended loads. The -S suffix means it has a magnet for CMSG, DMSG, or EMSG sensors.
