Airtac MFD Double Rod Miniature Cylinder MFD40X60
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD40X60 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MFD40X60
Twin rods exiting both covers give the AirTAC MFD40X60 equal thrust in both directions, making this JIS-standard round-body mini cylinder a natural fit for guided lifting and twin-tool actuation. The SUS304 stainless steel barrel shrinks mounting length compared to an ISO 6432 unit while resisting mild washdown corrosion, and the riveted aluminium covers keep the assembly light. Air connects via a 1/4 inch port, driving a 16 mm rod with an M14x1.5 male thread on each end.
At 0.5 MPa this 40 mm bore generates 527.8 N of force both ways, climbing to 738.9 N at 0.7 MPa. Because the second rod steadies the load and resists rotation, you can mount a stopper or secondary tool on the back side without adding a separate guide. This non-magnet SKU cannot host a position switch, but specifying the -S variant adds a magnet for CMSG, DMSG or EMSG sensors. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.

Where the Airtac MFD Double Rod Miniature Cylinder MFD40X60 Is Used
Guided Vertical Lift
Lifts roughly 26.9 kg vertically with a 2:1 safety margin at 0.5 MPa, using the twin rods to keep the load steady and prevent twisting during elevation.
Twin-Tool Actuator
Mounts a secondary gripper or stopper on the rear rod to operate a second stage simultaneously, capitalizing on the 527.8 N equal thrust in both directions.
Anti-Rotation Diverter
Diverts packages on a line without side-play, as the dual 16 mm rods resist rotational torque better than a single-rod mini cylinder.
Is the Airtac MFD Double Rod Miniature Cylinder MFD40X60 the Right Cylinder?
When sizing a double-rod mini, your two main options are this 40 mm bore and the MFD32. The MFD32 yields 345.6 N at 0.5 MPa, while the MFD40X60 delivers 527.8 N at the same pressure, giving you a safe working load of roughly 317 N or a vertical lift of about 26.9 kg with a 2:1 margin. Choose the 40 mm bore when you need that extra push and pull simultaneously.
The twin-rod design inherently resists rotation, but remember that a standard cylinder drifts if air pressure drops—the fixed TPU bumpers only soften the end of stroke, they do not lock the load. For vertical holding, plan to add an external rod lock or pilot check valve. You can mount this cylinder using LB foot, FA flange or TC trunnion brackets, but note that SDB and back-cover codes are unavailable because a rod exits the rear.
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 MFD40X60 FAQ
The MFD40X60 provides equal force in both directions because it is a double-rod cylinder using the rod-side area. It outputs 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and has a theoretical maximum of 107.6 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet and cannot host a sensing switch. You must select the -S variant to enable CMSG, DMSG or EMSG magnetic sensors. The twin-rod design still provides equal force and anti-rotation benefits without the sensor.
