Airtac MFD Double Rod Miniature Cylinder MFD32X250
The AirTAC Airtac MFD Double Rod Miniature Cylinder MFD32X250 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MFD32X250
Twin rods exiting both covers define the AirTAC MFD32X250, ensuring identical thrust in extend and retract directions via the rod-side area. This JIS-standard round-body mini cylinder uses a SUS304 stainless barrel with riveted aluminium covers, delivering 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa both ways. The 1/4" air port feeds a 32 mm bore that hits a theoretical maximum of 70.5 kgf at 1.0 MPa.
Because the second rod steadies the payload, side-play is significantly reduced compared to a single-rod build. The body is inherently shorter than an ISO 6432 cylinder for the same stroke, saving valuable mounting length. With a 0.5 MPa input, the safe working load is about 207 N, which translates to roughly 17.6 kg of vertical lift with a 2:1 safety margin. Fixed TPU bumper pads decelerate the stroke ends, while the lack of an -S suffix means this specific SKU cannot accept magnetic sensors.

Where the Airtac MFD Double Rod Miniature Cylinder MFD32X250 Is Used
Anti-Rotation Slides
The twin 12 mm rods resist twist during 250 mm traverses, keeping precision slides perfectly steady under a 207 N safe working load.
Twin-Tool Actuation
Mount a secondary gripper on the rear rod to operate a second station simultaneously, leveraging the equal 345.6 N force both ways.
Vertical Lift Guides
Lift approximately 17.6 kg vertically with a 2:1 safety margin; the dual rods prevent the load from binding or rotating on descent.
Is the Airtac MFD Double Rod Miniature Cylinder MFD32X250 the Right Cylinder?
When sizing this 32 mm bore against the family, the MFD25 yields 206.1 N at 0.5 MPa, whereas the MFD40 provides 527.8 N at 0.5 MPa. The MFD32X250 sits perfectly in the middle, offering 345.6 N both ways for applications needing moderate push and pull power over a 250 mm stroke. Choose the double-rod layout when you need strict anti-rotation guidance or want to mount a secondary tool on the back rod.
This non-magnet SKU cannot host CMSG, DMSG, or EMSG switches; add the -S option if sensing is required. Mounting options include LB foot, FA flange, and TC trunnion, with no SDB or back-cover code available. Remember that the TPU bumpers only decelerate the stroke end and do not function as a brake; if air pressure drops, the piston will drift. Use an external rod lock or pilot check valve to hold a suspended load safely.
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 MFD32X250 FAQ
The MFD32X250 delivers equal force in both directions because it is a double-rod cylinder using the rod-side area. It outputs 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical maximum of 70.5 kgf at 1.0 MPa. The 32 mm bore uses a 1/4" air port.
No, this specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an -S variant for position sensing. The twin rods provide anti-rotation guidance, but note that fixed TPU bumpers only decelerate the stroke end and will not hold the load if air pressure is lost.
