Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MF32-40 Stainless Steel Mini Cylinder MF32X100U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles demanding mid-range tasks. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended lifespan. Because the MF body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length in tight fixtures.
Equipped with a U flat-end back cover and fixed TPU bumper pads that soften stroke-end impact, it operates at 30-800 mm/s with a 1/4" port. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100U Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust, fitting neatly into tight conveyor transfer gaps.
Clamp Actuation
Secures aluminium extrusions during a machining cut, providing stable holding without exceeding the 241 N safe working load.
Parts Ejection
Kicks finished moulded components out of a press die using the U flat-end cover to absorb the rear stroke impact.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100U the Right Cylinder?
When sizing this 32 mm bore, compare it directly with its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the MF40 steps up to 628.3 N. If your fixture demands position holding on air loss, remember that a plain cylinder drifts when the valve is centred—the TPU pads only decelerate the stroke end, so you must add an external rod lock or pilot check valve for secure load holding.
This model features a male M10x1.25 rod thread and a 100 mm stroke. For mounting, you can utilise LB foot, FA flange, SDB pivot, or TC trunnion brackets to suit your frame. If your application requires adjustable air cushioning for high-speed cycles, consider the MFC variant instead of the standard bumper design.
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 MF32-40 Stainless Steel Mini Cylinder MF32X100U FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG switches. The U flat-end back cover and fixed TPU bumpers are standard, and the JIS round-body design is physically shorter than an ISO 6432 cylinder.
