Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SCMTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SCMTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MF40X75SCMTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning in tight spaces. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 75 mm stroke, it saves valuable mounting length.
It features a 1/4" port, an M14x1.5 male rod thread, and fixed TPU bumper pads that soften stroke-end impact without offering adjustable cushioning. Equipped with a piston magnet (-S), it supports CMSG, DMSG, and EMSG sensors. Plan for roughly 377 N of actual work at 0.5 MPa, which means it can safely lift about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SCMTC Is Used
Clamp Actuation
Secures heavy automotive castings during CNC machining, using the 628.3 N push force to lock parts firmly against locators.
Pallet Diverter
Pushes loaded pallets onto secondary conveyor lines in distribution hubs, where the compact JIS body fits within tight transfer gaps.
Flap Folding
Folds heavy corrugated carton flaps prior to sealing, relying on the fixed TPU bumper pads to absorb the impact at the end of the 75 mm stroke.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SCMTC the Right Cylinder?
If 402.2 N from the MF32 is insufficient for your fixture, this 40 mm bore provides the necessary step up, representing the largest standard MF size available. For applications requiring a held load during air loss or valve centering, note that the bumper pads only decelerate the stroke end and act as neither a lock nor a brake; you will need an external rod lock or pilot-operated check valve.
This unit includes a CM round-end back cover and a TC trunnion mount, accommodating pivoting frameworks. The integrated -S magnet enables solid-state position sensing. At a 75 mm stroke, side-load and rod-bending stresses remain moderate, but ensure the front-cover anti-impact pad aligns properly with your load to maximize seal life.
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 MF40X75SCMTC FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
The CM round-end back cover paired with the TC trunnion mount allows the cylinder to pivot smoothly on a center axis, ideal for articulated mechanisms. The riveted SUS304 stainless build is shorter than a comparable ISO 6432 unit, and the built-in -S magnet supports CMSG, DMSG, and EMSG sensors.
