Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75CMTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75CMTC 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 MF40X75CMTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight fixtures. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for extended lifespan. For the same 40 mm bore and 75 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, delivering a tangible packaging advantage.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end is softened but cannot be adjusted. Plan for roughly 377 N of real work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. This specific configuration features a CM round-end rear cover and a TC trunnion mount. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75CMTC Is Used
Press Fit Subassemblies
Drives a 32 kg bearing housing into a machined jig using the full 628.3 N thrust at 0.5 MPa.
Pallet Diverter Gate
Articulates a heavy sorting flap via the TC trunnion mount to redirect loaded pallets on a packaging line.
Vertical Lift Gate
Raises a 30 kg access door on a washdown station, relying on the SUS304 barrel to endure humid environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75CMTC the Right Cylinder?
When sizing this 40 mm bore, verify your actual load requirements against the available range. If the 628.3 N push at 0.5 MPa exceeds your needs, step down to the MF32 which provides 402.2 N; since 40 mm is the largest available MF bore, any requirement beyond 879.6 N at 0.7 MPa dictates moving to a larger series entirely. The 1/4" port and M14x1.5 male rod thread are fixed for this bore size.
The included TC trunnion and CM round-end back cover suit pivoting articulated assemblies. Remember that a standard cylinder drifts if air pressure drops or the valve is centred, as the TPU pads only decelerate the stroke end rather than locking the rod. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MF40X75CMTC 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 of 128.1 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so CMSG, DMSG, or EMSG switches cannot be used. You must select an MF40 model with the -S suffix to enable magnetic sensing.
