Airtac MF32-40 Stainless Steel Mini Cylinder MF40X750SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X750SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 750mm 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 MF40X750SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning tasks. The 750 mm stroke exceeds the 500 mm standard limit, making it a made-to-order unit engineered for long-reach actuation. Its SUS304 stainless barrel and riveted rolling-packed aluminium covers naturally resist mild corrosion and washdown environments. Inside, a two-way seal retains an oil film for extended mechanical life, while fixed TPU bumper pads soften the stroke-end impact.
Because the MF body is physically shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length on long-travel machinery. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG position switches. For real-world sizing, plan for a safe working load of roughly 377 N (about 60% of the 0.5 MPa rating), which means it can vertically lift approximately 32 kg with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X750SCM Is Used
Pallet Transfer Diversion
Uses the 628.3 N push force at 0.5 MPa to deflect heavy wooden pallets onto secondary packaging lines without stalling.
Long-Reach Press Unloading
Extends the full 750 mm made-to-order stroke to extract stamped metal parts from deep hydraulic press beds safely.
High-Bay Tray Handling
Leverages the compact JIS body length to push loaded product trays into tight high-density storage racking systems.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X750SCM the Right Cylinder?
When sizing this 40 mm bore unit, compare it directly against the neighbouring MF32, which provides 402.2 N of push at 0.5 MPa. If the 32 mm variant lacks the necessary thrust for your fixture, stepping up to this 40 mm bore yields a significant jump to 628.3 N. Since 40 mm is the largest available MF bore, exceeding this force class requires migrating to an entirely different cylinder series. The CM round-end back cover provides a specific pivot interface, and the 1/4" port matches the 40 mm bore standard.
At a 750 mm stroke, this made-to-order cylinder is highly susceptible to side loads and rod bending, so ensure your mounting method—whether LB foot, FA flange, SDB pivot, or TC trunnion—perfectly aligns the load to prevent premature seal wear. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred; the TPU bumpers only decelerate the end of travel and do not function as a braking lock. To suspend a load safely during an air loss event, 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 MF40X750SCM FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. The thrust ratings are 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the directional valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. To maintain a vertical position during an air failure, you must install an external rod lock or a pilot-operated check valve.
