Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 450mm 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 MF40X450CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial workloads across its 450 mm travel. Because the SUS304 stainless barrel and riveted aluminium covers form a shorter body than an equivalent ISO 6432 unit, you save valuable mounting length on longer strokes. The structure uses fixed TPU bumper pads to decelerate the stroke end, while the piston relies on a two-way oil-retaining seal for extended lifespan.
Plan for a safe working load of roughly 377 N, which is about 60% of the 0.5 MPa rating, to ensure reliable operation. Alternatively, it can lift a 32 kg part vertically when applying a 2:1 safety margin to the 64 kgf available. This specific SKU lacks the internal magnet, meaning it cannot host CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection. Air connects via the 1/4" port, and the rear features a CM round-end cover.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CM Is Used
Pallet Divertor
Pushes heavy wooden pallets sideways onto a secondary packaging line using the full 628.3 N push force at 0.5 MPa across a 450 mm span.
Vertical Parts Lift
Raises 30 kg tote bins between conveyor tiers, staying safely within the 32 kg vertical lift capacity calculated with a 2:1 safety margin.
Gate Actuation
Opens and closes large machine guarding doors on automated assembly stations, benefiting from the compact JIS body length to fit tight cell perimeters.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CM the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task only requires 402.2 N of push at 0.5 MPa, as the MF series does not offer a larger standard bore. For this 450 mm travel, which approaches the 500 mm standard limit, minimizing side loading is critical to prevent rod bending—ensure the load travels on its own linear guides rather than cantilevering off the piston. You can mount the body using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions.
Remember that a standard cylinder drifts when air is removed or the valve centres; the TPU bumpers only soften the end-of-stroke impact and do not function as a braking lock. If your application must hold a vertical load statically, install an external pilot-operated check valve or a dedicated rod lock. Furthermore, because this model lacks the -S magnet, it cannot accept position switches.
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 MF40X450CM FAQ
This 40 mm bore cylinder features a 1/4" air 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.
This specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must specify the -S variant for sensing. It is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 cylinder for the same 40 mm bore and 450 mm stroke, saving mounting space without claiming ISO compliance.
