Airtac MF32-40 Stainless Steel Mini Cylinder MF40X65SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X65SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 65mm 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 MF40X65SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers that resist mild washdown. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 65 mm stroke, it drops right into tight machine envelopes without sacrificing power. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU pads and a front-cover anti-impact pad absorb stroke-end shock. This specific SKU includes a built-in magnet for position sensing and uses a 1/4" port with an M14x1.5 male rod thread.
For real-world sizing, plan your payload around a safe working load of roughly 377 N, which leaves a sensible margin below the 0.5 MPa rating. In vertical lift scenarios, that same 628.3 N output translates to lifting about 32 kg safely when you apply a 2:1 factor. The rear CA pivot cover simplifies articulated rod-end mounting, and the integrated magnet (-S) supports CMSG, DMSG, or EMSG reed and electronic switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X65SCA Is Used
Stamping Pin Ejection
Uses the 628.3 N push force at 0.5 MPa to knock stamped metal pins cleanly out of a progressive die, where the shorter JIS body prevents collision with the press ram.
Heavy Package Diverter
Swings a heavy-duty diverter arm on a logistics line to sort dense parcels, relying on the rear CA pivot to handle the articulated swing arc.
Pallet Lift Gate
Actuates a 32 kg mechanical lift gate on a packaging palletizer, safely moving the load within the 2:1 vertical lift margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X65SCA the Right Cylinder?
When sizing this 40 mm bore, compare it directly against its neighbours: the 32 mm MF generates 402.2 N of push at 0.5 MPa, while the 40 mm bore here provides 628.3 N. Since 40 mm is the largest standard MF diameter, moving beyond this force class requires a different cylinder family entirely. If your payload experiences sudden air loss or the directional valve is centred, the piston will drift—a standard MF cannot hold position unaided, so you should specify an external rod lock or a pilot-operated check valve for suspended loads. The fixed TPU bumper pads only decelerate the impact at the stroke end; they do not function as an adjustable air cushion (look to the MFC variant for that feature). For this 65 mm stroke, side-load and rod-bending stress are minimal, but always ensure the front clevis aligns with the CA pivot to prevent binding.
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 MF40X65SCA FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. At 0.7 MPa, the push increases to 879.6 N and the pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
Yes, the -S in the model code indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG electronic switches directly to the barrel. It does not have an adjustable air cushion; instead, it uses fixed TPU bumper pads to decelerate the stroke end. The SUS304 stainless construction also provides excellent mild corrosion resistance.
