Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CATC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CATC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 500mm 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 MF40X500CATC
Generating up to 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles the heaviest tasks in the MF range. It features a SUS304 stainless steel barrel with riveted aluminium covers, shrugging off mild corrosion and washdown environments. The piston relies on a two-way oil-retaining seal to maintain smooth lubrication over a long service life.
Because the stroke is 500 mm, this specific SKU is built as a non-standard, made-to-order length to maximize reach. For the same bore and stroke, the JIS-standard MF body is physically shorter than an ISO 6432 cylinder, saving valuable mounting length in tight machinery. Plan for a real working load of about 377 N, which lets you lift roughly 32 kg vertically with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread accommodate the high airflow needed for rapid cycling.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CATC Is Used
Pallet Diversion Arm
Swings a heavy diverter bar on a packaging line, using the 628.3 N thrust to push loaded pallets onto a secondary track.
Vertical Gate Actuator
Lifts a 30 kg access gate on an automated storage system, safely within the 32 kg vertical lift limit for reliable daily cycling.
Injection Mold Ejector
Drives a long-stroke ejection plate to clear large molded parts from a press, relying on the compact JIS body to fit tight tooling.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CATC the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task requires only 402.2 N of push at 0.5 MPa, as the 40 mm bore is the largest available in the MF series. For mounting, this configuration includes a CA pivot back cover and pairs with a TC trunnion accessory to handle the rotational alignment demands of a 500 mm stroke. Be mindful that extended rods are prone to bending under side loads, so guide the load externally.
This SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches. Furthermore, the fixed TPU bumper pads only soften the stroke-end impact; they do not act as a brake. If your application must hold a load vertically during air loss or valve centering, add an external rod lock or pilot check valve, as the piston will drift.
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 MF40X500CATC FAQ
The 40 mm bore provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and an M14x1.5 male rod thread.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. It features a CA pivot back cover and TC trunnion mounting, with fixed TPU bumpers that decelerate the stroke end but do not lock the load.
