Airtac MF32-40 Stainless Steel Mini Cylinder MF40X270SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X270SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 270mm 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 MF40X270SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting actuator tackles heavy automation tasks. The JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length in tight machine frames. It features a SUS304 stainless steel barrel with riveted aluminium covers, resisting mild corrosion and washdown environments.
The piston relies on a two-way oil-retaining seal for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Because the -S suffix denotes a built-in magnet, you can mount CMSG, DMSG, or EMSG switches for position sensing. Plan for roughly 377 N of actual work at 0.5 MPa, which means it lifts about 32 kg vertically with a 2:1 safety margin. Air connects via the 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X270SCA Is Used
Press Fit Subassembly
Drives a 270 mm stroke to press bearings into heavy housings, utilising the 628.3 N push force to seat components firmly.
Pallet Divertor Arm
Swings on its CA pivot to push heavy pallets off a main conveyor line, benefiting from the compact JIS body length.
Vertical Lift Gate
Raises a 30 kg material gate using the 32 kg safe vertical lift capacity, tracking position with CMSG sensors.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X270SCA the Right Cylinder?
If 402.2 N from the smaller MF32 bore is insufficient for your fixture, this 40 mm option provides the necessary step up in thrust without leaving the JIS mini cylinder family. Since 40 mm is the largest available MF bore, moving higher in force requires switching to an entirely different cylinder series.
This SKU includes a CA pivot back cover for articulated mounting and a piston magnet for sensors. Remember that the fixed TPU bumpers only decelerate the stroke end; they do not function as a brake. If your application must prevent drift on air loss or valve centring, install an external rod lock or a pilot-operated check valve.
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 MF40X270SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore model uses a 1/4" air port and an M14x1.5 male rod thread.
No, the base MF uses fixed TPU bumper pads that simply decelerate the piston at the stroke end. For adjustable air cushioning, you need the MFC variant. This model does include the -S magnet for CMSG/DMSG/EMSG sensors and a CA pivot back cover.
