Airtac MF32-40 Stainless Steel Mini Cylinder MF40X350SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X350SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 350mm 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 MF40X350SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers. The MF40X350SCA includes a piston magnet for position sensing and features a CA pivot back cover for clevis mounting. A two-way oil-retaining seal lubricates the bore for extended cycle life.
Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit at the same 350 mm stroke, it saves valuable mounting length in tight machinery. Fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Plan for roughly 377 N of actual work at 0.5 MPa, which means it can safely lift about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X350SCA Is Used
Pallet Dispenser Pusher
Uses the 628.3 N thrust at 0.5 MPa to strip empty pallets from a magazine stack, leveraging the CA pivot to accommodate slight angular misalignment.
Heavy Package Diverter
Swing-arm diverter on a packaging line relying on the 350 mm stroke to redirect heavy cartons, with the DMSG switch confirming the extended position.
Press Ejector Station
Ejects formed metal blanks from a die bed, taking advantage of the SUS304 construction to resist mild washdown and cutting fluid splashes.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X350SCA the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task only needs 402.2 N of push at 0.5 MPa, as the 40 mm is the largest available MF bore. The integrated -S magnet allows direct mounting of CMSG, DMSG, or EMSG electronic switches. The CA rear pivot cover suits articulated rod-end loads.
Be aware that a standard cylinder drifts if air pressure drops or the valve centers; the internal bumpers only decelerate the stroke end and will not lock the load. Install an external pilot check valve or rod lock if you need fail-safe holding. At 350 mm of travel, verify your rod-end alignment to prevent side-loading and premature seal wear.
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 MF40X350SCA 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. The air port is 1/4" and the male rod thread is M14x1.5.
No, the base MF uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for variable cushioning look at the MFC variant. It is a JIS-standard round body that is shorter than an ISO 6432 cylinder, but it does not conform to the ISO 6432 standard.
