Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 135mm 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 MF32X135SCM
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles robust mid-range automation tasks. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 135 mm stroke, it saves valuable mounting length in tight fixtures.
Equipped with a built-in piston magnet, this unit supports CMSG, DMSG, and EMSG position switches. Plan for roughly 241 N of actual work at 0.5 MPa, which means you can safely lift parts weighing about 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread provide solid pneumatic and mechanical interfaces. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts, decelerating the load without adjustable cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCM Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust, with the CM round-end cover allowing smooth pivot articulation.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, safely applying 241 N of working force to hold parts for milling operations.
Vertical Part Lifting
Elevates 20 kg component trays between conveyor tiers, relying on the compact JIS body length to fit within tight transfer cell clearances.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCM the Right Cylinder?
When sizing this 32 mm bore, compare its 402.2 N output against the MF25 at 245.3 N or the larger MF40 at 628.3 N to ensure optimal performance. The CM round-end rear cover suits pivot or clevis mounting arrangements, complemented by LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.
At 135 mm, the stroke is well within the 500 mm standard limit, though side loads should still be minimized to prevent rod bending. Remember that fixed TPU bumpers only decelerate the stroke end; they do not act as a brake. If your process must prevent drift on air loss or valve centering, add an external rod lock or pilot check valve to hold the payload securely.
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 MF32X135SCM FAQ
At 0.5 MPa it provides 402.2 N push and 345.6 N pull; at 0.7 MPa it yields 563 N push and 483.8 N pull, with a theoretical max of 82 kgf at 1.0 MPa. The bore-fixed air port is 1/4".
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake. For vertical loads, install an external rod lock or pilot check valve.
