Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MF40X150SU
Generating 628.3 N of push force at 0.5 MPa, this double-acting AirTAC MF40X150SU is a JIS-standard round-body mini cylinder built around a SUS304 stainless barrel with riveted aluminium covers. The 40 mm bore pairs with a 1/4 inch port and a 16 mm rod to handle heavy-duty positioning tasks. Because the riveted rolling-packed structure is more compact, the overall body is physically shorter than an ISO 6432 cylinder of the exact same bore and stroke, delivering a tangible packaging advantage in tight machine fixtures.
The internal piston relies on a heterogeneous two-way seal that retains an oil film for sustained mechanical life, while fixed TPU bumper pads and a front-cover anti-impact pad work together to soften stroke-end impacts. Equipped with a built-in magnet (-S) and a flat-end U back cover, this unit supports CMSG, DMSG, and EMSG position sensing. For practical actuation at 0.5 MPa, plan for roughly 377 N of usable work, which translates to safely lifting about 32 kg vertically against gravity.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SU Is Used
Pallet Diverting Gate
Utilizes the 628.3 N push force to swing heavy diverter arms on packaging conveyors, routing dense cartons at high speed.
Press Pad Actuation
Drives a 150 mm downward stroke to lower a compacting head onto industrial gasket materials, relying on the flat-end U cover for stable base mounting.
Vacuum Lifter Alignment
Shifts heavy suction cup gantries into position over sheet metal, using the built-in -S magnet with DMSG switches to confirm extension.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SU the Right Cylinder?
If 402.2 N from the 32 mm bore variant is insufficient for your drive requirements, this 40 mm bore model steps up the output to 628.3 N at 0.5 MPa, representing the largest standard diameter available in the MF range. The integrated -S magnet allows seamless fitting of CMSG or DMSG reed switches for end-of-stroke confirmation, and the flat-end U back cover suits direct rear mounting arrangements.
Remember that fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a mechanical lock. If air pressure drops or the control valve is centred, the rod will drift and drop the load. To secure a vertical load safely, you must add an external pilot-operated check valve or a dedicated rod lock. Furthermore, at the 150 mm stroke length, watch out for side-loading forces to prevent rod bending 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 MF40X150SU FAQ
This 40 mm bore double-acting cylinder uses a 1/4 inch air port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
The JIS-standard riveted stainless-steel body is deliberately shorter than an ISO 6432 cylinder for the same 40 mm bore and 150 mm stroke, saving valuable mounting length. It relies on fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and the included -S magnet enables CMSG, DMSG, or EMSG sensor switches.
