Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150CM 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 MF40X150CM
Generating 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy-duty positioning within tight machine envelopes. Because the JIS-standard riveted round body is physically shorter than a comparable ISO 6432 unit for the same 150 mm stroke, it directly saves valuable mounting length. The SUS304 stainless barrel and aluminium covers are joined by a rolling-packed structure that shrugs off mild washdown, while the internal two-way seal retains an oil film for extended cycle life.
This specific CM round-end configuration uses a 1/4" air port and an M14x1.5 male rod thread. It provides a practical vertical lift capacity of about 32 kg when you apply a 2:1 safety margin to the 0.5 MPa output, allowing you to confidently match real part weights. Fixed TPU bumper pads and a front-cover anti-impact pad work together to soften the end-of-stroke impact, reliably decelerating the load without the need for adjustable cushioning. Note that this SKU lacks a magnet and therefore cannot support position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150CM Is Used
Stamping Press Ejection
Uses the 628.3 N push force to knock heavy stamped metal parts out of a die, where the shorter JIS body prevents interference with the press tooling.
Pallet Diverting Arm
Swings a deflector plate via the CM round-end pivot to reroute heavy packaging pallets, relying on the 32 kg vertical lift margin to overcome guide friction.
Vertical Carton Lid Flap
Closes heavy cardboard carton lids on a packing line, with the fixed TPU bumper pads absorbing the impact when the lid snaps shut at the end of the 150 mm stroke.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150CM the Right Cylinder?
When sizing this 40 mm bore unit, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which outputs 402.2 N. If your fixture requires even more power, remember that 40 mm is the largest available bore in the MF family, so you would need to gang multiple cylinders or change series entirely. The CM round-end back cover suits pivot-mount installations, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion brackets depending on your frame geometry.
Since this 150 mm stroke model has no -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches. Keep in mind that a standard double-acting cylinder will drift and drop its payload if air pressure is lost or the control valve is centred; the internal bumpers only soften the stroke end and will not act as a brake. To suspend a load safely during an emergency stop, integrate an external pilot-operated check valve or a dedicated rod lock.
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 MF40X150CM FAQ
At 0.5 MPa it provides 628.3 N push and 527.8 N pull. At 0.7 MPa it yields 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore model uses a 1/4" air port and a 16 mm rod with an M14x1.5 male thread.
No, the MF40X150CM lacks the -S suffix, meaning it has no internal piston magnet and cannot be fitted with CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The unit features a SUS304 stainless barrel and fixed TPU bumpers rather than adjustable air cushions.
