Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MF32X450SCM
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting actuator handles substantial work. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder, it saves valuable mounting length on a 450 mm stroke. The SUS304 stainless barrel and riveted aluminium covers shrug off mild washdown while the piston's two-way seal retains an oil film for long service life.
Equipped from the factory with a piston magnet (-S) and a CM round-end back cover, it accepts CMSG, DMSG, or EMSG reed and electronic switches. Plan for about 241 N of actual work at 0.5 MPa, which translates to lifting roughly 20.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact, decelerating the load without adjustable cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCM Is Used
Carton Flap Folding
Extends 450 mm to fold large corrugated box flaps on a packing line, using its 402.2 N push rating to overcome board stiffness.
Vertical Parts Lift
Raises lightweight alloy trays between conveyor tiers; the magnetic piston allows DMSG sensors to confirm the top and bottom positions.
Film Roll Push-Off
Ejects finished shrink-wrap rolls from a winding mandrel, where the SUS304 barrel resists ambient humidity and cutting debris.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 drops the 0.5 MPa push force to 245.3 N, while stepping up to the MF40 increases it to 628.3 N. The 1/4" port and M10x1.25 male rod thread are fixed by the bore. At 450 mm of travel, keep the load guided to prevent rod bending and side-load wear.
If your process drops air or the valve centres, the piston will drift; the bumpers only soften the end of stroke and act as neither a lock nor a brake. To suspend a vertical load securely, add 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 MF32X450SCM FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. For deceleration, it relies on fixed TPU bumper pads rather than an adjustable air cushion; if you need adjustable cushioning for high speeds, look at the MFC variant.
