Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MF40X100SUTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty actuation within tight machine envelopes. For the same 40 mm bore and 100 mm stroke, the riveted SUS304 stainless steel barrel and aluminium covers create a body notably shorter than an ISO 6432 unit, saving valuable mounting length. The internal piston relies on a heterogeneous two-way seal that retains an oil film for prolonged lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad absorb end-of-stroke shocks.
Engineered for 1/4" pneumatic ports and a 16 mm rod with an M14x1.5 male thread, the unit operates between 0.15-1.0 MPa. Because the -S suffix equips the piston with a magnet, you can mount CMSG, DMSG, or EMSG sensors for position detection. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 32 kg vertically under a 2:1 safety factor.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SUTC Is Used
Pallet Diverting Gate
Uses the 628.3 N push force to swing heavy diverting arms on a packaging conveyor, shifting loaded pallets onto secondary routing lines.
Stamping Press Feed
Pushes raw metal blanks into a small stamping press, relying on the TC trunnion mount to absorb angular stress during the 100 mm extension.
Carton Flap Folder
Drives a mechanical folding arm to close heavy corrugated carton flaps, utilizing the built-in magnet to confirm flap closure via a DMSG sensor.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SUTC the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which yields 402.2 N. Since 40 mm is the largest available bore in the MF series, stepping up requires switching to an entirely different cylinder family. This SKU includes the U flat-end back cover and a TC trunnion mount, providing a pivoting centerline that accommodates slight misalignment.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not act as a brake. If air pressure drops or the valve centers, the piston will drift and drop the load. To secure a vertical load safely, integrate an external pilot-operated check valve or a dedicated rod lock rather than relying on the cylinder itself.
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 MF40X100SUTC FAQ
This 40 mm bore double-acting cylinder features a 1/4" port and generates 628.3 N push and 527.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only soften the impact at the stroke end and do not function as a locking brake. If air is lost, the piston will drift. You must use an external rod lock or pilot check valve to hold a suspended load. The -S magnet allows CMSG/DMSG/EMSG sensors to track position.
