Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm 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 MF32X100SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X100SU is a JIS-standard round-body mini cylinder engineered for compact automation. Its SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the riveted rolling-packed structure keeps the overall body shorter than a comparable ISO 6432 unit, saving valuable mounting length in tight fixtures. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life. Because the 402.2 N rating leaves a margin, plan for about 241 N of real work at 0.5 MPa, which translates to lifting roughly 20.5 kg vertically with a 2:1 safety factor.
This double-acting 32 mm bore unit features a 100 mm stroke and a 1/4" air port. Fixed TPU bumper pads and a front-cover anti-impact pad work together to soften the stroke-end impact, though they decelerate rather than provide adjustable cushioning. The included -S piston magnet supports CMSG, DMSG, and EMSG reed or electronic switches for position sensing, and the U flat-end back cover provides a straightforward rear mounting face.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SU Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 402.2 N push force to smoothly redirect cartons weighing up to 20 kg at 0.5 MPa.
CNC Lathe Door Indexing
Opens and closes a sliding safety door on a CNC lathe, where the shorter JIS body saves axial length and the SUS304 barrel withstands cutting fluid washdown.
Pallet Stacking Pusher
Advances components into a stacking cradle at 100 mm stroke, relying on the built-in magnet to trigger a DMSG sensor for precise positioning.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SU the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the larger MF40 offers 628.3 N. If your fixture demands the higher 628.3 N force, step up to the 40 mm bore, but if 245.3 N is sufficient, the 25 mm bore saves even more space. Remember that a plain double-acting cylinder like this will drift and drop its load if air pressure is lost or the valve is centred; the TPU pads only soften the end of stroke and act as neither a brake nor a lock. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your circuit.
The MF32X100SU uses an M10x1.25 male rod thread and operates at speeds from 30-800 mm/s. With a 100 mm stroke, ensure your mounting arrangement—whether LB foot, FA flange, or TC trunnion—prevents excessive side loading to avoid 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 MF32X100SU FAQ
The MF32X100SU has a 32 mm bore and a 1/4" air port. At 0.5 MPa it provides 402.2 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not function as a brake. For vertical loads, you must use an external rod lock or pilot check valve. The U flat-end back cover and shorter-than-ISO-6432 JIS body simplify mounting in tight vertical spaces.
