Airtac MF32-40 Stainless Steel Mini Cylinder MF40X125UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X125UTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 125mm 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 MF40X125UTC
Generating 628.3 N of push force at 0.5 MPa, the AirTAC MF40X125UTC is a 40 mm bore double-acting mini cylinder built to JIS standards. Its SUS304 stainless steel round barrel and riveted aluminium covers form a compact body that is physically shorter than a comparable ISO 6432 unit, delivering a real packaging advantage for tight 125 mm stroke fixtures. The structure uses fixed TPU bumper pads and a front-cover anti-impact pad to decelerate the piston at stroke end.
Because the piston employs a heterogeneous two-way seal with an oil-reservoir function, it maintains a lubricating film for extended operational life. Plan for roughly 377 N of actual work at 0.5 MPa, which means this unit lifts about 32 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches; it features a 1/4 inch port and an M14x1.5 male rod thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X125UTC Is Used
Pallet Diverting Gate
Uses the 628.3 N push force to pivot heavy timber pallets onto a secondary packaging line without stalling under friction.
Press Pad Actuation
Drives a 125 mm stroke downward press head to seat bearings into housings, relying on the U flat-end cover for stable rear mounting.
Carton Flap Folder
Deploys the TC trunnion mount to swing a folding arm, tucking heavy cardboard flaps prior to tape sealing in high-speed logistics.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X125UTC the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your application only requires 402.2 N of push at 0.5 MPa, as the 40 mm bore is the largest available in the MF series. This model includes a U flat-end back cover and uses a TC trunnion mount, which accommodates pivoting movements along the cylinder axis. For long 125 mm strokes, minimize side-loading to prevent rod bending and premature seal wear.
Remember that fixed TPU bumpers only soften the end-of-stroke impact; they do not function as a braking mechanism. If air pressure drops or the valve is centred, the piston will drift, meaning an external rod lock or pilot-operated check valve is required to safely hold a suspended load.
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 MF40X125UTC FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male rod 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.
No, this specific SKU lacks the internal magnet required for switches. You must select an MF40 variant with the -S suffix to use CMSG, DMSG, or EMSG sensors. The SUS304 stainless body is shorter than ISO 6432 cylinders and uses fixed TPU bumper pads rather than adjustable cushions.
