Airtac MF32-40 Stainless Steel Mini Cylinder MF40X260SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X260SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 260mm 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 MF40X260SUTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty automation tasks. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Because the MF body is physically shorter than a comparable ISO 6432 cylinder at the same 40 mm bore and 260 mm stroke, it saves valuable mounting length in tight machinery.
The integrated magnet (-S) supports CMSG, DMSG, and EMSG position switches for end-of-stroke confirmation. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact by decelerating the piston. Plan for a safe working load of roughly 377 N, which means this actuator can comfortably lift about 32 kg vertically with a 2:1 safety margin. Air connects via a 1/4" port, and the U flat-end back cover pairs with a TC trunnion mount.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X260SUTC Is Used
Pallet Diverting Gate
Actuates a heavy diverting arm on a packaging conveyor, using the 628.3 N push force to reliably pivot loaded pallets onto a secondary track at high cycling speeds.
Press Fit Subassembly
Drives a small bearing into an aluminium housing on an automated assembly line, where the 32 kg vertical lift capacity provides consistent downward seating pressure.
Carton Flap Folder
Folds heavy cardboard flaps on a case erector, taking advantage of the compact JIS body length to fit within the tight mechanical clearances of the sealing head.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X260SUTC the Right Cylinder?
When sizing this 40 mm bore actuator, compare it directly against its neighbours: the smaller MF32 provides 402.2 N of push at 0.5 MPa, while the MF40 is the largest available in the series, pushing 628.3 N at the same pressure. If your fixture demands maximum thrust within a compact envelope, this model is the top choice. Keep in mind that a plain double-acting cylinder drifts when air is lost or the valve is centred; the bumpers only decelerate the stroke end and do not function as a brake. To hold a vertical load securely, add an external rod lock or a pilot-operated check valve.
The 260 mm stroke operates efficiently within the 30-800 mm/s speed range, but at this length you must carefully manage side loads to prevent rod bending. The TC trunnion mount helps absorb minor misalignment along the stroke. Furthermore, the -S magnet enables CMSG, DMSG, or EMSG sensors for precise position feedback, and the male M14x1.5 rod thread ensures robust load coupling.
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 MF40X260SUTC FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. At 0.5 MPa it delivers 628.3 N of push force and 527.8 N of pull force. 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.
The U flat-end back cover provides a standard rear interface, while the TC trunnion mount allows the cylinder body to pivot slightly during operation, which helps absorb rod misalignment on the 260 mm stroke. The fixed TPU bumper pads decelerate the piston at stroke ends, and the -S magnet allows CMSG, DMSG, or EMSG sensors to track position.
