Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MF40X60U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight fixtures. Its SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. The U flat-end back cover provides a straightforward rear mounting face.
For practical sizing, plan for about 377 N of real work at 0.5 MPa, which safely lifts a 32 kg part vertically with a 2:1 margin. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact, decelerating the load without offering adjustable cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60U Is Used
Press Die Ejection
Ejects heavy stamped metal parts from a die using the full 628.3 N push force at 0.5 MPa, fitting into compact press tooling where a longer ISO 6432 body would clash.
Pallet Diverter
Diverts loaded pallets on a packaging line; the 60 mm stroke and U flat-end rear cover allow secure mounting against the conveyor frame for stable lateral pushing.
Carton Flap Folder
Folds heavy cardboard flaps on large shipping cartons, relying on the SUS304 stainless barrel to withstand dusty, humid warehouse environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60U the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push at 0.5 MPa against the smaller MF32, which yields 402.2 N. Since 40 mm is the largest available MF bore, moving up in force requires switching to a different cylinder family entirely. The 1/4" port and M14x1.5 male rod thread match the bore's standard mapping.
Without the -S suffix, this specific unit cannot support magnetic sensors. If a valve centres or air pressure drops, the piston drifts and cannot maintain a held load; the fixed bumpers only decelerate the stroke end rather than acting as a brake. For vertical or suspended loads, install an external pilot-operated check valve or a rod lock.
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 MF40X60U FAQ
This 40 mm bore double-acting cylinder features a 1/4" 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 of 128.1 kgf at 1.0 MPa.
The JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder, saving mounting length. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. Note that because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
