Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60SU 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 MF40X60SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning in tight spaces. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments. For the same 40 mm bore and 60 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, saving valuable mounting length. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften end-of-stroke impacts.
Because the SKU includes an S, a built-in piston magnet enables CMSG, DMSG or EMSG switches for position sensing. Plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. The 1/4 inch port feeds the 16 mm rod, and the U flat-end back cover mounts flush against machine frames.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60SU Is Used
Press-Fit Bushings
Drives small bearings into aluminium housings on an automated press line, utilizing the 628.3 N push force at 0.5 MPa to seat parts accurately.
Heavy Diverter Gate
Actuates a robust routing flap on a packaging conveyor, where the compact JIS body length fits within the tight 60 mm clearance between parallel belts.
Pallet Stopper Arm
Raises and lowers a solid stop block to halt loaded pallets, safely handling the 32 kg vertical lift capacity calculated with a 2:1 safety margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X60SU the Right Cylinder?
If 402.2 N at 0.5 MPa from the MF32 is insufficient for your fixture, this 40 mm bore provides the necessary step up in thrust. Since 40 mm is the largest standard MF bore, moving higher requires a different cylinder family. The fixed TPU bumpers decelerate the stroke end but do not function as a lock; if air pressure drops or the valve is centred, the piston will drift. For vertical loads that must be held securely, install an external rod lock or a pilot-operated check valve.
The U flat-end rear cover suits direct back-mounting against stationary plates. Position sensing requires the integrated magnet in this -S model to pair with CMSG, DMSG or EMSG switches. Even at a short 60 mm stroke, side loading should be minimized to prevent 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 MF40X60SU FAQ
The 40 mm bore yields a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It features a 1/4 inch air port and a 16 mm piston rod.
It features a SUS304 stainless steel round body that is shorter than a comparable ISO 6432 cylinder, saving mounting length. The U suffix denotes a flat-end back cover for direct mounting. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion.
