Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SCASDB
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SCASDB is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MF40X150SCASDB
Delivering 628.3 N of push force at 0.5 MPa, this double-acting AirTAC MF40X150SCASDB mini cylinder handles heavy-duty positioning tasks with ease. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 40 mm bore and 150 mm stroke, it saves valuable mounting length in tight machinery. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the internal two-way seal retains an oil film for extended mechanical life.
This specific SKU includes a built-in piston magnet for CMSG, DMSG, or EMSG switches, along with a CA pivot back cover and an SDB pivot-block mounting accessory. The 1/4" port feeds the 16 mm rod, and fixed TPU bumper pads absorb the end-of-stroke impact. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which means it can comfortably lift a 32 kg part vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SCASDB Is Used
Stamping Press Feed
Pushes heavy metal blanks into a stamping die, using the 628.3 N thrust to overcome material friction in a compact sub-assembly.
Pallet Diverter Arm
Actuates a pivot arm to redirect loaded pallets on a conveyor line, relying on the SDB mount to handle the shifting side loads.
Heavy Carton Lid Press
Holds corrugated carton flaps closed during adhesive application, where the 150 mm stroke provides the necessary reach.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150SCASDB the Right Cylinder?
When sizing this 40 mm bore unit, consider the neighbouring MF32, which provides 402.2 N of push at 0.5 MPa if your payload is lighter; since 40 mm is the largest available MF bore, moving beyond this capacity requires a different cylinder family entirely. The included SDB pivot-block pairs with the CA rear cover to accommodate angular misalignment during extension. If your application must maintain vertical position during a sudden air loss or valve centering, be aware that the piston will drift. The fixed bumpers only decelerate the stroke end and act as neither a lock nor a brake, so you must integrate an external rod lock or pilot-operated check valve to hold the load safely.
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 MF40X150SCASDB FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod. 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.
Yes, the -S suffix denotes an integrated magnet compatible with CMSG, DMSG, and EMSG switches. Additionally, its JIS-standard round-body design is inherently shorter than an ISO 6432 cylinder of the same bore and stroke, offering a packaging advantage without conforming to ISO 6432.
