Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 450mm 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 MF40X450SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty automation within a compact footprint. Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 450 mm stroke, it saves valuable mounting length in tight machinery. The 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 life.
The fixed TPU bumper pads and front-cover anti-impact pad soften stroke-end impacts without offering adjustable cushioning. Plan for about 377 N of real work at 0.5 MPa, which means it can safely lift a 32 kg part vertically with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches, and the CM round-end back cover simplifies rear pivot mounting.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450SCM Is Used
Pallet Diversion
Pushes heavy timber pallets sideways off a main packaging line using 628.3 N of thrust at 0.5 MPa.
Press Feed Lowering
Lowers sheet metal blanks into a stamping press, safely managing a 32 kg vertical load with a 2:1 margin.
Container Lid Actuation
Pivots heavy industrial bulk container lids using the CM round-end rear cover for stable rear hinging.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450SCM the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which provides 402.2 N. Since 40 mm is the largest available MF bore, moving beyond this capacity requires a different cylinder family. For this 450 mm stroke, ensure your mounting method—such as LB foot, FA flange, or TC trunnion—adequately supports the rod against side loads to prevent bending.
Remember that a standard cylinder drifts when air is lost or the valve is centred; the bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MF40X450SCM FAQ
This 40 mm bore cylinder features a 1/4" air 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.
No, the base MF uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for variable cushioning look at the MFC variant. However, the -S suffix means this model has a built-in magnet for CMSG, DMSG, or EMSG switches.
