Airtac MF32-40 Stainless Steel Mini Cylinder MF40X470SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X470SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 470mm 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 MF40X470SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting AirTAC MF40X470SCA handles heavy-duty positioning within tight machine envelopes. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder for the same 40 mm bore and 470 mm stroke, it saves valuable mounting length without sacrificing power.
The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for long service life. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. With a practical working load of roughly 377 N, it can reliably lift about 32 kg vertically. The 1/4" port and M14x1.5 male rod thread accommodate robust plumbing, and the integrated magnet (-S) supports CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X470SCA Is Used
Pallet Diverting Gate
Uses the 628.3 N thrust to push heavy timber pallets onto a secondary packaging line, leveraging the 470 mm stroke to clear the main conveyor bed.
Press Tool Ejection
Retracts stamped metal parts from a die, relying on the CA pivot mount to absorb angular misalignment during the downward ejection cycle.
Carton Flap Folding
Deploys the long 470 mm stroke to fold large corrugated carton flaps, while the SUS304 barrel withstands occasional washdown in food packing zones.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X470SCA the Right Cylinder?
When sizing this 40 mm bore unit, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which yields 402.2 N under the same pressure. Since 40 mm is the largest available MF bore, exceeding this capacity requires a different cylinder family. The CA rear pivot cover is ideal for clevis mounting, and you can pair it with LB foot, FA flange, or TC trunnion brackets.
Note that this standard cylinder will drift if air pressure is lost or the valve is centered; the TPU pads only decelerate the stroke end and do not function as a brake. For suspended loads, install an external rod lock or pilot check valve. Additionally, the 470 mm stroke demands careful alignment to prevent rod bending and premature seal wear from side loads.
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 MF40X470SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 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, with a theoretical maximum of 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and an M14x1.5 male rod thread.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG reed or electronic switches directly to the barrel. However, the cylinder does not hold its load if air is lost; the fixed TPU bumpers only decelerate the stroke end, so use a pilot check valve for suspended loads.
