Airtac MF32-40 Stainless Steel Mini Cylinder MF40X280SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X280SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 280mm 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 MF40X280SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore JIS-standard round-body mini cylinder handles heavy-duty positioning within tight machinery envelopes. Because the SUS304 stainless barrel and riveted aluminium covers form a shorter physical body than an equivalent ISO 6432 unit, you reclaim valuable mounting length without sacrificing the 280 mm stroke. The structure naturally resists mild corrosion and washdown environments.
Equipped with a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches, this CM round-end rear cover version also relies on fixed TPU bumper pads to decelerate the stroke end. For practical actuation tasks, plan for roughly 377 N of usable work at 0.5 MPa, which translates to lifting about 32 kg vertically with a safe 2:1 margin. Air connects via a 1/4" port, and the 16 mm rod uses an M14x1.5 male thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X280SCM Is Used
Pallet Diverting Gate
Actuates a heavy routing flap on a packaging conveyor, using the 628.3 N thrust to push loaded pallets onto a secondary track without stalling.
Press Ram Positioning
Drives a small assembly press down 280 mm to seat bearings, where the fixed TPU bumpers absorb the repetitive end-of-stroke impact.
Vertical Carton Lift
Raises corrugated cartons in a distribution hub, safely lifting approximately 32 kg loads thanks to the robust 40 mm bore output.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X280SCM the Right Cylinder?
When sizing this 40 mm bore unit against the family, dropping down to the MF32 reduces the push force to 402.2 N at 0.5 MPa, while the MF40 represents the maximum standard thrust available in the series. If your fixture demands vertical holding when air pressure drops or a valve centres, remember this cylinder will drift; the TPU bumpers only soften the end-of-stroke impact and act as neither a brake nor a lock. You must integrate an external pilot-operated check valve or rod lock for suspended loads.
This specific SKU includes the -S magnet required for electronic or reed sensor tracking and features a CM round-end back cover suitable for clevis or pivot mounting arrangements. At a 280 mm stroke, carefully manage any lateral side loads to prevent rod bending and premature seal wear, favouring FA flange or LB foot mounts to maintain strict linear alignment.
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 MF40X280SCM FAQ
This 40 mm bore double-acting cylinder pushes with 628.3 N and pulls with 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 uses a 1/4" air port and an M14x1.5 male rod thread.
While it does not conform to ISO 6432 standards, the JIS-standard round-body design is intentionally shorter than an ISO 6432 cylinder for the same bore and stroke, saving space. It uses a CM round-end back cover for pivot mounting. Because this model includes the -S magnet, it fully supports CMSG, DMSG, and EMSG switches.
