Airtac MF32-40 Stainless Steel Mini Cylinder MF32X130CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X130CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 130mm 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 MF32X130CM
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting mini cylinder is built around a JIS-standard round body. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments. Because the MF body is shorter than an ISO 6432 cylinder for the same 130 mm stroke, it saves valuable mounting length in tight machinery.
The internal piston relies on a two-way oil-retaining seal to maintain lubrication for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG reed switches without upgrading to the -S variant. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X130CM Is Used
Gate Diverters
Actuates routing flaps on packaging lines, using the 402.2 N push force to swing heavy aluminium gates reliably at 0.5 MPa.
Pallet Stops
Raises mechanical stop pins on roller conveyors to halt 20 kg workpiece pallets, benefiting from the compact JIS body length.
Carton Lid Presses
Folds corrugated carton flaps during case erecting, where the SUS304 barrel withstands dusty, mildly humid factory air.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X130CM the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 drops the 0.5 MPa push force to 245.3 N, whereas moving up to the MF40 increases it to 628.3 N. The CM round-end back cover suits rear pivot mounting, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion brackets. Air connects via the 1/4 inch port, and the male rod thread is M10x1.25.
Because this is a standard double-acting cylinder, the piston will drift and drop its load if air pressure is lost or the valve is centred—the TPU pads only decelerate the stroke end and act as no brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. At 130 mm, the stroke is well within standard limits, but ensure your front-end tooling is guided to prevent rod bending under 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 MF32X130CM FAQ
This 32 mm bore cylinder features a 1/4 inch port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion, and its JIS round body is intentionally shorter than an ISO 6432 cylinder to save mounting space.
