Airtac MF32-40 Stainless Steel Mini Cylinder MF40X130U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X130U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm 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 MF40X130U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning in tight fixtures. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way oil-retaining seal ensures long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 130 mm stroke, it saves valuable mounting length.
The fixed TPU bumper pads and front-cover anti-impact pad soften stroke-end impact by decelerating the piston, though they do not provide adjustable cushioning. Plan for about 377 N of real work at 0.5 MPa, which means it lifts roughly 32 kg vertically with a 2:1 safety margin. This specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors; it features a 1/4 inch port and a U flat-end rear cover.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X130U Is Used
Stamping Press Ejection
Uses the 628.3 N push force to knock stamped metal blanks out of a die, where the compact JIS body fits neatly inside the press frame.
Heavy Package Diversion
Pushes dense cartons off a main conveyor belt using the U flat-end rear cover for simple direct mounting.
Pallet Stopper Gate
Acts as a robust stop for loaded pallets on a roller conveyor, absorbing the impact via fixed TPU bumper pads.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X130U the Right Cylinder?
When sizing this 40 mm bore, check both neighbours: a 32 mm bore provides 402.2 N push at 0.5 MPa, while the 40 mm is the largest available in the MF series. If your fixture demands position holding on air loss, remember the piston will drift when the valve is centred—the bumpers only soften the end of stroke, so add an external rod lock or pilot-operated check valve for secured loads.
This non-magnetic version cannot accept a sensing switch, so order an -S variant if you require CMSG, DMSG, or EMSG sensors. You can mount it using LB foot, FA flange, SDB pivot, or TC trunnion brackets. With a 130 mm stroke, ensure the load is guided to prevent rod bending and side-load wear.
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 MF40X130U FAQ
This 40 mm bore cylinder features a 1/4 inch 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.
It does not conform to ISO 6432, although its JIS round-body is intentionally shorter than an ISO 6432 cylinder to save mounting length. Use LB, FA, SDB, or TC mounts. Also, this SKU lacks a magnet, so it cannot take a sensor; you need the -S version for CMSG, DMSG, or EMSG switches.
