Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MF40X200U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty automation with ease. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the piston's two-way seal retains an oil film for long service life. A fixed anti-impact pad on the front cover pairs with TPU bumper pads to decelerate the stroke end.
Because the MF body is physically shorter than an ISO 6432 cylinder for the same 40 mm bore and 200 mm stroke, it saves valuable mounting length in tight machinery. Plan for a real work rate of about 377 N, or roughly 60 percent of the 0.5 MPa rating. For vertical lifts, this translates to safely hoisting about 32 kg when applying a 2:1 safety margin. The unit features a 1/4 inch port and a U flat-end back cover, but because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200U Is Used
Pallet Diverting Gate
Uses the 628.3 N push force at 0.5 MPa to positively redirect heavy timber pallets onto a secondary packaging line without stalling.
Press Fit Bushing Station
Leverages the 200 mm stroke to drive bronze bushings deep into automotive gearbox housings, relying on the U flat-end cover for stable rear mounting.
Heavy Carton Flap Folder
Employs the compact JIS round-body length to fit within narrow sealing machine frames, folding thick corrugated cardboard flaps prior to tape application.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200U the Right Cylinder?
When sizing this 40 mm bore, compare it directly against the smaller MF32, which provides 402.2 N of push at 0.5 MPa. If your application demands less force, the 32 mm option saves space, but if you need the full 628.3 N output, this bore is the maximum available in the MF family. Keep in mind that a plain double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only soften the stroke end and will not function as a brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve.
This 200 mm stroke operates within the 500 mm standard limit, but at extended lengths you must carefully manage side loads to prevent rod bending. You can mount this unit using LB foot, FA flange, SDB pivot, or TC trunnion hardware. If your cycle requires adjustable end-deceleration for high speeds, consider the MFC variant instead of the fixed bumper design found here.
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 MF40X200U 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, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, its JIS-standard round body is shorter than an ISO 6432 cylinder, which helps conserve mounting length in tight fixtures.
