Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200CM 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 MF40X200CM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X200CM is a robust 40 mm bore double-acting round-body cylinder built to JIS standards. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. The piston relies on a heterogeneous two-way seal that retains an oil film for extended lifespan, while a fixed anti-impact pad on the front cover protects the stroke end.
For the same 40 mm bore and 200 mm stroke, this JIS-standard housing is physically shorter than a comparable ISO 6432 cylinder, delivering a tangible packaging advantage in cramped machinery. The internal fixed TPU bumper pads decelerate the piston at the stroke extremes, though they do not provide adjustable cushioning. Because this specific SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors. Plan for a safe working load of roughly 377 N (about 60 percent of the 0.5 MPa rating), which translates to lifting a 32 kg part vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200CM Is Used
Injection Mold Ejection
Provides the robust 628.3 N push force required to eject dense plastic parts from tight mold tooling, where the shorter JIS body prevents interference with the press platen.
Package Diverting Arm
Drives a heavy-duty diverter arm on a packaging line, using the 200 mm stroke to push cartons between lanes while the SUS304 barrel withstands daily washdowns.
Pallet Lift Gate
Actuates a lower-tier pallet lift gate, safely moving components weighing up to 32 kg vertically when paired with a pilot check valve to secure the load.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200CM 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 provides 402.2 N. Since 40 mm is the largest bore in the MF family, moving beyond this capacity requires a different cylinder series entirely. The CM round-end back cover on this model suits rear pivot mounting arrangements, and it can be paired with LB foot, FA flange, SDB pivot-block, or TC trunnion hardware.
Note that a standard MF cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only soften the end-of-stroke impact and will not hold a load. For vertical or suspended loads, integrate an external rod lock or a pilot-operated check valve. Additionally, the 200 mm stroke demands careful alignment to prevent rod bending and premature seal wear from side loads. Air connects via a 1/4 inch port, and the male rod thread is M14x1.5.
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 MF40X200CM 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 inch air port and an M14x1.5 male rod thread.
No, this specific SKU lacks the internal magnet required for sensing. You must order the -S variant to use CMSG, DMSG, or EMSG switches. The unit features a CM round-end rear cover and fixed TPU bumper pads that decelerate the stroke end without acting as an adjustable cushion.
