Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 190mm 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 MF40X190CA
Generating 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore JIS-standard round-body cylinder provides robust actuation for demanding fixtures. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. A practical output to expect is about 377 N of real work, which equates to lifting a 32 kg part vertically with a 2:1 safety margin.
Because the MF body is physically shorter than an ISO 6432 cylinder for the same 190 mm stroke, it saves valuable mounting length in tight machinery. The stroke end is decelerated by fixed TPU bumper pads and a front-cover anti-impact pad, though these do not act as an adjustable cushion. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches; the 1/4" port and M14x1.5 male rod thread match the 40 mm bore specification.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190CA Is Used
Stamping Press Ejection
Uses the 628.3 N push force at 0.5 MPa to knock stamped metal blanks out of a die, relying on the CA pivot to absorb slight angular misalignment.
Heavy Carton Sealing
Drives the sealing head of a case erector where the shorter JIS body prevents interference with the conveyor belt framework.
Pallet Diverting
Pushes loaded pallets onto a secondary roller lane, taking advantage of the 32 kg safe vertical lift equivalent to handle heavy product inertia.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190CA the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive for your cycle, the smaller MF32 bore drops the push force to 402.2 N, but since 40 mm is the largest available MF size, you cannot step up further within this series for heavier demands. The CA back cover provides a rear pivot mount, which pairs well with SDB pivot blocks for angular alignment, but remember that a plain cylinder drifts when air is removed or a valve is centred—install an external rod lock or pilot check valve if the load must be held. At 190 mm, the Ø16 mm rod is well within the 500 mm standard limit, yet side loading should still be minimized to prevent rod bending and premature seal 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 MF40X190CA FAQ
This 40 mm bore double-acting cylinder pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The air port is 1/4" and the male rod thread is M14x1.5.
No, because this model lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The unit features a CA pivot back cover and fixed TPU bumper pads that decelerate the stroke end but do not function as an adjustable air cushion.
