Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190SU 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 MF40X190SU
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X190SU is a robust 40 mm bore double-acting mini cylinder built to JIS standards. Its SUS304 stainless steel barrel and riveted aluminium covers form a compact round body that is physically shorter than a comparable ISO 6432 unit, providing a tangible packaging advantage in tight machinery. The 1/4" port and M14x1.5 male rod thread handle the required air volume for this high-force class.
Because the 190 mm stroke generates significant kinetic energy, the fixed TPU bumper pads and front-cover anti-impact pad work together to soften end-of-stroke impacts. For practical sizing, plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, and the integrated magnet (-S) enables position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190SU Is Used
Pallet Diverter Gate
Shifts heavy wood pallets on a packaging line using the full 628.3 N push force, with the 190 mm stroke clearing the lane for rerouting.
Press Fit Subassembly
Pushes bronze bushings into aluminium housings on an automotive fixture, utilising the compact JIS body length to fit between existing spindles.
Carton Stack Rejector
Shoves overweight corrugated cartons off a roller table at speed, relying on the TPU bumper pads to absorb the impact at the end of the 190 mm extension.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X190SU the Right Cylinder?
When sizing this 40 mm bore, compare it directly with the smaller MF32, which yields 402.2 N of push at 0.5 MPa; stepping up to the MF40 provides a substantial 628.3 N for heavier fixtures. Since 40 mm is the largest bore in the MF series, moving beyond this capacity requires a different cylinder family. The included U flat-end back cover suits direct rear mounting, while LB foot, FA flange, SDB pivot, and TC trunnion brackets remain available for varied orientations.
The built-in magnet allows CMSG, DMSG, or EMSG switches to track the 190 mm travel. Remember that air pressure alone will not maintain a load if supply drops or the valve centres—the piston will drift, as the TPU pads only decelerate the stroke end rather than locking the rod. Employ a pilot check valve or external rod lock for strict position holding. At 190 mm, also verify your guiding structure 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 MF40X190SU FAQ
This 40 mm bore double-acting cylinder uses a 1/4" 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.
The MF body is built to JIS standards and is physically shorter than an ISO 6432 cylinder for the same 40x190 dimensions, but it does not conform to the ISO standard. It uses fixed TPU bumper pads rather than an adjustable air cushion. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG sensors directly to detect the piston.
