Airtac MF32-40 Stainless Steel Mini Cylinder MF32X190SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X190SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm 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 MF32X190SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X190SU is a double-acting JIS-standard round-body mini cylinder built around a SUS304 stainless barrel with riveted aluminium covers. Because its physical body is shorter than an ISO 6432 cylinder of the exact same bore and stroke, it shrinks the total footprint required for tight machine fixtures. The 190 mm stroke operates at 30-800 mm/s via a 1/4 inch port, while fixed TPU bumper pads and a front-cover anti-impact pad absorb the end-of-stroke shock.
The heterogeneous two-way piston seal retains an oil film for extended mechanical life, and the -S suffix equips this unit with a magnet for CMSG, DMSG, or EMSG position switches. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The flat-end U back cover provides a flush mounting surface for straightforward rear fixation.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X190SU Is Used
Package Diverter Arm
Pushes corrugated cartons onto a secondary packing line using 402.2 N of thrust at 0.5 MPa, with the 190 mm stroke clearing the primary belt.
CNC Lathe Door Operator
Slides a heavy machine enclosure open and closed, where the SUS304 barrel withstands splashing coolant and the compact JIS body saves axial length.
Pallet Component Sorter
Lifts a 20.5 kg fixture vertically with a 2:1 safety margin, using the flat-end U rear cover for rigid frame mounting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X190SU the Right Cylinder?
When sizing this 32 mm bore, dropping down to the MF25 reduces the 0.5 MPa push capability to 245.3 N, whereas stepping up to the MF40 raises it to 628.3 N. If your process demands a locked rod during an air-loss event or when a valve is centred, note that this base cylinder will drift; the fixed bumpers only decelerate the stroke end and act as neither a brake nor a hold. You must add an external rod lock or a pilot-operated check valve for secure load holding.
This SKU includes the -S magnet for electronic or reed sensor tracking, and the U flat-end rear cover suits direct bulkhead mounting. For a 190 mm stroke, ensure your front pivot or flange supports the rod laterally to prevent bending under side loads. If your cycle speed creates excessive end-impact shock beyond what the fixed pads can absorb, consider the MFC variant which features adjustable air cushioning.
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 MF32X190SU FAQ
This 32 mm bore cylinder features a 1/4 inch port and a male M10x1.25 rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
It does not conform to ISO 6432, though its JIS-standard round body is deliberately shorter than an ISO 6432 cylinder for the same 32x190 dimensions, saving space. For detection, the -S suffix provides a piston magnet compatible with CMSG, DMSG, and EMSG switches.
