Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SUFA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SUFA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MF32X100SUFA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a 32 mm bore and 100 mm stroke. 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 extended mechanical life. Because the MF body is shorter than a comparable ISO 6432 cylinder for the same envelope dimensions, it provides a tangible packaging advantage in tight machinery.
Equipped with a built-in magnet (-S) for CMSG, DMSG, or EMSG switches, this unit also features a U flat-end back cover and an FA flange for direct mounting. The 1/4" port and M10x1.25 male rod thread accommodate robust airflow and linkage. For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact without acting as an adjustable cushion.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SUFA Is Used
Package Diverting Gate
Actuates a routing flap on a 400 mm wide packaging belt, using the 402.2 N thrust to push corrugated cartons weighing up to 20 kg into secondary sorting lanes.
CNC Lathe Door Shuttle
Opens and closes a sliding safety blast door on a horizontal turning centre, where the compact JIS body length saves valuable floor space without sacrificing the 100 mm travel.
Tote Stacking Stopper
Deploys a physical stop block to halt incoming plastic totes on a gravity roller conveyor, relying on the fixed TPU bumper pads to absorb the repeated impact of arriving loads.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SUFA the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 generates 245.3 N of push force at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N. If your application demands holding a load vertically during an air loss or valve centre state, note that the piston will drift; the TPU bumpers only decelerate the stroke end and do not function as a brake. You must incorporate an external rod lock or a pilot-operated check valve to secure the payload. The included FA flange ensures rigid front mounting, and the U flat-end rear cover provides a flush back surface for stable back-end placement.
With a 100 mm stroke, maintaining rod alignment is critical to prevent side-loading and premature seal wear. The integrated magnet allows seamless position detection using CMSG, DMSG, or EMSG sensors without adding external physical switches. Operating speed spans 30-800 mm/s, making it highly versatile for general automation tasks.
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 MF32X100SUFA FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. The double-acting thrust is 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
It is a JIS-standard round-body cylinder with a SUS304 stainless barrel and riveted aluminium covers, making its overall body shorter than an ISO 6432 cylinder of the same bore and stroke. This specific SKU includes an FA flange for front mounting and a U flat-end back cover. It uses fixed TPU bumper pads to decelerate the stroke, not an adjustable air cushion.
