Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50UFA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50UFA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 50mm 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 MF32X50UFA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is engineered for tight machinery layouts. Because its SUS304 stainless barrel and riveted aluminium covers form a shorter overall body than a comparable ISO 6432 unit, you save valuable mounting length without sacrificing stroke. The 1/4" port and 50 mm stroke make it highly versatile for mid-force tasks.
The riveted rolling-packed structure resists mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Fixed TPU bumper pads and a front-cover anti-impact pad work together to soften stroke-end impact. Plan for roughly 241 N of actual work at 0.5 MPa, or lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50UFA Is Used
Clamping Machined Aluminium Parts
Holds mid-weight aluminium workpieces against a milling fixture using 402.2 N of push force at 0.5 MPa without flexing.
Package Diverting Arm
Extends a 50 mm stroke to push cardboard cartons from a main conveyor belt to a secondary packaging lane.
Pallet Stopper Gate
Acts as a pneumatic stop in a warehouse pallet flow system, using its FA flange to withstand repeated side impacts.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50UFA the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. This SKU includes a U flat-end back cover and an FA flange for secure mounting. Note that because this specific code lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors; order the -S variant if position feedback is required. If your mechanism loses air or the valve is centred, the piston will drift, as the fixed bumpers only decelerate the stroke end rather than locking the load. For secure holding, integrate an external rod lock or a pilot-operated check valve.
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 MF32X50UFA FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male 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 of 82 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an MF32 model with the -S suffix for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
