Airtac MF32-40 Stainless Steel Mini Cylinder MF32X30U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X30U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 30mm 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 MF32X30U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built for tight machinery spaces. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for extended mechanical life. The 1/4" port and 30 mm stroke keep the envelope compact.
For the same bore and stroke, the MF body is physically shorter than an ISO 6432 cylinder, delivering a real packaging advantage in dense fixtures. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact by decelerating the piston. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches; you would need the -S variant for sensing. Plan for a safe working load of roughly 241 N (about 60% of the 0.5 MPa rating), which translates to lifting a 20.5 kg mass vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X30U Is Used
Pallet Diverter Gate
Actuates a routing flap on a packaging line, using the 30 mm stroke to push pallets onto a parallel conveyor with 402.2 N of extending force.
CNC Lathe Bar Feeder
Advances raw stock into a collet chuck, where the SUS304 stainless barrel withstands splash from cutting fluids and the compact length saves floor space.
Component Press Fit
Pushes a bearing housing into an aluminium casing, applying a safe working load of around 241 N without overstressing the surrounding fixture.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X30U the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: step down to an MF25 for 245.3 N at 0.5 MPa, or step up to an MF40 if you need 628.3 N. This MF32X30U features a U-type flat-end back cover, making it easy to mount flush against a stationary frame or hard stop. It uses fixed TPU bumpers to decelerate the stroke end, not an adjustable air cushion (look to the MFC variant for adjustable cushioning).
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the bumpers only soften the end of travel rather than locking the rod. To suspend a load safely, fit an external rod lock or a pilot-operated check valve. Additionally, because this unit has no internal magnet, position sensing is impossible without switching to the -S version.
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 MF32X30U FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, because this specific SKU lacks the internal magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must specify the -S variant. The U-type flat-end back cover allows flush mounting against machine frames, and the JIS-standard body is shorter than an ISO 6432 cylinder of the same bore and stroke.
