Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 150mm 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 MF32X150SUTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore AirTAC mini cylinder is built around a JIS-standard round body. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. The riveted rolling-packed structure keeps the overall envelope shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length in tight fixtures.
The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Because this SKU includes the S suffix, it carries a built-in magnet for position sensing. 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.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SUTC Is Used
Package Diverting
Uses the 402.2 N push at 0.5 MPa to deflect medium-weight cartons on a packaging line via a TC trunnion-mounted actuator.
Clamp Actuation
Secures aluminium extrusions during CNC machining, relying on the 150 mm stroke to reach and hold parts firmly.
Vertical Lifting
Raises lightweight tote bins up to 20.5 kg against gravity, taking advantage of the two-way oil-retaining seal for smooth operation.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SUTC the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push force at 0.5 MPa, whereas moving up to the MF40 provides 628.3 N. This model features a U flat-end back cover and a TC trunnion mount, offering a pivot point that accommodates slight misalignment. The 150 mm stroke is well within the 500 mm standard limit, though at this extension you should ensure the load is guided to prevent rod bending and premature seal wear.
Air pressure both extends and retracts the rod, but a standard cylinder drifts if air is lost or the valve is centred. The TPU bumpers only decelerate the end of stroke and do not function as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Furthermore, the integrated magnet allows CMSG, DMSG, or EMSG switches to track piston position.
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 MF32X150SUTC FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/4" air port and has a 150 mm stroke.
The SUS304 stainless round body is physically shorter than an ISO 6432 cylinder for the same 32 mm bore and 150 mm stroke, saving mounting space. The included TC trunnion mount pairs with the U flat-end rear cover to allow pivoting, which helps absorb slight misalignment in your mechanical linkage.
