Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20UTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MF32X20UTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder features a highly compact 20 mm stroke. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same envelope, it slots neatly into tight machine fixtures. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the internal two-way seal retains an oil film for extended operational life.
For practical sizing, plan your moving payload around 241 N of real work, which respects a 60 percent safety margin against the 0.5 MPa thrust. In vertical lifting scenarios, that same thrust translates to hoisting roughly 20.5 kg safely with a 2:1 factor. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to the -S variant. Fixed TPU bumper pads and a front-cover anti-impact pad soften the end-of-stroke impact, decelerating the motion without offering adjustable cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20UTC Is Used
Short-Stroke Clamping
Ideal for locking small aluminium extrusions in a machining cell, using the 402.2 N thrust to hold parts firmly against a stop without consuming valuable tooling length.
Package Diverter Gate
Mounts via the TC trunnion on a packaging line to flick lightweight cardboard cartons off a main conveyor belt, with the 20 mm stroke providing a fast, snappy actuation.
Pallet Stopper Pin
Functions as a springless stopper pin on a low-profile roller conveyor, deploying the 12 mm rod to halt pallets before they enter a robotic stretch-wrap station.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20UTC the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa if your load is lighter, while the MF40 steps up to 628.3 N for heavier demands. This model uses a 1/4" port and an M10x1.25 male rod thread. It arrives configured with a U flat-end back cover and a TC trunnion mount, giving you a pivoting centerline axis that accommodates slight misalignment on your fixture.
Keep in mind that a standard double-acting cylinder will drift if air pressure drops or the control valve is centred, as the fixed bumpers only soften the stroke end rather than locking the rod. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. Furthermore, the short 20 mm stroke keeps rod bending stress minimal, but always ensure the load travels along a straight axis to avoid side-loading the piston.
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 MF32X20UTC FAQ
This 32 mm bore cylinder uses a 1/4" air port and an M10x1.25 male rod thread. At 0.5 MPa it generates 402.2 N of push force and 345.6 N of pull force. 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, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG, or EMSG reed switches. You would need to specify the -S variant to enable magnetic sensing. The unit features a JIS-standard round body that is shorter than an ISO 6432 cylinder, includes fixed TPU bumper pads for end-of-stroke deceleration, and is equipped with a U flat-end back cover.
