Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MF40X75SUTC
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting actuator handles heavy-duty positioning in tight spaces. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder, it saves valuable mounting length without sacrificing power. The SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments.
Equipped with a built-in piston magnet, the unit supports CMSG, DMSG, and EMSG sensors for end-of-stroke detection. Fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock, while the two-way oil-retaining seal ensures long service life. Plan for roughly 377 N of actual work at 0.5 MPa, or expect it to lift about 32 kg vertically with a safe 2:1 margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SUTC Is Used
Pallet Diverting Gate
Uses the 628.3 N push force to swing a heavy mechanical divert arm on a packaging line, routing cartons at high speed.
Press Pin Insertion
Drives a 16 mm rod downward to seat metal dowel pins into aluminum housings, relying on the fixed TPU bumper to absorb the impact.
Vertical Parts Lift
Elevates 32 kg material trays between conveyor tiers, taking advantage of the compact JIS body length to fit tight vertical elevators.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75SUTC the Right Cylinder?
When sizing this 40 mm bore actuator, verify your actual load requirements against the 628.3 N push rating at 0.5 MPa. If your application demands less force, stepping down to the 32 mm bore yields 402.2 N; since 40 mm is the largest available MF series bore, exceeding this capacity requires a different cylinder family entirely. The included TC trunnion mount pairs with the flat-end U back cover for pivoting articulation.
Remember that a standard double-acting cylinder naturally drifts if air pressure drops or the valve is centred, as the fixed bumpers only decelerate the stroke end rather than locking the rod. To suspend a load safely during an emergency stop, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. The 75 mm stroke is well within standard limits, but always guide the rod to prevent side-load bending.
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 MF40X75SUTC FAQ
This 40 mm bore double-acting cylinder uses a 1/4" air port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the MF body is JIS-standard and is simply shorter than an ISO 6432 cylinder for the same stroke, so ISO brackets will not fit. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion. The included TC trunnion mount and U flat-end back cover provide the necessary pivoting articulation.
