Airtac MF32-40 Stainless Steel Mini Cylinder MF32X650SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X650SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 650mm 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 MF32X650SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore JIS-standard round-body cylinder features a 650 mm stroke that exceeds the 500 mm standard limit, making it a made-to-order item for long-reach tasks. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for extended mechanical life. The 1/4" port and M10x1.25 male rod thread handle the required air volume for this extended length.
Because the MF body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length in tight machine layouts. Plan for a safe working load of about 241 N, which is roughly 60 percent of the 0.5 MPa rating, to ensure reliable operation. Alternatively, you can expect it to lift about 20.5 kg vertically when applying a 2:1 safety margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact, though they decelerate rather than provide adjustable cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X650SU Is Used
Long-Reach Diverting
Pushes parcels across a 650 mm transfer gap on packaging lines, utilising the 402.2 N thrust to overcome friction without requiring a larger 40 mm bore.
Vertical Material Lift
Elevates 20 kg component trays between conveyor tiers, relying on the U flat-end rear cover for stable base mounting and the -S magnet for top and bottom confirmation.
Washdown Gate Actuation
Opens and closes 650 mm safety doors in food processing areas, where the SUS304 stainless barrel withstands routine cleaning and the compact JIS body fits narrow frames.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X650SU the Right Cylinder?
When sizing this actuator, step down to the MF25 bore if your task requires only 245.3 N of push force at 0.5 MPa, or move up to the MF40 bore if you need a heavier 628.3 N thrust. Because the 650 mm stroke is non-standard and made-to-order, verify that your mounting arrangement supports the rod to prevent excessive side-loading and bending during extension. The included -S magnet enables position sensing with CMSG, DMSG, or EMSG switches, and the U flat-end back cover provides a straightforward rear mounting face.
Remember that a standard pneumatic cylinder cannot maintain its position if air pressure drops or the valve is centred, as the piston will drift and the bumpers only soften the end of travel rather than acting as a brake. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your circuit. For applications requiring adjustable end-of-stroke deceleration at high speeds, consider the MFC variable air cushion variant instead of the fixed bumper design.
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 MF32X650SU FAQ
This 32 mm bore double-acting cylinder pushes with 402.2 N and pulls with 345.6 N at 0.5 MPa. At 0.7 MPa, the push force is 563 N and the pull force is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa, and the air port size is 1/4".
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake. To hold a suspended load, you must add an external rod lock or a pilot-operated check valve.
