Airtac MF32-40 Stainless Steel Mini Cylinder MF40X600SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X600SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 600mm 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 MF40X600SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning tasks. The 600 mm stroke is a made-to-order length exceeding the 500 mm standard maximum, so expect a longer lead time for this specific configuration. Built with a SUS304 stainless-steel barrel and riveted aluminium covers, the riveted rolling-packed structure resists mild corrosion and washdown environments. The piston relies on a heterogeneous two-way seal that retains an oil film for long-term lubrication, while a fixed anti-impact pad on the front cover protects the assembly.
Because the MF body is physically shorter than an ISO 6432 cylinder for the same 40 mm bore and 600 mm stroke, it saves valuable mounting length in tight machinery layouts. Fixed TPU bumper pads at both ends soften the stroke-end impact by decelerating the piston, though they do not provide adjustable cushioning. For practical actuation at 0.5 MPa, plan for about 377 N of actual work output, which equates to lifting roughly 32 kg vertically with a 2:1 safety margin. This SKU includes a built-in magnet for position sensing and features a flat-end U back cover.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X600SU Is Used
Pallet Diversion
Pushes heavy loaded pallets sideways onto secondary packaging lines using its 628.3 N thrust and extended 600 mm reach.
Press Feed Lowering
Lowers heavy stamping blanks into press dies, utilizing the flat-end U back cover for stable rear mounting against the machine frame.
High-Bay Tray Handling
Extends deep into automated storage racks to extract or insert product trays, relying on the -S magnet for precise position feedback.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X600SU the Right Cylinder?
When sizing this 40 mm bore actuator, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which provides 402.2 N. Since 40 mm is the largest available bore in the MF series, moving beyond this capacity requires an entirely different cylinder family. The integrated -S magnet enables CMSG, DMSG, or EMSG electronic and reed switches for end-of-stroke confirmation. The 1/4" port matches the bore size, and the male M14x1.5 rod thread handles the substantial thrust.
Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the TPU bumpers only decelerate the end of travel and act as neither a brake nor a lock. To suspend a vertical load safely during an outage, install an external rod lock or a pilot-operated check valve. Additionally, the extended 600 mm stroke demands careful mounting to prevent rod bending and side-load damage, making TC trunnion or SDB pivot blocks preferable to rigid LB foot mounts for maintaining alignment.
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 MF40X600SU FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it provides 628.3 N push and 527.8 N pull. At 0.7 MPa it provides 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston at stroke end and do not function as a brake or load lock; use a pilot check valve for holding. Also, the 600 mm stroke is non-standard and made-to-order, exceeding the 500 mm maximum standard stroke. The JIS-standard round body is notably shorter than an ISO 6432 cylinder of the same bore and stroke.
