Airtac MF32-40 Stainless Steel Mini Cylinder MF32X220SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X220SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 220mm 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 MF32X220SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore unit is engineered for tight fixture layouts where every millimetre counts. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder for the same 220 mm stroke, it shrinks the overall packaging envelope without sacrificing travel. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for long service life.
At 0.5 MPa you can plan for roughly 241 N of actual work, which translates to lifting about 20.5 kg vertically with a sensible 2:1 safety margin. The 1/4" port feeds the chamber efficiently, and fixed TPU bumper pads alongside a front-cover anti-impact pad soften the end-of-stroke impact. Since this SKU carries the -S suffix, a built-in piston magnet is ready for CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X220SU Is Used
Package Diverting Gate
Actuates a routing flap on a 220 mm stroke to sort medium-weight cartons on a packaging line, using the compact JIS body length to fit between tight conveyor frames.
CNC Lathe Door Slide
Opens and closes a sliding safety guard on a CNC turning center, where the SUS304 barrel withstands splashing coolant and the U flat-end cover mounts directly to the machine base.
Vertical Parts Elevator
Lifts 18 kg tote bins of machined hardware between processing tiers, relying on the 402.2 N push rating at 0.5 MPa and a DMSG sensor to confirm the top position.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X220SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. This model hits a solid middle ground for 220 mm of travel. The U-style flat-end back cover mounts flush against machine frames, and you can pair it with LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions depending on the load path. For a 220 mm stroke, ensure your mounting geometry minimizes side-load and rod-bending moments to prevent premature seal wear.
Remember that fixed TPU pads only decelerate the stroke end; they do not act as a lock. If air pressure drops or the valve is centred, the piston will drift and drop the load. To maintain vertical position safely, install an external rod lock or a pilot-operated check valve in the air line.
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 MF32X220SU FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only soften the stroke end and do not function as a brake. If air is lost, the piston will drift. You must use an external rod lock or pilot check valve to hold a vertical load. The -S magnet allows CMSG/DMSG/EMSG sensors, and the JIS round body is shorter than an ISO 6432 equivalent.
