Airtac MF32-40 Stainless Steel Mini Cylinder MF32X160U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X160U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 160mm 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 MF32X160U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles a 160 mm stroke with a compact JIS-standard round body. Because the SUS304 stainless steel barrel and riveted aluminium covers are shorter than an ISO 6432 cylinder of the same bore and stroke, it saves valuable mounting length in tight machine fixtures. The riveted rolling-packed structure shrugs off mild corrosion and washdown, while the piston's two-way seal retains an oil film for long life.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end decelerates smoothly without adjustable cushioning. Plan for roughly 241 N of actual work at 0.5 MPa, which means you can safely lift about 20.5 kg vertically with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; choose the -S variant if you require position detection. Air connects via a 1/4 inch port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X160U Is Used
Carton Diverter Arm
Swings a guide rail to sort medium-weight packaging on a 1/4 inch ported pneumatic line, using the 160 mm stroke to clear adjacent lanes.
Press Ejector Station
Kicks stamped metal parts out of a die using 402.2 N of push force, relying on the SUS304 barrel to withstand light coolant splash.
Vertical Parts Gate
Raises a 20 kg material shuttle gate via the U flat-end rear cover, taking advantage of the shorter JIS body to fit cramped dock enclosures.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X160U the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N at 0.5 MPa, while the larger MF40 pushes 628.3 N at 0.5 MPa. If your fixture demands precise stopping or heavy vertical holding, remember that a plain cylinder drifts when air is lost or the valve is centred. The bumper pads only soften the stroke end rather than locking the rod, so integrate an external rod lock or a pilot-operated check valve for suspended loads.
The U flat-end back cover on this 160 mm stroke unit suits direct rear mounting, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion hardware. At 160 mm of travel, watch for side loads that could bend the 12 mm rod. Without the -S magnet option, this unit cannot host reed or solid-state switches.
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 MF32X160U FAQ
This 32 mm bore double-acting cylinder uses a 1/4 inch port and a male M10x1.25 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 of 82 kgf at 1.0 MPa.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The U flat-end back cover allows direct mounting, and the fixed TPU bumpers simply decelerate the stroke end without acting as a lock.
