Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm 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 MF40X160U
Generating 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight machinery envelopes. Because the SUS304 stainless barrel and riveted aluminium covers yield a shorter overall body than an equivalent ISO 6432 unit, you reclaim valuable mounting length. The internal piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shocks. Air connects via a 1/4" port, driving the 16 mm rod at speeds between 30 and 800 mm/s.
Planning actual workloads around the 0.5 MPa rating means expecting a safe output of roughly 377 N. Alternatively, it lifts about 32 kg vertically when applying a 2:1 safety margin. This specific configuration includes a U flat-end back cover. Note that this SKU lacks a magnet; adding the -S option is required to mount CMSG, DMSG, or EMSG sensors.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160U Is Used
Pallet Diverter Gate
Actuates heavy routing gates on packaging lines, using its 628.3 N thrust to positively shift loaded pallets without body flex.
Press Fit Pin Insertion
Drives solid dowel pins into thick steel fixtures, where the 40 mm bore provides the necessary downward force to seat the pins flush.
Container Lid Clamping
Secures heavy industrial container lids during filling operations, using the U flat-end rear cover for stable rigid mounting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160U the Right Cylinder?
When sizing this 40 mm bore, compare it directly with the smaller MF32, which provides 402.2 N of push at 0.5 MPa. If the MF32 lacks the necessary thrust, this model steps up the force, but remember that 40 mm is the largest bore in the MF family. The 160 mm stroke is well within the 500 mm standard limit, though long strokes demand careful alignment to prevent rod bending and premature seal wear.
The fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as a brake. If your application must prevent drift upon air loss or valve centering, install an external rod lock or a pilot-operated check valve. Furthermore, this non-magnetic version cannot accept position 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 MF40X160U FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore cylinder uses a 1/4" air port and an M14x1.5 male rod thread.
It features a JIS-standard SUS304 stainless round body with riveted aluminium covers, making it shorter than an ISO 6432 cylinder of the same bore and stroke. It uses fixed TPU bumper pads to decelerate at the stroke end rather than an adjustable air cushion. Since this specific SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
