Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160CM 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 MF40X160CM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X160CM is a 40 mm bore double-acting JIS-standard round-body mini cylinder. It features a SUS304 stainless-steel barrel with aluminium covers joined by a riveted rolling-packed structure, resisting mild corrosion and washdown. Because the MF body is shorter than an ISO 6432 cylinder for the same 160 mm stroke, it saves valuable mounting length in tight fixtures.
The piston relies on a heterogeneous two-way seal that retains an oil film for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact. Plan for about 377 N of real work at 0.5 MPa, which means it lifts roughly 32 kg vertically with a 2:1 safety margin. This SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160CM Is Used
Pallet Diverting Gate
Actuates a heavy routing flap on a packaging line, using the 628.3 N push force to reliably shift loaded pallets onto a secondary conveyor track.
Press Fit Bushings
Pushes bronze bushings into aluminium housings on an assembly jig, where the 160 mm stroke provides ample reach and the CM rear cover allows a pivoting linkage.
Carton Lid Flap Folding
Folds heavy cardboard carton flaps prior to sealing, benefiting from the SUS304 stainless barrel's resistance to humid or washdown packing environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160CM the Right Cylinder?
At 0.5 MPa this 40 mm bore generates 628.3 N of push and 527.8 N of pull. If your fixture is over-specified, stepping down to the MF32 yields 402.2 N; since 40 mm is the largest available MF bore, moving higher requires a different cylinder family entirely. The 1/4" port and M14x1.5 male rod thread match the bore size.
The CM round-end back cover suits pivot-mount installations, complemented by LB, FA, SDB or TC brackets. Remember that a plain cylinder drifts when air is lost or the valve is centred—the TPU pads only decelerate the stroke end and act as neither a lock nor a brake. To secure a vertical load, specify an external rod lock or a pilot-operated check valve. Furthermore, the 160 mm stroke demands careful alignment to prevent rod bending under side loads.
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 MF40X160CM FAQ
This 40 mm bore double-acting cylinder has a 1/4" air port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the MF40X160CM-S variant for position sensing. The unit uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and its JIS-standard body is physically shorter than a comparable ISO 6432 cylinder.
