Airtac MF32-40 Stainless Steel Mini Cylinder MF40X170SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X170SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 170mm 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 MF40X170SCM
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting actuator tackles heavier fixturing tasks. Its SUS304 stainless barrel and riveted aluminium covers shrug off mild washdowns, while the piston's two-way oil-retaining seal maintains a steady lubricating film for a long service life. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder, it trims valuable mounting length in tight machinery.
The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches, and the CM round-end back cover simplifies rear pivot mounting. Fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shocks. For real-world work, plan for roughly 377 N of usable load at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X170SCM Is Used
Stamping Ejector
Pushes finished metal blanks out of a progressive die using the full 628.3 N push force at 0.5 MPa to overcome residual friction.
Pallet Diverter
Extends 170 mm to reroute heavy timber pallets onto a secondary packaging line, utilizing the CM round-end cover for a smooth rear pivot.
Carton Flap Folder
Drives a mechanical arm to fold corrugated cardboard flaps prior to sealing, benefiting from the compact JIS body length in dense conveyor layouts.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X170SCM the Right Cylinder?
When sizing this unit, dropping down to the 32 mm bore reduces the 0.5 MPa push force to 402.2 N, while stepping up is impossible as 40 mm is the largest available MF diameter. This model uses a 1/4" air port and an M14x1.5 male rod thread. The 170 mm stroke is well within the 500 mm standard limit, though you should still minimize side loading to prevent rod bending over that travel distance.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU pads only soften the end of stroke rather than locking the piston. To suspend a load securely during an outage, install an external rod lock or a pilot-operated check valve in the air circuit.
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 MF40X170SCM FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. At 0.5 MPa it provides 628.3 N of push and 527.8 N of pull force. At 0.7 MPa, the push increases to 879.6 N and the pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
This SKU includes the -S magnet, so it fully supports CMSG, DMSG, and EMSG electronic or reed switches. It relies on fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for variable cushioning, look at the MFC variant.
