Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MF40X175SCM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X175SCM is a robust 40 mm bore double-acting mini cylinder built to JIS standards. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments, while the internal two-way seal retains an oil film for extended mechanical life. Because this round-body design is physically shorter than a comparable ISO 6432 cylinder, it saves valuable mounting length in tight machinery.
This 175 mm stroke unit features a CM round-end rear cover and a 1/4" port. It includes a built-in piston magnet for position sensing, and fixed TPU bumper pads work alongside a front-cover anti-impact pad to soften stroke-end impacts. For practical sizing, plan for roughly 377 N of usable work at 0.5 MPa, which translates to safely lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCM Is Used
Pallet Diverting Gate
Uses the 628.3 N push force at 0.5 MPa to swing a heavy diverting arm on a packaging line, routing dense cartons at speed.
Press Feed Lowering
Lowers a 32 kg material feed roll into position using the 175 mm stroke, relying on the CM round-end cover for smooth pivot articulation.
Storage Tray Indexing
Pushes loaded metal trays into a storage rack, where the SUS304 stainless barrel withstands occasional washdowns during facility cleaning.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCM the Right Cylinder?
When sizing this 40 mm bore unit, stepping down to an MF32 drops the 0.5 MPa push force to 402.2 N, while the 40 mm bore is the largest available in the MF family at 628.3 N. The 175 mm stroke provides ample travel but demands careful alignment to prevent rod bending under side loads. The included -S magnet enables CMSG, DMSG, or EMSG switches for end-of-stroke confirmation.
Remember that fixed bumper pads only decelerate the piston near the stroke end; they do not function as a brake. If your application must prevent drift on air loss or valve centring, fit an external rod lock or pilot-operated check valve. The CM round-end back cover suits pivot mounting, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion brackets.
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 MF40X175SCM FAQ
This 40 mm bore cylinder uses a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The riveted SUS304 stainless and aluminium round body is shorter than an ISO 6432 cylinder for the same stroke, saving space. The -S suffix means it has a piston magnet for CMSG, DMSG, or EMSG switches. Fixed TPU bumpers soften impact but do not adjust like the MFC cushioned variant.
