Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 375mm 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 MF32X375SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is engineered for tight machinery layouts. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. The piston relies on a two-way oil-retaining seal, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end impact. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.
For the same 32 mm bore and 375 mm stroke, the MF body is physically shorter than a comparable ISO 6432 cylinder, delivering a real packaging advantage in compact fixtures. The 1/4" port feeds the 12 mm rod to deliver 345.6 N of pull force at 0.5 MPa. Plan for roughly 241 N of actual work at that pressure, which translates to safely lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCA Is Used
Pallet Diverting Gate
Swings a routing flap on a packaging line using the CA pivot mount, applying 402.2 N at 0.5 MPa to push heavy cardboard cartons onto a secondary track.
CNC Lathe Bar Feeder
Advances raw steel stock through a guide tube, where the 375 mm stroke accommodates long material lengths and the -S magnet triggers a DMSG sensor to confirm feed completion.
Vertical Parts Lift
Raises lightweight plastic totes in a classifying machine, safely lifting roughly 20.5 kg loads while the SUS304 barrel withstands occasional coolant splashes.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCA the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 yields 245.3 N of push at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. If your process loses air or the valve centres, this plain cylinder will drift and cannot hold a load; the bumpers only decelerate the end of travel rather than acting as a brake. Secure a suspended mass using an external rod lock or a pilot-operated check valve. The built-in CA pivot back cover suits articulated rod-end loads, and you can mount the body via LB foot, FA flange, SDB pivot, or TC trunnion brackets. On a 375 mm stroke, minimize side-loading to prevent rod bending and premature seal wear.
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 MF32X375SCA FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. 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.
The CA back cover provides a rear pivot point for articulated mounting. Fixed TPU bumper pads decelerate the piston at the stroke ends to reduce impact, but they do not provide adjustable air cushioning. The JIS-standard round body is also shorter than an ISO 6432 cylinder of the same bore and stroke.
