Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MF32X450SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work within a compact footprint. For the same 32 mm bore and 450 mm stroke, the SUS304 stainless steel barrel and riveted aluminium covers create a body notably shorter than an ISO 6432 unit, saving valuable mounting length. The integrated piston magnet (-S) directly supports CMSG, DMSG, and EMSG reed or electronic switches for precise end-of-stroke detection.
Built for durability, the heterogeneous two-way seal retains an oil film for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. At 0.5 MPa, you can plan for a safe working load of roughly 241 N, or lift about 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and CA pivot back cover ensure robust airflow and flexible rear mounting for long-stroke pivoting tasks.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCA Is Used
Package Diverting Arm
Swings a sorting gate along a packaging line using the CA pivot mount, relying on the 402.2 N push force to deflect heavy cartons at high speed.
Vertical Parts Lift
Raises lightweight industrial trays using the 450 mm stroke, safely lifting approximately 20.5 kg loads with a 2:1 vertical margin.
Pneumatic Clamping Fixture
Secures aluminum castings for machining operations, where the SUS304 stainless barrel resists mild coolant washdown.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SCA the Right Cylinder?
When sizing this 32 mm bore, verify your force requirements against the 402.2 N push at 0.5 MPa. If your application is lighter, the smaller MF25 bore provides 245.3 N; if you need more power, the larger MF40 bore offers 628.3 N. Because this is a 450 mm stroke, maintain proper guiding to prevent rod bending and side-load damage. The CA pivot back cover is ideal for accommodating lateral movement on long strokes. If your process absolutely must hold a load vertically during air loss or valve centering, note that a plain cylinder drifts; the bumper pads only decelerate the end of stroke and act as neither a brake nor a lock. You must add an external rod lock or a pilot-operated check valve for secure positioning.
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 MF32X450SCA FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. 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.
Yes, the -S suffix indicates a built-in magnet allowing you to mount CMSG, DMSG, or EMSG switches. It is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 cylinder for the same bore and stroke, providing a packaging advantage without conforming to ISO 6432.
