Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCASDB
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCASDB is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MF32X25SCASDB
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers. The riveted rolling-packed structure shrinks the overall body length compared to an ISO 6432 unit of the same bore and stroke, yielding a tangible packaging advantage in tight machinery. A built-in piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
The piston relies on a heterogeneous two-way seal that retains an oil film for extended lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. At 0.5 MPa you can expect a real working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Air connects via a 1/4" port, and the rear pivot cover pairs seamlessly with the included SDB pivot block for articulated mounting.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCASDB Is Used
Clamp Actuation
Secures aluminium extrusions in a machining fixture using the 402.2 N push force, with the short 25 mm stroke keeping the clamp envelope compact.
Diverter Gate
Pivots a sorting flap on a packaging line via the CA rear pivot and SDB block, handling part weights up to the 20.5 kg vertical lift equivalent.
Component Insertion
Presses bearings into housings on an assembly carousel, relying on the DMSG sensor to confirm the 25 mm insertion depth.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCASDB the Right Cylinder?
When sizing this 32 mm bore unit, the adjacent MF25 generates 245.3 N at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N at the same pressure. If your air supply drops or the directional valve centres, the piston will drift because the fixed bumpers only decelerate the end of travel rather than locking the rod; suspend a load using a pilot-operated check valve or an external rod lock. The CA rear pivot and SDB block accommodate angular alignment, and the integrated magnet (-S) supports CMSG, DMSG, and EMSG sensors. Although the 25 mm stroke is short, always guide the tooling to prevent side-load bending on the 12 mm rod.
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 MF32X25SCASDB 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.
It is a JIS-standard round-body cylinder with a SUS304 stainless barrel and riveted aluminium covers, making the overall body shorter than a comparable ISO 6432 unit. It uses fixed TPU bumper pads rather than an adjustable cushion, and this SKU includes a CA rear pivot cover with an SDB pivot block for articulated mounting.
