Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MF32X250SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting AirTAC MF32X250SCA mini cylinder is built around a JIS-standard round body. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 250 mm stroke, it saves valuable mounting length in tight fixtures.
The unit includes fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impact. It carries an -S piston magnet for position sensing and a CA pivot back cover. Plan for a safe working load of about 241 N (60% of the 0.5 MPa rating); vertically, it lifts about 20.5 kg with a 2:1 margin. The 1/4" port and M10x1.25 male rod thread accommodate robust airflow for speeds of 30-800 mm/s.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCA Is Used
Package Diverter Arm
Swings a sorting gate on a packaging line using the CA pivot mount, relying on the 402.2 N push force at 0.5 MPa to deflect heavy cartons smoothly.
CNC Tool Ejection
Ejects machined aluminium parts from a fixture where the shorter JIS body length prevents interference with the spindle during operation.
Pallet Stopper Gate
Acts as a raised stop pin for pallets on a roller conveyor, safely holding loads up to 20.5 kg vertically before releasing them downstream.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCA the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, while stepping up to the MF40 provides 628.3 N. This model hits a strong middle ground for mid-range actuation. Note that a plain double-acting cylinder drifts if air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a lock. To suspend a load securely, install an external rod lock or a pilot-operated check valve.
The included -S magnet enables CMSG, DMSG, or EMSG switches for precise end-of-stroke detection. The CA rear pivot cover suits angular movement, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion mounts. At 250 mm, verify side loading to prevent rod bending, and consider the MFC variant if your application requires adjustable air cushioning for higher kinetic energy.
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 MF32X250SCA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a 1/4" air port and an M10x1.25 male rod thread.
No, a standard double-acting cylinder drifts when air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the piston near the stroke end and do not act as a brake. You must add an external rod lock or pilot check valve to hold a load securely.
