Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 90mm 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 MF32X90SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X90SU is a JIS-standard round-body mini cylinder built for tight machinery layouts. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for long mechanical life. Because the riveted body is physically shorter than an ISO 6432 cylinder of the same 32 mm bore and 90 mm stroke, it saves valuable mounting length in compact fixtures.
This double-acting actuator uses fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impact, operating at speeds from 30-800 mm/s. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position detection, and the U flat-end back cover simplifies direct rear mounting. Plan for a safe working load of roughly 241 N, which lets you lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90SU Is Used
Carton Diverting Gate
Swing a lightweight routing gate on a packaging line, where the 402.2 N push force easily overcomes flap friction to redirect boxes at high speed.
Clamp Ejection Arm
Pushes a finished aluminium bracket out of a CNC machining fixture, using the U flat-end back cover to mount flush against the machine frame.
Vertical Parts Press
Presses a bearing into a housing on an assembly table, safely lifting parts under 20.5 kg with the 2:1 margin while the TPU pads absorb the impact.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90SU the Right Cylinder?
When sizing this 32 mm bore, compare its 402.2 N push force at 0.5 MPa against the smaller MF25 at 245.3 N or the larger MF40 at 628.3 N to match your pneumatic setup. The 1/4" port and M10x1.25 male rod thread are fixed for this bore. To support position feedback, the -S magnet allows CMSG, DMSG or EMSG switches to be fitted directly to the groove.
If your application requires the rod to stay put after a valve centres or air pressure drops, this cylinder will drift; the TPU bumpers only decelerate the stroke end rather than locking the load. You should add an external rod lock or a pilot-operated check valve for secure load holding. Furthermore, at this 90 mm stroke, ensure your mounting arrangement—whether LB foot, FA flange or TC trunnion—prevents side loads that could bend 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 MF32X90SU FAQ
This 32 mm bore double-acting 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 force of 82 kgf at 1.0 MPa.
The JIS-standard riveted SUS304 stainless body is physically shorter than a comparable ISO 6432 cylinder, saving mounting length in tight fixtures. It relies on fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and the included -S magnet enables CMSG, DMSG or EMSG sensors.
