Airtac MF32-40 Stainless Steel Mini Cylinder MF32X55SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X55SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 55mm 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 MF32X55SCM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X55SCM is a 32 mm bore, double-acting JIS-standard round-body mini cylinder. Because its riveted rolling-packed structure is physically shorter than an ISO 6432 cylinder of the identical bore and stroke, it shrinks the total mounting envelope for tighter machine layouts. The SUS304 stainless steel barrel pairs with aluminium covers to resist mild corrosion and light washdown, while the piston's two-way seal retains an oil film for extended lifespan.
This specific SKU includes a built-in piston magnet (-S) for direct mounting of CMSG, DMSG, or EMSG reed and electronic switches, alongside a CM round-end rear cover. The fixed TPU bumper pads and front-cover anti-impact pad soften stroke-end impact without offering adjustable cushioning. For practical actuation at 0.5 MPa, plan for a safe working load of roughly 241 N, which means it can vertically lift about 20.5 kg with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread ensure robust pneumatic and mechanical connections.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X55SCM Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, utilizing the 402.2 N push force to reliably redirect heavy cartons at high cycling speeds.
CNC Lathe Door Indexing
Opens and closes a sliding safety shield on a machine tool, where the JIS compact body saves valuable mounting length along the linear guide.
Pallet Component Pusher
Sweeps loose components into a palletizing station, lifting parts weighing up to 20.5 kg vertically with a safe 2:1 structural margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X55SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 drops the 0.5 MPa push force to 245.3 N, whereas moving up to the MF40 increases it to 628.3 N. If your application requires the piston to freeze in place during a compressed air loss or when a valve is centred, note that this standard cylinder will drift; the TPU bumpers only decelerate the stroke end and do not act as a braking mechanism. You must pair it with an external pilot-operated check valve or a dedicated rod lock to hold a suspended load safely.
The CM round-end back cover suits rear pivot mounting arrangements, and the integrated magnet allows seamless position sensing. Operating across a 30-800 mm/s speed range, the 55 mm stroke keeps the rod extension compact, though you should still verify that side loads are minimized to prevent rod bending over time.
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 MF32X55SCM FAQ
The 32 mm bore provides a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It features a 1/4" air port and an M10x1.25 male rod thread.
No, the MF is a JIS-standard round-body cylinder, not an ISO 6432 unit, though its riveted stainless-steel body is intentionally shorter than an ISO 6432 equivalent to save space. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. The -S magnet allows CMSG/DMSG/EMSG switches for position sensing.
