Airtac MF32-40 Stainless Steel Mini Cylinder MF32X425SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X425SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 425mm 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 MF32X425SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore AirTAC mini cylinder handles demanding mid-range automation tasks. The JIS-standard round-body design is physically shorter than a comparable ISO 6432 unit for the same 425 mm stroke, yielding a tangible packaging advantage in tight machine cells. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the internal two-way seal retains an oil film for extended mechanical life.
Equipped with a piston magnet for position sensing, this unit accepts CMSG, DMSG, or EMSG switches to track the full 425 mm travel. Fixed TPU bumper pads and a front-cover anti-impact pad soften the end-of-stroke impact, though they decelerate rather than provide adjustable cushioning. For practical actuation at 0.5 MPa, plan for roughly 241 N of usable work, which translates to lifting about 20.5 kg vertically 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 MF32X425SCM Is Used
Carton Diverting
Pushes medium-weight packages onto secondary packaging lines using its 402.2 N thrust capacity over a 425 mm reach.
Vertical Parts Lift
Elevates 20 kg wip pallets between processing tiers, relying on the CMSG sensors to confirm the upper position.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, utilizing the CM round-end cover for self-aligning pivot mounting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X425SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push force at 0.5 MPa, whereas moving up to the MF40 provides 628.3 N. This model strikes a balance for medium payloads, but remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred—the bumpers only soften the stroke end and will not brake or hold a suspended load. To maintain vertical position, integrate an external rod lock or a pilot-operated check valve. The included CM round-end back cover suits rear pivot mounting, and the -S magnet enables solid sensor feedback across the 425 mm stroke. At this extended length, carefully manage side loading to prevent rod bending and premature seal wear.
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 MF32X425SCM FAQ
At 0.5 MPa, the push force is 402.2 N and the pull force is 345.6 N. 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. This 32 mm bore cylinder uses a 1/4" air port and an M10x1.25 male rod thread.
It features a SUS304 stainless barrel with riveted aluminium covers, making the JIS-standard body shorter than an ISO 6432 cylinder for the same stroke. The CM designation indicates a round-end back cover for pivot mounting. It includes a magnet for sensors but uses fixed TPU bumper pads for deceleration, not adjustable air cushions.
