Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125SCMLB
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125SCMLB is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MF32X125SCMLB
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder integrates an LB foot mount and a CM round-end rear cover. Because the JIS-standard round-body design is physically shorter than an ISO 6432 cylinder for the same 125 mm stroke, it saves valuable mounting length in tight machinery. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way oil-retaining piston seal ensures long-term lubrication. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact without offering adjustable cushioning. The 1/4" port drives the 12 mm rod, and the built-in -S magnet supports CMSG, DMSG, or EMSG position switches.
For practical sizing, plan for a safe working load of roughly 241 N, which is about 60% of the 0.5 MPa push rating. Alternatively, it can vertically lift around 20.5 kg with a 2:1 safety margin, letting you match real part weights directly. Operating between 0.15 and 1.0 MPa at speeds of 30-800 mm/s, this unit relies on its bumpers purely for end-deceleration. If your process demands position holding upon air loss, you must add an external rod lock or pilot check valve, as the piston will drift when unpressurized.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125SCMLB Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust, fitting easily into tight transfer gaps due to the short JIS body.
Clamp Actuation
Secures aluminium extrusions during machining operations, safely applying around 241 N of working clamping force at 0.5 MPa.
Vertical Part Lifting
Raises lightweight plastic totes weighing up to 20.5 kg vertically out of a storage rack, relying on the double-acting stroke for positive retraction.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125SCMLB the Right Cylinder?
When sizing this 32 mm bore option, verify if the smaller MF25 provides adequate thrust at 245.3 N, or if stepping up to the MF40 is necessary to achieve 628.3 N at 0.5 MPa. This model includes the LB foot mounting bracket and a CM round-end back cover, so ensure your frame accommodates this specific footprint. The integrated -S magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for end-position confirmation. At a 125 mm stroke, the 12 mm rod handles standard loads well, but always minimize lateral side-loading to prevent premature rod-bending and seal wear. Remember that the fixed TPU bumpers only decelerate the stroke end; they do not function as an adjustable air cushion like the MFC variant. For any application requiring the load to stay put during a compressed air failure, install a separate pilot-operated check valve because the standard piston will drift.
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 MF32X125SCMLB FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, it does not conform to ISO 6432 standards, though its JIS round-body design is deliberately shorter than an ISO 6432 cylinder to save space. It uses an LB foot mount and CM round-end cover. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for position sensing.
