Airtac MF32-40 Stainless Steel Mini Cylinder MF32X115SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X115SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 115mm 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 MF32X115SCM
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting actuator uses a SUS304 stainless barrel and riveted aluminium covers to resist mild washdown. The riveted rolling-packed structure keeps the overall body shorter than a comparable ISO 6432 cylinder, saving valuable mounting length in tight fixtures. A built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG switches, while the round-end CM back cover simplifies rear pivot mounting.
The internal piston relies on a heterogeneous two-way seal that retains an oil film for long service life. Fixed TPU bumper pads and a front-cover anti-impact pad work together to soften stroke-end impact, though they decelerate rather than provide adjustable cushioning. For real-world work at 0.5 MPa, plan for about 241 N of usable load, which translates to lifting roughly 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X115SCM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 115 mm stroke to redirect cartons into secondary lanes with 402.2 N of push force.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, where the round-end CM back cover pivots to accommodate slight misalignment during clamping.
Vertical Parts Lift
Raises lightweight component trays weighing up to 20.5 kg between assembly tiers, relying on the built-in magnet to trigger DMSG descent sensors.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X115SCM the Right Cylinder?
When sizing this 115 mm stroke unit, consider the MF25 if your load only requires 245.3 N of push at 0.5 MPa, or step up to the MF40 for 628.3 N if heavier forces are needed. Because this specific SKU includes the S suffix, it arrives magnet-ready for position sensing. If your process drops air pressure or centres the valve, the piston will drift; the bumpers only soften the end of travel, so add an external rod lock or pilot check valve to hold a suspended load. At 115 mm, ensure your mounting arrangement—whether LB foot, FA flange or TC trunnion—prevents rod side-loading and bending.
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 MF32X115SCM 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, with a theoretical maximum of 82 kgf at 1.0 MPa.
It features a JIS-standard round-body design with a SUS304 stainless barrel and riveted aluminium covers, making the body shorter than an ISO 6432 equivalent. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and the included magnet supports CMSG, DMSG and EMSG sensors.
