Airtac MF32-40 Stainless Steel Mini Cylinder MF32X155SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X155SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 155mm 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 MF32X155SCA
Generating 402.2 N of push force at 0.5 MPa, this double-acting AirTAC MF32X155SCA mini cylinder features a 32 mm bore and a 155 mm stroke. The JIS-standard round-body construction pairs a SUS304 stainless steel barrel with riveted aluminium covers, yielding a total footprint that is physically shorter than a comparable ISO 6432 cylinder to save valuable mounting length. Its piston relies on a heterogeneous two-way seal that retains an oil film for extended lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts.
Equipped with a built-in piston magnet (-S), this unit supports CMSG, DMSG, and EMSG reed or electronic sensors for position detection. The CA back cover provides a rear pivot mount. 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. Air connects via a 1/4" port, and the 12 mm rod features an M10x1.25 male thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X155SCA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 402.2 N push force to redirect medium-weight cartons onto secondary tracks.
Clamp Arm Actuation
Extends a pivoting clamp arm on a CNC machining fixture, where the CA rear pivot accommodates slight angular movement during part securing.
Vertical Parts Lift
Raises lightweight material trays in an assembly cell, safely lifting components up to 20.5 kg thanks to a calculated 2:1 safety margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X155SCA the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 reduces the 0.5 MPa push force to 245.3 N, whereas stepping up to the MF40 increases it to 628.3 N. This model occupies the middle ground, effectively bridging the gap for medium-duty tasks. The CA rear pivot cover is ideal for applications requiring angular alignment during the stroke. Because the standard -S magnet enables switch tracking, you can easily integrate CMSG or DMSG sensors along the SUS304 barrel.
Keep in mind that a standard double-acting cylinder drifts if air pressure drops or the valve is centred, as the internal bumpers only decelerate the stroke end rather than locking the load. To suspend a vertical weight safely, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit. At 155 mm, verify your guiding structure to prevent rod bending under side loads.
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 MF32X155SCA FAQ
This 32 mm bore double-acting cylinder delivers 402.2 N push and 345.6 N pull at 0.5 MPa, and 563 N push and 483.8 N pull at 0.7 MPa. Its theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is 1/4".
The JIS-standard round-body design is shorter than an ISO 6432 cylinder of the same bore and stroke, saving mounting space. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. The SUS304 stainless barrel resists mild corrosion, and the -S magnet allows for CMSG or DMSG sensor integration.
