Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 135mm 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 MF32X135SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting AirTAC MF32X135SCA mini cylinder is built around a JIS-standard round body. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the piston's two-way seal retains an oil film for long operational life. Because the MF envelope is shorter than an ISO 6432 cylinder for the same 32 mm bore and 135 mm stroke, it saves valuable mounting length in tight machinery.
This specific SKU includes a built-in piston magnet for position sensing and a CA rear pivot cover. The fixed TPU bumper pads and front-cover anti-impact pad soften stroke-end impact by decelerating the piston. For practical sizing, plan for about 241 N of real work at 0.5 MPa, which means it can safely lift a 20.5 kg vertical load with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCA Is Used
Textile Loom Doffing
Actuates the doffing rail on automated weaving machines, where the compact JIS body fits within narrow frame gaps and the 402.2 N force reliably shifts full yarn bobbins.
Package Lane Diverting
Pivots a sorting deflector gate using the CA rear mount to route medium-weight cardboard cartons, benefiting from the 20.5 kg safe vertical lift equivalent.
Welding Fixture Clamping
Holds steel brackets in a robotic weld cell; the SUS304 barrel withstands coolant splash while the -S magnet confirms clamp position via a DMSG sensor.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X135SCA the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N of push force at 0.5 MPa, while the larger MF40 steps up to 628.3 N, allowing you to bracket your exact load requirements. This model's 1/4" port and M10x1.25 male rod thread match the standard 32 mm bore specification. The included CA pivot back cover suits articulated rod-end loads, and the -S magnet enables CMSG, DMSG, or EMSG switches for end-of-stroke confirmation.
Remember that the fixed TPU bumpers only decelerate the stroke end; they do not function as a lock. If your application must prevent drift on air loss or a centred valve, you will need an external rod lock or a pilot-operated check valve. At 135 mm, this stroke is well within the 500 mm standard limit, but always ensure the rod-end alignment minimizes side-load 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 MF32X135SCA FAQ
The 32 mm bore features a 1/4" port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, the MF is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 unit, so it does not conform to ISO 6432 mounting. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion; choose the MFC variant if you need adjustable cushioning.
