Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 70mm 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 MF32X70SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers. The MF32X70SCM variant includes a piston magnet for position sensing and a CM round-end rear cover. Its JIS-standard round body is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length in tight machinery.
The piston relies on a two-way oil-retaining seal for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. For practical sizing, plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Air connects via a 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SCM Is Used
Package Diverting
Actuates a routing gate on a packaging line, using the 402.2 N push force to redirect cartons weighing up to 20 kg at speeds up to 800 mm/s.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, where the compact JIS body length saves Z-axis height compared to standard ISO cylinders.
Component Insertion
Presses bearings into housings on an assembly machine, relying on the built-in magnet and DMSG sensors to confirm proper insertion depth.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SCM the Right Cylinder?
If 245.3 N from the MF25 bore is insufficient, this 32 mm option provides a solid step up; should you need substantially more thrust, the MF40 offers 628.3 N at 0.5 MPa. Because the -S magnet is present, you can directly mount CMSG, DMSG, or EMSG reed or electronic switches for end-of-stroke detection.
Remember that standard double-acting cylinders drift when air pressure is lost or the valve is centred. The fixed bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. With a 70 mm stroke, side-load and rod-bending forces are minimal, but always ensure the load axis aligns with the M10x1.25 male rod thread.
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 MF32X70SCM 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.
It features a JIS-standard round-body design that is shorter than an ISO 6432 cylinder of the same bore and stroke, saving mounting space. The CM round-end rear cover aids pivot mounting. Stroke deceleration is handled by fixed TPU bumper pads, not an adjustable air cushion.
