Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 150mm 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 MF32X150SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X150SU is a double-acting JIS-standard round-body mini cylinder built for tight fixture layouts. For the same 32 mm bore and 150 mm stroke, its riveted rolling-packed body is physically shorter than an ISO 6432 cylinder, giving you a tangible packaging advantage. The SUS304 stainless steel barrel and aluminium covers shrug off mild washdown environments, while the piston's two-way seal retains an oil film for long service life.
This specific SKU includes a built-in piston magnet for position sensing and features a U-style flat-end rear cover. The fixed TPU bumper pads and front-cover anti-impact pad soften the stroke-end impact by decelerating the piston. Based on the 402.2 N output, you can plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread handle the required airflow and mounting loads.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SU Is Used
Package Diverting Gate
Actuates a routing flap on a 300 mm belt conveyor, using the 402.2 N thrust to push medium-weight cartons into a sorting lane.
Clamp Station
Secures aluminium extrusions in a CNC machining fixture, where the shorter JIS body prevents interference with the spindle.
Vertical Parts Lift
Raises 20 kg component trays between processing tiers, relying on the U flat-end cover for stable rear frame mounting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150SU the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: step down to an MF25 for 245.3 N at 0.5 MPa, or move up to an MF40 if you need 628.3 N. The MF32X150SU strikes a middle ground for medium-force tasks. Because the standard U flat-end cover and fixed bumpers only decelerate the stroke end, they cannot hold a load if air pressure drops or the valve is centred—the piston will drift. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve. At 150 mm, this stroke is well within the 500 mm standard limit, but always guide the rod to prevent side-load bending.
The -S suffix means you can mount CMSG, DMSG, or EMSG reed or electronic switches directly onto the stainless body for precise end-of-stroke detection. You can adapt the cylinder to various frames using LB foot, FA flange, SDB pivot, or TC trunnion hardware.
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 MF32X150SU FAQ
The 32 mm bore generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/4" air port and an M10x1.25 male rod thread.
No, the MF does not conform to ISO 6432 standards. It is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 unit for the same bore and stroke. It uses fixed TPU bumper pads rather than an adjustable air cushion, and this SKU includes the -S magnet for CMSG/DMSG/EMSG sensors.
