Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150U 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 MF32X150U
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles mid-weight automation tasks with ease. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 150 mm stroke, it saves valuable mounting length in tight machinery.
The internal piston relies on a two-way oil-retaining seal to maintain lubrication for a long service life. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact, though they decelerate rather than provide an adjustable cushion. 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 MF32X150U Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 150 mm stroke to redirect mid-weight cartons at high speed.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, delivering 402.2 N of push at 0.5 MPa to hold parts firmly for drilling.
Vertical Parts Lift
Raises small material trays in an assembly cell, safely lifting loads up to 20.5 kg thanks to a 2:1 safety margin on the 0.5 MPa output.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X150U the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N at 0.5 MPa, while the larger MF40 steps up to 628.3 N at 0.5 MPa. This MF32X150U uses a 1/4" port and an M10x1.25 male rod thread. It features a U flat-end back cover and operates at speeds between 30-800 mm/s.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Note that a plain cylinder drifts when air is lost or the valve is centred; the bumper pads only soften the stroke end and do not act as a brake. To hold a load securely, add an external rod lock or a pilot-operated check valve.
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 MF32X150U FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It also uses a U flat-end back cover and is shorter than an ISO 6432 cylinder for the same stroke.
