Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150UTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm 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 MF40X150UTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore cylinder handles heavy-duty positioning in tight fixtures. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 150 mm stroke, it saves valuable mounting length without sacrificing power. The SUS304 stainless barrel and riveted aluminium covers naturally resist mild corrosion and washdown environments.
Built for reliable end-of-stroke deceleration, the fixed TPU bumper pads and front-cover anti-impact pad soften impact without offering adjustable cushioning. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which means it can vertically lift about 32 kg against gravity. Air connects via a 1/4 inch port, and the piston's two-way seal retains an oil film for extended mechanical life.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150UTC Is Used
Pallet Diverter Gate
Shifts heavy pallets onto secondary packaging lines using the full 628.3 N push force, while the compact JIS body fits neatly within the conveyor frame width.
Press Fit Bushings
Pushes bronze bushings into automotive housings on an assembly line, relying on the fixed TPU bumper pads to absorb the sudden resistance at the end of the 150 mm stroke.
Vertical Carton Flap Folder
Folds heavy corrugated carton flaps downward during case packing, safely lifting components weighing up to 32 kg with a two-to-one safety margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X150UTC the Right Cylinder?
When sizing this 40 mm bore unit, step down to the MF32 if your task requires only 402.2 N of push force at 0.5 MPa, as the 40 mm bore is the largest available in the MF series. If your mechanism must hold a vertical load mid-stroke, remember that venting the air or centering the valve will cause the piston to drift downward; the bumper pads only soften the end of travel and act as neither a brake nor a lock. You must fit an external pilot-operated check valve or a dedicated rod lock to secure the payload safely.
This specific configuration includes a U flat-end rear cover and a TC trunnion mount for pivoting frames. Because it lacks the -S suffix, this SKU cannot accept CMSG, DMSG, or EMSG magnetic sensors; you must select an -S variant if your control system requires position detection. The 150 mm stroke is well within standard limits, but ensure your TC mounting blocks are perfectly aligned to prevent side-loading and premature rod-bending wear.
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 MF40X150UTC FAQ
This 40 mm bore double-acting cylinder features a 1/4 inch air port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need an MF40X150UTC-S variant for position sensing. It includes a U flat-end back cover and a TC trunnion mount that allows the cylinder body to pivot, and its JIS-standard round-body design is shorter than an ISO 6432 cylinder to save mounting space.
