Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75UTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MF40X75UTC
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X75UTC is a robust 40 mm bore double-acting round-body cylinder built to JIS standards. 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 extended mechanical life. Because this JIS body is physically shorter than a comparable ISO 6432 cylinder for the same 75 mm stroke, it provides a tangible packaging advantage in tight machinery layouts.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke-end impact is reliably decelerated. Plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. This specific SKU lacks the -S magnet and therefore cannot accept CMSG, DMSG, or EMSG position switches. Air connects via a 1/4 inch port, and the male rod thread is M14x1.5.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75UTC Is Used
Package Diverting
Actuates routing gates on packaging lines, using the 628.3 N thrust to push heavy cartons onto auxiliary belts at high cycling speeds.
Vertical Pressing
Applies downward clamping pressure for assembly fixtures, safely handling components weighing up to 32 kg with a 2:1 safety margin.
Material Handling
Drives short-stroke product ejectors in automated manufacturing cells where the compact JIS body length conserves valuable floor space.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75UTC the Right Cylinder?
When sizing this 40 mm bore actuator, compare it directly against its neighbours: the MF32 provides 402.2 N of push at 0.5 MPa, while the MF40X75UTC steps up to 628.3 N. As 40 mm is the largest available MF bore, moving beyond this capacity requires adopting a different cylinder family. For your mounting scheme, this unit pairs with a TC trunnion and features a U flat-end back cover. If your mechanism demands position feedback, you must select the -S magnet variant, as this standard configuration cannot host a reed or solid-state sensor.
Remember that a basic double-acting cylinder drifts when air pressure is removed or the control valve is centred; the internal bumpers only soften the end of travel and act as neither a brake nor a holding lock. To suspend a vertical load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock mechanism. Furthermore, on this 75 mm stroke, ensure the load is guided to prevent rod bending and premature seal 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 MF40X75UTC FAQ
The 40 mm bore double-acting MF40X75UTC 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, with a theoretical maximum of 128.1 kgf at 1.0 MPa. It uses a 1/4 inch air port and an M14x1.5 male rod thread.
This specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must specify the -S variant for sensing. Dimensionally, the JIS-standard riveted stainless body is shorter than an ISO 6432 cylinder of the same bore and stroke, saving mounting length. It features fixed TPU bumper pads rather than an adjustable air cushion.
