Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CATC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CATC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 50mm 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 MF40X50CATC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning in tight spaces. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 50 mm stroke, it saves valuable mounting length. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact without offering adjustable cushioning.
For practical sizing, plan for roughly 377 N of real work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. Air enters via a 1/4 inch port to drive the 16 mm rod. This specific CA and TC configured SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; choose an -S variant if position feedback is required.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CATC Is Used
Press Fit Subassembly
Drives a 32 kg bearing housing into a machining fixture, utilising the 628.3 N push force at 0.5 MPa to seat components firmly without external hydraulics.
Pallet Divert Arm
Swings a heavy transfer gate on a packaging line using the CA pivot back cover and TC trunnion mount, withstanding repeated impacts via the fixed TPU bumper pads.
Washdown Gate Actuator
Shifts a stainless-steel diverter flap in a food-grade washdown zone, relying on the SUS304 barrel and riveted aluminium covers to resist moisture and mild corrosion.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CATC the Right Cylinder?
When sizing this 40 mm bore, compare it directly with the smaller MF32, which provides 402.2 N of push at 0.5 MPa. If your fixture requires less force, the 32 mm option saves space, but since 40 mm is the largest available MF bore, there is no larger standard alternative for loads exceeding 628.3 N. The included TC trunnion and CA pivot rear cover suit articulated and swing-mount installations.
Remember that a standard cylinder drifts when air is removed or the valve is centred, as the bumpers only decelerate the stroke end rather than locking the rod. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Furthermore, this non-magnetic version cannot host reed or solid-state switches.
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 MF40X50CATC FAQ
The 40 mm bore double-acting cylinder uses a 1/4 inch port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 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.
The MF is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 model for the same stroke, so you must use its own LB, FA, SDB, or TC trunnion mounts. This specific SKU has no internal magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to an -S version.
