Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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 MF40X10SUTC
Generating 628.3 N of push force at 0.5 MPa, this double-acting AirTAC mini cylinder handles heavy-duty clamping in tight spaces. The JIS-standard round-body design is physically shorter than an ISO 6432 cylinder for the same 40 mm bore and 10 mm stroke, delivering a tangible packaging advantage. A built-in piston magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG sensors for position confirmation.
The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock, while the two-way piston seal retains an oil film for long service life. Plan for roughly 377 N of actual work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SUTC Is Used
Heavy-Duty Stamping Press
Provides 628.3 N of brief, high-force clamping at 0.5 MPa to hold sheet metal blanks securely in place during a stamping cycle.
Pallet Diverting Gate
Uses the short 10 mm stroke and TC trunnion mount to actuate a heavy redirect gate for routing loaded pallets on a packaging line.
Roller Brake Mechanism
Applies immediate stopping force to gravity conveyor rollers, using the U flat-end rear cover to absorb static reaction loads.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SUTC the Right Cylinder?
Choosing this 40 mm bore provides maximum thrust for the MF series, stepping up from the 32 mm bore that yields 402.2 N at 0.5 MPa. Since 40 mm is the largest available MF bore, verify that 628.3 N is sufficient, as there is no larger standard size. The included TC trunnion mount pairs with the U flat-end back cover for pivoting loads, and the 1/4" port accommodates the required airflow. Because the stroke is only 10 mm, side-load stress on the 16 mm rod is minimal.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the bumpers only soften the end of travel and do not function as a brake. To suspend a load safely during an outage, install 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 MF40X10SUTC FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod 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.
Yes, the -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG switches. It is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting length without claiming ISO compliance.
