Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 650mm 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 MF40X650SCM
Generating a robust 628.3 N of push force at 0.5 MPa, this double-acting AirTAC MF40X650SCM handles heavy-duty positioning tasks with ease. The 40 mm bore JIS-standard round-body design is notably shorter than a comparable ISO 6432 cylinder, delivering valuable space savings in tight machinery layouts. Because the 650 mm stroke exceeds the 500 mm standard maximum, this specific unit is manufactured as a made-to-order configuration.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the cylinder resists mild corrosion and washdown environments. The internal piston relies on a two-way oil-retaining seal for smooth, long-lasting operation, while fixed TPU bumper pads and a front-cover anti-impact pad soften end-of-stroke impacts. For practical sizing, plan for a safe working load of roughly 377 N, which translates to lifting about 32 kg vertically with a 2:1 safety margin. The integrated magnet (-S) enables position sensing, and the unit features a CM round-end rear cover along with a 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCM Is Used
Pallet Diverting Gate
Utilizes the 628.3 N push force to reliably pivot heavy diverter arms on packaging conveyors, redirecting loaded pallets at high speeds.
Stamping Press Feed
Pushes metal blanks into a stamping press with precision, taking advantage of the CM round-end rear cover for pivoting mount clearance.
Vertical Parts Elevator
Lifts approximately 32 kg of automotive components between assembly tiers, relying on the 650 mm stroke to bridge multi-level platforms.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCM the Right Cylinder?
When sizing this 40 mm bore actuator, compare it directly against the smaller MF32, which provides 402.2 N of push force at 0.5 MPa. Since 40 mm is the largest available bore in the MF series, moving up to a larger standard AirTAC line is required if your application exceeds the 879.6 N push capacity at 0.7 MPa. The 650 mm stroke is non-standard and made-to-order, so ensure your mechanical layout accommodates the extended length and provides adequate rod support to prevent side-loading or bending over the long travel distance.
Remember that a standard double-acting cylinder will drift if air pressure drops or the control valve is centred; the TPU bumpers only decelerate the piston near the stroke end and do not function as a braking lock. To suspend a load safely during an air loss event, install an external pilot-operated check valve or a dedicated rod lock. The built-in magnet allows you to mount CMSG, DMSG, or EMSG switches directly onto the groove for precise end-position detection.
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 MF40X650SCM FAQ
The 40 mm bore double-acting cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 879.6 N and the pull to 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and features an M14x1.5 male rod thread.
No, the piston will drift if air pressure is lost or the valve is centred; the fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. For vertical load holding, use an external rod lock or pilot check valve. The JIS-standard SUS304 stainless round-body is shorter than an ISO 6432 unit, and the -S magnet supports CMSG/DMSG/EMSG sensors.
