Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCA 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 MF40X650SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty actuation within a compact footprint. Because the SUS304 stainless barrel and riveted aluminium covers form a shorter body than an equivalent ISO 6432 unit, it saves valuable mounting length in tight machinery. The 650 mm stroke exceeds the 500 mm standard limit, making this a made-to-order configuration. It features a 1/4" port, an M14x1.5 male rod thread, and a CA pivot back cover.
The piston relies on a heterogeneous two-way seal that retains an oil film for prolonged lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts without offering adjustable cushioning. Plan for roughly 377 N of actual work at 0.5 MPa, or expect it to lift about 32 kg vertically with a 2:1 safety margin. The integrated -S magnet enables CMSG, DMSG, or EMSG switches for position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCA Is Used
Pallet Diversion Arm
Swings a heavy diverter gate on a packaging conveyor, utilising the CA pivot mount to absorb angular stress while pushing loads with 628.3 N at 0.5 MPa.
Vertical Carton Flap Folder
Reaches deep across a 650 mm carton width to fold heavy corrugated flaps, where the shorter JIS body prevents collision with adjacent overhead rollers.
Material Lift Gate Actuator
Elevates a loaded transfer chute, safely lifting approximately 32 kg of metal components vertically with a 2:1 safety margin at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X650SCA the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task requires only 402.2 N of push at 0.5 MPa, as the 40 mm bore is the largest available in the MF series. For this non-standard 650 mm stroke, be mindful of rod bending under side loads and ensure rigid guidance along the extended rod. The CA pivot back cover is ideal for accommodating slight misalignments in pivoting mechanisms.
Remember that standard double-acting operation means the piston will drift if air pressure is lost or the valve is centred; the bumpers only decelerate the stroke end and do not function as a braking lock. To suspend a load safely during an air loss event, incorporate an external pilot-operated check valve or a dedicated rod lock.
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 MF40X650SCA FAQ
This 40 mm bore cylinder features a 1/4" air 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 force of 128.1 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The 650 mm stroke is a made-to-order non-standard length, as it exceeds the 500 mm maximum standard stroke for this bore.
