Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCASDB
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCASDB is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MF40X200SCASDB
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting JIS-standard round-body mini cylinder handles heavy-duty actuation within tight machinery envelopes. For the same 200 mm stroke, the riveted SUS304 stainless steel and aluminium body is physically shorter than a comparable ISO 6432 unit, providing a tangible packaging advantage. The integrated piston magnet (-S) supports CMSG, DMSG, and EMSG switches for precise end-of-stroke detection.
Built for demanding environments, the SUS304 barrel shrugs off mild corrosion and washdown while the two-way oil-retaining seal ensures long-term lubrication. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts without offering adjustable cushioning. When lifting vertically, plan for a safe working load of about 377 N, which means it can lift roughly 32 kg with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic plumbing for high-flow cycles.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCASDB Is Used
Pallet Diverter Gate
Swings heavy diverter arms on packaging lines, using the 628.3 N thrust to push loaded pallets onto secondary conveyors without stalling.
Stamping Press Feed
Drives a robust material pusher into a metal stamping press, where the 200 mm stroke loads blanks accurately under high-speed cycling.
Vertical Parts Lift
Elevates 30 kg hardware totes between conveyor tiers, safely operating within the calculated 32 kg vertical lift capacity at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCASDB the Right Cylinder?
Choosing this 40 mm bore makes sense when the smaller MF32 (offering 402.2 N at 0.5 MPa) lacks the necessary thrust, as stepping up here yields 628.3 N of push force. Since 40 mm is the largest available MF bore, moving beyond this capacity requires a different cylinder family entirely. The included SDB pivot-block mounting pairs with the CA rear pivot cover to handle angular misalignment during stroke transitions. Because the 200 mm stroke amplifies leverage forces, ensure your front-end tooling is guided to prevent rod bending and premature seal wear.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a mechanical brake. If air pressure drops or the directional valve is centred, the rod will drift and drop any suspended mass. To secure a vertical load safely, install an external pilot-operated check valve or a dedicated pneumatic 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 MF40X200SCASDB FAQ
This 40 mm bore model features a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push increases to 879.6 N and the pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
It uses a JIS-standard round-body design with a SUS304 stainless barrel and riveted aluminium covers, making it shorter than an ISO 6432 cylinder for the same 40x200 dimensions. It includes an SDB pivot block and a CA back cover for pivoting mounts. The -S suffix denotes a built-in magnet for CMSG, DMSG, or EMSG sensors.
