Airtac MF32-40 Stainless Steel Mini Cylinder MF40X800SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X800SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 800mm 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 MF40X800SCM
Generating 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore cylinder handles demanding 800 mm reach tasks. The 800 mm stroke exceeds the 500 mm standard limit, making this specific SKU a non-standard, made-to-order configuration engineered for extended travel. Its JIS-standard round-body construction is notably shorter than an ISO 6432 cylinder of the same bore and stroke, yielding a tangible packaging advantage in tight machine layouts.
The SUS304 stainless steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown environments. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact, though they decelerate rather than provide adjustable cushioning. Because the code contains an S, it includes a piston magnet for CMSG, DMSG, or EMSG switches, and the CM suffix denotes a round-end rear cover. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 32 kg vertically.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X800SCM Is Used
Extended Transfer Pushing
Shunting heavy pallets or chassis frames along a 800 mm conveyor bed, utilising the 628.3 N push force to overcome friction over a long travel distance.
Vertical Material Elevation
Hoisting 32 kg component trays between floor levels in a packaging line, where the 800 mm stroke provides the necessary vertical displacement.
Large Door Actuation
Opening and closing heavy industrial machine guard doors on automated welding cells, relying on the round-end CM rear cover for pivot mounting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X800SCM the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task requires less force, as the 32 mm variant outputs 402.2 N at 0.5 MPa. Since 40 mm is the largest available bore in the MF series, exceeding 628.3 N at 0.5 MPa requires ganging multiple cylinders or migrating to a larger profile series. The 1/4 inch port and M14x1.5 male rod thread are fixed to this bore. At 800 mm, the extended stroke amplifies rod bending moments, so strict lateral load alignment is critical to prevent premature seal wear.
This unit lacks a position lock; if air pressure drops or the valve centres, the piston will drift and the TPU pads only soften the end of travel. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock. The built-in magnet allows seamless CMSG or DMSG sensor integration for end-of-stroke confirmation.
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 MF40X800SCM FAQ
This 40 mm bore cylinder features a 1/4 inch air port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the TPU bumper pads only decelerate the piston near the stroke end and act as neither a brake nor a lock. The piston will drift on air loss, so an external rod lock or pilot check valve is required to hold a suspended load. The JIS-standard round body is also shorter than an ISO 6432 cylinder, saving mounting length.
