Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MF40X100SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles demanding compact automation tasks. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which means it lifts roughly 32 kg vertically with a 2:1 safety margin.
Because the riveted rolling-packed structure is inherently compact, the overall body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 100 mm stroke, yielding a tangible packaging win in tight fixtures. The unit includes a built-in piston magnet for position sensing and features a CM round-end rear cover. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact, operating at speeds from 30-800 mm/s via the 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCM Is Used
Carton Diverter Arms
Actuates heavy routing flaps on high-speed packaging lines, using the 628.3 N push force to positively shift loaded corrugated cartons between merging belts.
Press Fit Subassembly
Drives small bushings or bearings into aluminium housings on an automated machining cell, relying on the fixed TPU pads to absorb the 100 mm stroke impact.
Pallet Stop Gates
Controls heavy pallet flow on roller conveyors, where the SUS304 stainless barrel withstands intermittent washdown and the CM round-end cover pivots smoothly.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCM the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which provides 402.2 N. Since 40 mm is the largest available MF bore, exceeding this capacity requires a different cylinder family. To match your fixture, choose from LB foot, FA flange, SDB pivot, or TC trunnion mounts.
The included magnet (-S) supports CMSG, DMSG, or EMSG switches for end-of-stroke confirmation. Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU pads only decelerate the stroke end and do not function as a brake. Use an external rod lock or pilot check valve for secure load holding.
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 MF40X100SCM FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. The double-acting thrust is 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.
It does not conform to ISO 6432, though its riveted JIS round-body design is deliberately shorter than an ISO 6432 cylinder for the same stroke, saving mounting length. The built-in magnet (-S) allows you to mount CMSG, DMSG, or EMSG switches directly on the SUS304 barrel for position detection.
