Airtac MF32-40 Stainless Steel Mini Cylinder MF40X310SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X310SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 310mm 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 MF40X310SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight machinery envelopes. For the same 40 mm bore and 310 mm stroke, the riveted rolling-packed SUS304 stainless barrel and aluminium covers create a body notably shorter than an ISO 6432 unit, yielding a real packaging advantage. The piston relies on a heterogeneous two-way seal that retains an oil film for prolonged lifespan, while fixed TPU pads and a front-cover anti-impact pad soften stroke-end impacts.
Equipped with a built-in magnet for CMSG, DMSG, or EMSG switches, this unit makes position sensing straightforward. Plan for roughly 377 N of actual work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread ensure robust airflow and mounting for demanding cycles.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X310SCM Is Used
Pallet Diverting Gate
Uses the 628.3 N push force to swing heavy pallet transfer gates on high-speed packaging lines without requiring a massive footprint.
Press Die Ejection
Ejects formed sheet metal parts from lower press dies, relying on the 1/4" port for rapid retraction and the fixed TPU pads to absorb impact.
Vertical Carton Flap Folder
Folds heavy corrugated carton flaps on case erecting machines, safely handling the 310 mm stroke while the CM rear cover allows slight alignment pivot.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X310SCM the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MF32 drops the 0.5 MPa push force to 402.2 N, whereas the 40 mm bore remains the largest available in the MF family at 628.3 N. Because standard air pressure will not hold a load if supply drops or the valve centres, you must add an external rod lock or pilot check valve to prevent vertical drift. The CM round-end back cover suits pivot mounting, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets. At 310 mm, the stroke is well within the 500 mm standard limit, but always guide the rod to avoid bending under side loads.
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 MF40X310SCM FAQ
This 40 mm bore cylinder uses a 1/4" 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.
It does not conform to ISO 6432, though its riveted SUS304 stainless body is deliberately shorter than an ISO 6432 unit, saving mounting length. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion. Mounting options include LB, FA, SDB, and TC styles, and the included -S magnet supports CMSG, DMSG, and EMSG sensors.
