About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X270CM
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with a 270 mm stroke. The stainless-steel barrel and Ø12 mm piston rod provide reliable mild corrosion resistance, performing better in damp environments than painted alternatives. Air extends and retracts the rod through a 1/8" port, while fixed TPU bumper pads absorb the impact at each stroke end.
Because the 402.2 N rating is a theoretical maximum, plan for a safe working load of roughly 241 N to account for friction and pressure drops. In vertical lifting scenarios, this translates to hoisting about 20.5 kg safely with a 2:1 margin. The CM round end back cover keeps the rear profile smooth, and since this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X270CM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using its 402.2 N push force to swing packages weighing up to 20 kg onto secondary sorting lanes.
Bearing Press Assembly
Drives a 270 mm stroke to seat bronze bearings into housings on an automated line, relying on fixed TPU pads to soften the end-of-stroke impact.
Pallet Stopper Arm
Deploys a rugged stopping barrier at the end of a roller track, where the stainless build withstands incidental impacts and mildly humid warehouse air.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X270CM the Right Cylinder?
Sizing this 32 mm bore against its neighbours shows a clear power jump: it steps up from the 25 mm class (245.3 N push @0.5 MPa) and sits just below the 40 mm class (628.3 N push @0.5 MPa). The 270 mm stroke is well within the 500 mm standard limit, though at this extension the Ø12 mm rod requires careful alignment to prevent side-loading and premature seal wear. The 1/8" port and M10x1.25 male rod thread are fixed by the bore size.
Note that venting or centering the directional valve causes the piston to drift, as the fixed TPU pads only decelerate the end of travel rather than locking the load. To suspend a weight securely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/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/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI25~40 Stainless Steel Mini Cylinder MI32X270CM FAQ
This 32 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG or EMSG switches. You would need the -S variant for reed or solid-state sensing. The unit uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion.
