About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X75R
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X75R is a robust double-acting round-body mini cylinder built for demanding industrial work. Its stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion and washdown environments better than painted alternatives. The riveted construction remains highly compact, while fixed TPU bumper pads absorb impact energy at the stroke ends. This specific R-suffix configuration features an axial-in rear port to simplify plumbing in tight machinery layouts.
Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG reed switches. For actuation planning, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa push rating. Alternatively, it lifts around 20.5 kg vertically when applying a 2:1 safety margin. The 1/8" port feeds air efficiently to drive the 75 mm stroke at speeds between 30 and 800 mm/s.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X75R Is Used
Package Diverting Gate
Actuates a heavy routing flap on a distribution conveyor, using its 402.2 N push force to swing heavy cardboard cartons into secondary packing lanes.
Press Pin Insertion
Drives a dowel pin into an aluminum housing on an assembly line, relying on the fixed TPU bumpers to absorb the 75 mm stroke-end shock repeatedly.
Pallet Stopping Arm
Deploys a mechanical stop block to halt empty pallets at a strapping station, where the stainless build resists ambient dust and occasional moisture.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X75R the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the Ø25 MI provides 245.3 N of push at 0.5 MPa, whereas stepping up to the Ø40 MI yields 628.3 N. Choose the 32 mm bore when your application demands 402.2 N of push force alongside a 1/8" air supply. The 75 mm stroke is well within the 500 mm maximum, keeping the rod highly stable without significant bending concerns.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only soften the end-of-stroke impact and act purely as decelerators, never as a locking mechanism. To suspend a load safely during an emergency stop, fit an external pilot-operated check valve or a dedicated rod lock. Furthermore, because this base model has no internal magnet, position sensing is impossible without upgrading to the -S variant.
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 MI32X75R FAQ
This 32 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. It generates 402.2 N of push force and 345.6 N of pull force at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include an internal magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the -S variant (MI32X75S) for position sensing. Additionally, its fixed TPU bumper pads only decelerate the stroke end; they do not function as an adjustable air cushion.
