About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100R
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X100R is a robust double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and piston rod shrug off mild corrosion, making it highly suitable for damp production environments where painted steel quickly degrades. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb impact energy at the stroke ends to protect your machinery.
This 32 mm bore, 100 mm stroke model features a 1/8" port and an R-type back cover with an axial-in port orientation for straightforward plumbing. Because it lacks the -S suffix, this specific SKU cannot accept magnetic position switches; you would need the -S variant to mount CMSG, DMSG or EMSG sensors. For practical sizing, plan for a safe working load of roughly 241 N, which equates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100R Is Used
Stamping Pin Ejection
Uses the 402.2 N push force to reliably eject stamped metal pins from a die, absorbing the shock of repeated impact with its fixed TPU bumpers.
Heavy Package Diverting
Deploys the 100 mm stroke to push heavier cartons across a transfer plate, where the stainless rod withstands incidental washdown during facility cleaning.
Pallet Stopper Gate
Acts as a robust pneumatic stop for loaded pallets on a gravity roller track, dropping down to halt 20 kg loads without bouncing back.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100R the Right Cylinder?
When sizing this 402.2 N (at 0.5 MPa) unit, compare it against its neighbours: the Ø25 bore provides 245.3 N of push, while the larger Ø40 bore yields 628.3 N. This Ø32 model hits a strong middle ground for heavier tooling. Note that a standard double-acting cylinder like this will drift if air pressure is lost or the valve is centered—the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock.
The R back cover supplies a convenient axial-in port, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion mounts to fit your frame. Remember that this base configuration has no internal magnet, so it cannot host sensing switches without upgrading to the -S version. If your application requires adjustable end-cushioning rather than fixed bumpers, step up to the MIC 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 MI32X100R FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, because this model lacks the -S suffix, it has no internal magnet and cannot host CMSG, DMSG, or EMSG switches. You must select the -S variant for position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration, not an adjustable air cushion.
