About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X275SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial workloads within a compact footprint. The stainless-steel barrel and piston rod supply mild corrosion resistance, making it highly suitable for damp manufacturing environments. It uses fixed TPU bumper pads to decelerate the piston at stroke ends, and the built-in magnet (-S) directly supports CMSG, DMSG and EMSG position switches. Equipped with a CM round end cover, it operates at speeds of 30-800 mm/s.
For practical sizing, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa push rating. Alternatively, it can lift a 20.5 kg mass vertically when applying a 2:1 safety margin. The 1/8" port and M10x1.25 male rod thread ensure robust air delivery and secure mechanical attachment for this 275 mm stroke configuration.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X275SCM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to redirect parcels efficiently onto secondary chutes.
Carton Flap Folding
Drives the mechanical folder arms on a corrugated box sealing machine, relying on the 275 mm stroke to clear varying carton widths.
Textile Loom Tensioning
Maintains precise fabric tension by adjusting a guide roller, with the stainless build resisting humid dye-house environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X275SCM the Right Cylinder?
When sizing this 32 mm bore, compare it against adjacent options: the 25 mm bore generates 245.3 N of push at 0.5 MPa, while the larger 40 mm bore provides 628.3 N. If your application experiences air loss or the directional valve centres, this standard cylinder will drift and cannot hold a suspended load—the TPU bumpers only soften the end-of-stroke impact and act purely as a deceleration mechanism, never as a brake. To maintain vertical position safely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. The included CM round end cover offers specific rear mounting and port orientation flexibility for your assembly.
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 MI32X275SCM FAQ
This double-acting cylinder 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. It features a 1/8" air port and a 32 mm bore.
This model has fixed TPU bumper pads that decelerate the stroke end, not an adjustable air cushion; for adjustable cushioning, look at the MIC variant. Because this SKU includes the -S magnet, you can mount CMSG, DMSG or EMSG reed and electronic switches directly to the body.
