About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X220CM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X220CM is a double-acting round-body mini cylinder built for mid-weight automation. Its stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it highly suitable for damp production areas where painted steel quickly degrades. The 220 mm stroke operates at speeds between 30-800 mm/s, regulated through a 1/8 inch port, and the CM round end cover provides a clean, compact rear profile for straightforward mounting.
Because the fixed TPU bumper pads only decelerate the piston near the stroke end rather than locking it in place, you should plan for a safe working load of roughly 241 N. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors; you would need the -S variant for position feedback.

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 MI32X220CM Is Used
Package Diverting Gate
Actuates a routing flap on a logistics conveyor to push 15 kg cartons onto a secondary packing line, utilising the 402.2 N push force to overcome side friction.
Textile Loom Tensioner
Maintains consistent tension on heavy fabric webs in a humid dyeing facility, where the stainless-steel construction prevents rust from ambient moisture.
Pallet Stacking Pusher
Extends 220 mm to square up cardboard pallets before stretch wrapping, relying on the CM round end cover for stable rear mounting against the machine frame.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X220CM the Right Cylinder?
When sizing this 32 mm bore, the smaller Ø25 MI generates 245.3 N of push at 0.5 MPa, while the larger Ø40 MI pushes 628.3 N, giving you clear scaling options if this 402.2 N model is borderline. The 220 mm stroke is well within the 500 mm maximum standard stroke for this bore, so no made-to-order lead time is required. Keep in mind that a plain MI cylinder will drift and drop its load if air pressure is lost or the valve is centered; the TPU bumpers only soften the end-of-stroke impact and act purely as a decelerator, never as a brake. For vertical or suspended loads that must hold position, 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 MI32X220CM FAQ
This 32 mm bore cylinder features a 1/8 inch air port and a Ø12 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, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant of the MI series to enable magnetic position sensing. The unit uses fixed TPU bumper pads to decelerate the stroke end, rather than an adjustable air cushion.
