About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450SCM
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 Ø12 mm piston rod resist mild corrosion, making it highly suitable for damp production areas where painted steel alternatives degrade. A built-in piston magnet (-S) allows seamless integration with CMSG, DMSG, or EMSG reed and electronic switches for precise position detection.
Equipped with fixed TPU bumper pads, the unit decelerates the stroke end effectively without the complexity of adjustable cushioning. The 1/4" port supplies ample airflow for the 30-800 mm/s speed range. For practical sizing, plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The CM round end cover completes the rear assembly, offering a clean, versatile mounting orientation for your machinery.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450SCM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to redirect dense cartons reliably at high cycling speeds.
Pallet Stacking Pusher
Extends 450 mm to push layered product rows onto a palletizing station, with the stainless build enduring humid warehouse environments.
Textile Loom Tensioner
Drives a fabric tensioning bar inside a textile machine, relying on the CM round end cover for secure rear mounting and the -S magnet for stroke tracking.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450SCM the Right Cylinder?
When sizing this 32 mm bore, evaluate the neighbouring capacities: step down to a Ø25 bore (245.3 N push at 0.5 MPa) for lighter duties, or step up to a Ø40 bore (628.3 N push at 0.5 MPa) if your payload exceeds the safe working threshold. The 450 mm stroke operates within the 500 mm maximum standard limit, though at this extended length you must carefully manage side loading to prevent premature rod bending and seal wear. The CM round back cover provides a specific rear profile for your mounting geometry.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred; the TPU bumpers only soften the impact at stroke extremes and do not function as a braking lock. If your application requires strict position holding under load, integrate an external rod lock or a pilot-operated check valve into the 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 MI32X450SCM FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. 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, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not act as a lock. For vertical loads, you must install an external rod lock or a pilot-operated check valve.
