About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160SR
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding actuation tasks. The stainless-steel barrel and piston rod supply mild corrosion resistance, making it well-suited for damp or washdown environments where painted alternatives degrade. A built-in piston magnet (-S) enables position sensing with CMSG, DMSG or EMSG switches, while the R back cover provides an axial-in port orientation for tight spatial constraints. Fixed TPU bumper pads absorb stroke-end impacts to protect the mechanism.
With a 160 mm stroke and a 1/8" air port, this riveted construction actuator is designed for substantial travel. 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. In a vertical lift setup, this translates to hoisting approximately 20.5 kg safely with a two-to-one margin, ensuring the cylinder moves real part weights without overstressing.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160SR Is Used
Package Diverting Gate
Actuates a routing flap on a logistics sorting line, using the 402.2 N push force to reliably redirect heavy cartons at high speeds.
Vertical Parts Lift
Raises lightweight metal stampings in a transfer press, safely lifting components up to 20.5 kg with a two-to-one safety margin.
Clamp Actuation
Secures automotive housings during machining operations, leveraging the 160 mm stroke to clear the work zone completely before tool engagement.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160SR the Right Cylinder?
When sizing this 32 mm bore actuator, compare it against its neighbours: a 25 mm bore provides 245.3 N of push at 0.5 MPa, while stepping up to a 40 mm bore yields 628.3 N. This model hits a strong middle ground for medium-force automation. The 160 mm stroke is well within the 500 mm maximum standard limit, but at this length side-load forces can induce rod bending, so ensure proper load alignment or use a guide rail. Because the R back cover features an axial-in port, verify your manifold orientation matches this layout.
Note that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred, as the fixed TPU bumpers only decelerate the stroke end and do not function as a mechanical brake. If your application requires strict position holding under load loss, 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 MI32X160SR FAQ
This 32 mm bore cylinder features a 1/8" air port and a Ø12 mm piston 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, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a locking brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
