About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X175SR
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 provide mild corrosion resistance, offering a distinct advantage over painted alternatives in damp or washdown environments. It features a 1/8" port and an R back cover with an axial-in port orientation for streamlined plumbing.
Fixed TPU bumper pads decelerate the piston at both stroke ends, softening impacts without the complexity of adjustable cushioning. The built-in magnet (-S) directly supports CMSG, DMSG, and EMSG switches for precise position detection. 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.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X175SR Is Used
Product Diverting Gate
Actuates heavy routing flaps on packaging lines, using its 402.2 N push force to reliably shift boxed goods weighing up to 20 kg onto secondary belts.
Washdown Clamp Station
Secures stainless steel fittings during high-pressure rinsing in food processing, where the cylinder's own corrosion-resistant barrel withstands ambient moisture.
Pallet Stopper Arm
Deploys a 175 mm stroke to halt incoming pallets at a loading station, absorbing the impact via fixed TPU bumper pads rather than transferring shock to the assembly.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X175SR the Right Cylinder?
When sizing this 32 mm bore, compare it against adjacent options: the smaller Ø25 generates 245.3 N of push at 0.5 MPa, while the larger Ø40 provides 628.3 N. This model sits comfortably in the mid-to-heavy range. The 175 mm stroke is well within the 500 mm maximum standard stroke, keeping the unit readily available without made-to-order delays. For mounting flexibility, it supports LB foot, FA flange, SDB pivot, and TC trunnion brackets alongside its R rear cover.
Because the fixed TPU bumpers only decelerate the stroke end and provide no holding force, the piston will drift if air pressure is lost or the valve is centered. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. Additionally, on a 175 mm stroke, ensure the rod end is guided properly to prevent excessive side-loading and premature rod bending.
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 MI32X175SR FAQ
This 32 mm bore cylinder features a 1/8" 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, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To maintain a vertical position, you must install an external rod lock or a pilot-operated check valve.
