About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X35SU is a double-acting round-body mini cylinder built for demanding compact automation. Its stainless-steel barrel and rod shrug off mild corrosion, making it highly reliable in damp or washdown environments where painted alternatives degrade. The 35 mm stroke operates through a 1/8 inch port, and the U-style 90-degree rear cover provides flexible mounting orientation.
Fixed TPU bumper pads absorb the impact at stroke ends to protect internal components, though they do not act as an adjustable air cushion. 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. Because this SKU includes the -S magnet, it is fully compatible with CMSG, DMSG and EMSG reed or electronic switches for precise position sensing.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35SU Is Used
Clamp Actuation
Drives robust machining clamps holding heavy cast iron engine blocks, utilizing the 402.2 N push force to secure parts against high cutting forces.
Vertical Parts Press
Pushes lightweight bearing housings into jigs on an assembly line, safely handling loads under the 20.5 kg vertical lift threshold.
Diverter Gate
Pivots a stainless-steel deflector gate on a food-grade conveyor, where the corrosion-resistant construction survives frequent washdowns.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35SU the Right Cylinder?
When sizing this 32 mm bore, compare it against its neighbours: a 25 mm bore yields 245.3 N of push at 0.5 MPa, while stepping up to a 40 mm bore provides 628.3 N. The MI32X35SU hits a solid middle ground for medium-force tasks. Note that a standard pneumatic cylinder drifts when air pressure is lost or the valve is centred; the TPU bumpers only decelerate the end of stroke and will not lock the load. To suspend a vertical weight safely, install an external rod lock or a pilot-operated check valve. The short 35 mm stroke minimizes rod-bending side loads, and the 1/8 inch port ensures adequate flow for rapid cycling.
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 MI32X35SU FAQ
This 32 mm bore cylinder features a 1/8 inch port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches for position detection. It uses fixed TPU bumper pads to decelerate at stroke ends, but does not feature an adjustable air cushion.
