About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X10SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles heavy-duty actuation within a remarkably compact 10 mm stroke. The riveted construction pairs a corrosion-resistant barrel and rod with fixed TPU bumper pads that absorb end-of-stroke impacts without requiring manual adjustment. Because this SKU includes the -S magnet, it is fully primed for CMSG, DMSG or EMSG position switches.
Operating at 0.15-1.0 MPa with a 1/8" port, the unit provides a practical safe working load of roughly 241 N. This translates to lifting a 20.5 kg part vertically with a 2:1 safety margin, allowing precise heavy part positioning. The U back cover orients the port 90 degrees to the body, simplifying hose routing in dense machinery layouts.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X10SU Is Used
Short-Stroke Clamping
Grips heavy metal castings in CNC fixturing, using the 402.2 N push force to hold parts securely against machining vibration.
Riveting Press
Drives a pneumatic rivet head over a 10 mm travel distance, relying on the fixed TPU bumpers to soften the sudden impact at the workpiece.
Pallet Stopper
Acts as a high-strength stop block on a conveyor line, throwing the 20.5 kg vertical lift capacity into halting heavy product flow instantly.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X10SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm version drops the 0.5 MPa push force to 245.3 N, whereas the larger 40 mm bore jumps to 628.3 N. This 32 mm model hits a strong middle ground for high-force, short-throw tasks. Note that a standard cylinder drifts when air is removed or a valve is centered; the TPU bumpers only decelerate the stroke end and will not lock the rod. For suspended loads, install an external rod lock or pilot check valve. The 12 mm rod and M10x1.25 male thread handle high side-loads, though even with a 10 mm stroke, maintaining true alignment prevents premature seal wear.
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 MI32X10SU FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 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 rod near the stroke end and do not act as a brake. You must use an external rod lock or pilot-operated check valve to hold a suspended load safely.
