About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X410SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 410 mm strokes with ease. The Ø25 bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration. Its riveted stainless barrel and rod resist mild corrosion, offering a distinct advantage over painted alternatives in damp or washdown environments.
Equipped with a built-in piston magnet (-S), the unit supports CMSG, DMSG, and EMSG reed or electronic switches for precise end-position detection. The fixed TPU bumper pads absorb stroke-end impact without the complexity of adjustable cushioning. For practical sizing, plan for a safe working load of roughly 147 N, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X410SU Is Used
Diverting Gate Actuation
Pushes heavy cardboard cartons on a packaging line, utilizing the 245.3 N push force to pivot heavy routing gates reliably over the 410 mm travel.
Vertical Parts Ejection
Lifts finished molded components weighing up to 12.5 kg out of a press bed, relying on the stainless build to resist factory humidity and coolant mist.
Textile Beam Indexing
Extends 410 mm to shift large textile beams between processing stations, using the U-type back cover for a secure 90-degree pivot mount.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X410SU the Right Cylinder?
When sizing this 245.3 N (at 0.5 MPa) unit, consider the neighbouring bores: a Ø20 provides 157.0 N, while a Ø32 steps up significantly to 402.2 N. This model includes a U-type 90-degree rear cover for versatile pivot mounting alongside standard LB foot, FA flange, and TC trunnion options. Because the 410 mm stroke approaches the 500 mm maximum for this bore, ensure adequate guidance to prevent rod bending under side loads.
Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered—the TPU bumpers only decelerate the stroke end and do not function as a lock. To suspend a load safely during an emergency stop, integrate an external rod lock or a pilot-operated check valve into your 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 MI25X410SU FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245.3 N of push force and 206.1 N of pull force. At 0.7 MPa, push increases to 343.4 N and pull to 288.5 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The air port is 1/8" (PT standard, G optional), and the male rod thread is M10x1.25.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the cylinder body. This specific SKU features a U-type 90-degree back cover, which provides a pivot pin mounting configuration ideal for articulating mechanisms.
