About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial workloads in compact spaces. The riveted barrel and rod shrug off mild corrosion, making it far superior to painted alternatives in damp or washdown environments. Equipped with a 1/8" port and a 10 mm rod, it operates efficiently between 30-800 mm/s.
It features fixed TPU bumper pads that absorb stroke-end impacts without the complexity of adjustable cushioning. For real-world sizing, plan for a safe working load of roughly 147 N, which means it can comfortably lift about 12.5 kg vertically with a 2:1 safety margin. The built-in magnet supports CMSG, DMSG, and EMSG sensors for position tracking.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCA Is Used
Package Diverter Gate
Swings a heavy routing flap on a packaging line using its CA pivot clevis, relying on the 245.3 N push force to overcome friction from accumulated cardboard cartons.
Press Pin Insertion
Drives a 10 mm rod downward to seat metal dowels into an aluminum housing, utilizing the 12.5 kg vertical lift capacity to press parts securely into place.
Pallet Stop Arm
Extends an 80 mm stroke to deploy a physical stop block on a roller conveyor, halting loaded pallets with confidence in mildly humid storage environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X80SCA the Right Cylinder?
When sizing this 80 mm stroke unit, the Ø20 bore provides a smaller alternative with 157 N of push at 0.5 MPa, while stepping up to the Ø32 bore yields 402 N if your application demands more power. Because the CA back cover provides a rear pivot, ensure your mounting geometry accommodates the clevis swing. Keep in mind that a standard cylinder drifts if air pressure is lost or the valve is centered; the bumpers only decelerate the stroke end and will not lock the load, so add an external rod lock or pilot check valve if position holding is critical. The ISO 6432 mounting interface on this Ø25 bore ensures it drops directly into standard mini-cylinder brackets and clevises.
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 MI25X80SCA FAQ
This Ø25 mm bore cylinder features a 1/8" port and a M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG reed or electronic switches along the body. The CA back cover provides an integrated clevis pin for pivot mounting, which pairs well with the ISO 6432 standard dimensions of this Ø25 bore for versatile installation.
