About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350SCATC
Generating 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 350 mm linear movements. The Ø25 mm bore uses a 1/8 inch port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, making it highly suitable for damp or washdown environments where painted carbon steel units degrade. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb end-of-stroke impacts.
Because the 245.3 N rating is a theoretical maximum, plan for a safe working load of roughly 147 N to account for friction and pressure drops. In vertical lifting setups, this translates to hoisting about 12.5 kg safely with a 2:1 margin. The built-in -S piston magnet allows seamless integration with CMSG, DMSG, or EMSG switches for position sensing. Conforming to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350SCATC Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 245.3 N force to push heavy cartons onto secondary tracks at high cycling speeds.
Vertical Parts Lift
Raises lightweight industrial totes 350 mm between conveyor tiers, safely lifting loads up to 12.5 kg in automated storage retrieval systems.
Washdown Valve Actuation
Drives a diverter valve in a food-grade washdown zone, leveraging the stainless steel construction to withstand moisture and cleaning chemicals.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X350SCATC the Right Cylinder?
When sizing this unit, the smaller Ø20 bore offers 157.0 N of push at 0.5 MPa, whereas stepping up to the larger Ø32 bore yields 402.2 N. This model includes a CA rear pivot cover and a TC trunnion mount, providing a pivoting anchor point that accommodates misalignment on longer 350 mm strokes. Be mindful that extended strokes increase rod bending moments, so minimizing side loading is critical to prevent premature seal wear.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The TPU bumpers only decelerate the piston near the stroke ends and do not function as a locking mechanism. To suspend a load safely during an air failure, install an external rod lock or a pilot-operated check valve.
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 MI25X350SCATC FAQ
At 0.5 MPa, the push force is 245.3 N and the pull force is 206.1 N. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. This Ø25 mm bore cylinder features a 1/8 inch air port and a piston rod with an M10x1.25 male thread.
No, the fixed TPU bumper pads only decelerate the piston at stroke end and do not lock the load; you need an external rod lock or pilot check valve to hold position vertically. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG reed or electronic switches for precise end-position detection.
