Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCALB
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCALB is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 300mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCALB
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The riveted stainless barrel and Ø10 mm rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it carries the -S suffix, a built-in piston magnet is ready for CMSG, DMSG or EMSG position switches.
The 1/8" port feeds the 30-800 mm/s speed range, while fixed TPU bumper pads absorb the impact at stroke extremes. For practical sizing, plan for about 147 N of actual work at 0.5 MPa, which means it can comfortably lift a 12.5 kg part vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCALB Is Used
Package Divert Gate
Actuates a routing flap on a packaging line, using the 300 mm stroke to swing heavy cardboard cartons into a secondary sorting lane.
CNC Lathe Door
Slides a heavy machine-tool safety enclosure open and closed, relying on the stainless build to endure stray coolant spray.
Tote Stack Pusher
Pushes empty plastic totes into a stacking cradle, lifting or shifting loads up to 12.5 kg with a safe 2:1 vertical margin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300SCALB the Right Cylinder?
This 25 mm bore sits comfortably between the 16 mm option (140.7 N push at 0.7 MPa) and the larger 32 mm size (563.0 N push at 0.7 MPa), making it the sweet spot for medium-force clamping. The 300 mm stroke is well within the 500 mm maximum, though at this length you should ensure rigid guidance to prevent rod bending under side loads. The included LB foot bracket and CA pivot clevis cover your base and rear-pivot mounting needs.
Remember that the fixed TPU bumpers only soften the end-of-stroke impact; they do not act as a brake. If air pressure drops or the valve is centred, the piston will drift, so fit an external rod lock or pilot-operated check valve for applications requiring strict position holding.
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 MI25X300SCALB FAQ
This 25 mm bore cylinder features a 1/8" air port and an 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 Ø25 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. The -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG switches, and the unit includes fixed TPU bumper pads rather than an adjustable air cushion.
