Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 260mm 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 MI25X260SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 260 mm linear movements. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises. Its riveted stainless barrel and Ø10 mm rod resist mild corrosion and washdown, offering a real edge over painted-steel alternatives in damp environments. A built-in magnet (-S) supports CMSG, DMSG and EMSG position switches.
Equipped with fixed TPU bumper pads to decelerate the stroke end, the unit operates at 30-800 mm/s. For real-world sizing, plan for roughly 147 N of usable work at 0.5 MPa, which translates to lifting about 12.5 kg vertically with a 2:1 safety margin. The 1/8" port and M10x1.25 male rod thread ensure robust pneumatic and mechanical connections for this CA clevis-mounted actuator.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SCA Is Used
Package Diverter Gate
Actuates a heavy routing flap on a packaging line, using the 245.3 N thrust to push assorted cartons cleanly into secondary lanes.
Pallet Stacking Arm
Drives a 260 mm lifting lever to position empty pallets, leveraging the CA clevis mount to accommodate the pivot arc.
Textile Loom Tensioner
Maintains consistent fabric tension in humid dye-house conditions, where the stainless steel rod prevents mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SCA the Right Cylinder?
When sizing this 245.3 N (0.5 MPa) unit, stepping down to a Ø20 bore yields 157.0 N, while stepping up to a Ø32 bore provides 402.2 N. This model includes a CA rear pivot cover for clevis mounting, ideal for angular load alignment. Because the standard MI lacks an adjustable air cushion, rely on the fixed TPU bumpers for end-of-stroke deceleration. The 260 mm stroke is within the 500 mm standard limit, though long strokes require careful alignment to prevent rod bending and side-load wear.
Note that a plain double-acting cylinder drifts when air is lost or the valve is centred; the bumpers only soften the impact, they do not act as a brake. To suspend a vertical load safely, integrate an external rod lock or a pilot-operated check valve into your circuit. The -S magnet enables electronic or reed sensor tracking along the body.
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 MI25X260SCA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
The CA designation means it has a rear pivot/clevis cover for articulated mounting. It cannot hold a load vertically on its own; air loss causes the piston to drift, as the fixed TPU bumper pads only decelerate the stroke end and do not function as a lock. Use a pilot check valve for load holding.
