About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 500 mm strokes with ease. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of adjustable cushions.
For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which safely lifts about 12.5 kg vertically with a 2:1 margin. The rear CA pivot clevis accommodates angular movement. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500CA Is Used
Packaging Line Diverter
Pushes cartons across a 500 mm gap on a washdown packaging line, utilizing the stainless steel construction to resist moisture and cleaning chemicals.
Textile Loom Tensioner
Extends a full half-meter to position tensioning guides, relying on the 245.3 N push force at 0.5 MPa to maintain fabric tracking.
Palletizer Gate Actuator
Operates a heavy swing gate via the rear CA clevis, using the 206.1 N pull force at 0.5 MPa to retract the barrier for forklift access.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500CA the Right Cylinder?
When sizing this 500 mm stroke model, verify your actual load against the 245.3 N push rating at 0.5 MPa. If you need less force, the Ø20 bore provides 157.0 N push, while stepping up to the Ø32 bore yields 402.2 N. This unit features the CA rear pivot cover, so pair it with a matching clevis bracket. At a full 500 mm extension, minimize side-loading to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed TPU pads only soften the end-of-stroke impact rather than locking the piston. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock.
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 MI25X500CA FAQ
This Ø25 mm bore cylinder features a 1/8" port and an M10x1.25 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.
Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG or EMSG magnetic switches. Mechanically, it uses the ISO 6432 mounting interface for Ø8-Ø25 bores, so it drops directly into standard mini-cylinder brackets and clevises. It uses fixed TPU bumper pads, not an adjustable air cushion.
