About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for easy design integration. Its riveted stainless barrel and piston rod resist mild corrosion, outperforming painted alternatives in damp environments.
Fitted with a CA rear pivot cover, the 300 mm stroke is driven by a Ø10 mm rod with an M10×1.25 male thread. Fixed TPU bumper pads absorb end-of-stroke impact. Plan for roughly 147 N of actual work at 0.5 MPa, which means it can vertically lift about 12.5 kg with a safe 2:1 margin. Air connects via a 1/8" port.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300CA Is Used
Package Diverter Arm
Uses the CA pivot mount to swing a 300 mm arm, routing 12 kg cartons on a packaging line with reliable 245.3 N push force.
Textile Loom Tensioner
Stainless construction withstands humid textile facilities while maintaining consistent yarn tension across the long 300 mm travel.
Pallet Gate Actuator
Drives a sliding safety gate on a palletizer, where the ISO 6432 dimensions allow direct replacement into existing clevis brackets.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X300CA the Right Cylinder?
When sizing this 245.3 N (at 0.5 MPa) unit, the smaller Ø20 bore provides 157.0 N, while the larger non-ISO Ø32 bore offers 402.2 N if more force is required. The 300 mm stroke is well within the 500 mm maximum, but at extended lengths you must minimize side-loading to prevent rod bending. The CA back cover provides a rear pivot point ideal for articulating mechanisms.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; add an -S variant if sensing is required. Remember that venting the air causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. Use a pilot-operated check valve or external rod lock to hold a suspended weight.
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 MI25X300CA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8".
No, this specific SKU does not have a magnet. You must choose an MI25 model with the -S suffix to use CMSG, DMSG or EMSG switches. It features fixed TPU bumper pads, not an adjustable air cushion.
