About the Airtac SAI125 Standard Air Cylinder SAI125AX260
The AirTAC SAI125X260 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It generates a push force of 6136 N at 0.5 MPa and 8590 N at 0.7 MPa, making it suitable for high-thrust pressing and heavy load manipulation. The 260 mm stroke provides substantial travel for substantial actuation tasks.
This model features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in harsh environments. The extruded aluminum barrel includes sensor grooves on both sides, allowing for flexible position monitoring. As a genuine AirTAC component, it ensures reliable performance across its 30-500 mm/s speed range.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX260 Is Used
Heavy-Duty Stamping
Provides the 8590 N force at 0.7 MPa required for metal forming, riveting, and heavy assembly press operations.
Automotive Component Handling
Actuates large jigs and fixtures with a 260 mm stroke, moving heavy chassis or powertrain parts reliably.
Pallet Positioning
Lifts or pushes loaded pallets in high-throughput logistics systems, utilizing the robust 125mm bore profile.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX260 the Right Cylinder?
When upgrading from a 100mm bore, the SAI125X260 significantly increases thrust from 5497 N to 8590 N at 0.7 MPa, accommodating larger payloads. If this force is excessive, stepping down to an 80mm bore reduces the push force to 3518 N. This model utilizes a PT tapered G1/2 port and pairs with standard ISO 15552 mounting accessories like the CA clevis or TC trunnion.
For applications requiring position holding without live air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke ends and do not function as a lock. In drop-prevention scenarios, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. Since the 260 mm stroke exceeds 300 mm is not applicable here, standard side-load management is sufficient, but always ensure linear guide rails for heavy loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
