About the Airtac SAI125 Standard Air Cylinder SAI125X10S
The AirTAC SAI125X10-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke, heavy-force tasks. It provides 6136 N of push force at 0.5 MPa, making it ideal for high-impact pressing and clamping. This specific variant includes a standard magnet for proximity sensing and features a durable carbon steel piston rod.
Because it is a profile barrel design without tie-rods, it offers a clean exterior and integrated mounting grooves. The included magnet allows direct mounting of CMSE or DMSE series reed switches along the barrel for precise end-of-stroke detection.

Where the Airtac SAI125 Standard Air Cylinder SAI125X10S Is Used
Short-Stroke Pressing
Generates 6136 N of force over a 10 mm travel to seat bearings and pins in automated assembly lines.
Heavy-Duty Clamping
Secures large metal castings or weldments during machining operations using immense holding power.
Ejector Mechanisms
Delivers rapid, high-energy ejection of finished parts from heavy-duty molds and fixtures.
Is the Airtac SAI125 Standard Air Cylinder SAI125X10S the Right Cylinder?
Choose this 125 mm bore when a system requires substantial thrust within a very compact footprint. If an application needs slightly less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 160 mm bore provides 10053 N for extreme load moving.
For this 10 mm stroke, side loading is minimal, but the high peak forces can stress mountings. Ensure rigid attachment using ISO 15552 compatible flanges. Note that the adjustable air cushions at both ends decelerate the piston, but this model will not hold a load if air pressure is lost; use an external pilot-operated check valve for position holding.
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.
