About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-10S
The AirTAC SAIJ100X280-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 270 to 280 mm. Delivering 3927 N of push force at 0.5 MPa, this unit handles substantial loads while allowing precise end-position tuning during commissioning without swapping out the entire actuator.
This variant features a carbon steel rod and a built-in magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves. The rear adjuster acts strictly as a mechanical stop for position refinement and relies on the integrated air cushions for end-of-stroke deceleration; it does not lock or hold the load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-10S Is Used
Product Changeovers
Dial in the 10 mm adjustment window to quickly adapt the 270-280 mm travel end-position for varying part sizes on a machining line.
Commissioning Calibration
Fine-tune the final retract position during machine setup without fabricating external stopper blocks or replacing the actuator.
Heavy Material Handling
Leverage the 3927 N push force to move heavy pallets or workpieces while gently decelerating loads using the adjustable air cushions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-10S the Right Cylinder?
Selecting this 100 mm bore actuator makes sense when your application requires the 3927 N push force at 0.5 MPa and on-the-fly end-stop trimming within a 10 mm range. If your setup demands less force, stepping down to an 80 mm bore yields 2513 N of push force, whereas moving up to a 125 mm bore provides 6136 N. Because the stroke is 280 mm, supporting the load with an external guide is recommended to prevent excessive side-loading on the 25 mm carbon steel rod and its M20x1.5 thread.
An adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers rather than machining custom external stops. To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 280 mm stroke, 10 mm adjuster, PT tapered port threads, and your preferred mounting from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. For load-holding without live pressure, consider the SAIL or BSAI series instead.
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.
Airtac SAIJ100 Adjustable Cylinder SAIJ100X280-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster acts as a mechanical stop that shortens the nominal 280 mm stroke by up to 10 mm, creating a 270-280 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
