About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-10
The AirTAC SAIJ100X500-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 500 mm travel but features a 10 mm external stopper screw, creating a 490-500 mm usable window for fine-tuning the retract end position during commissioning. Delivering a robust 7068 N of push force at 0.9 MPa, it handles heavy loads while maintaining a standard 30-800 mm/s speed range.
This model utilizes a carbon steel piston rod with an M20x1.5 thread, paired with a G1/2 port for optimal air flow. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-10 Is Used
Machine Setup Changeover
Dial in the exact 490-500 mm retract position during product family changeovers without physically swapping the actuator or shimming external stops.
Heavy Material Forming
Leverage the 7068 N push force at 0.9 MPa to form or press heavy components, using the rear stopper to fine-tune the final bottoming position.
Long-Stroke Alignment
Execute 500 mm travel movements in large assembly jigs, relying on the 10 mm adjustment window to perfectly square the end position against the workpiece.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X500-10 the Right Cylinder?
Select this 100 mm bore actuator when an application requires high thrust—such as 3927 N push at 0.5 MPa—that smaller 80 mm bores (2513 N) cannot provide, without stepping up to the massive 125 mm class. The adjustable stroke is ideal for product changeovers, allowing you to dial in the exact end-stop mechanically rather than swapping cylinders or adding external stops. Because the 500 mm stroke is relatively long, ensure adequate external guidance to prevent excessive side-loading on the M20x1.5 rod.
When specifying a replacement, verify the 100 mm bore, 500 mm stroke, 10 mm adjustment range, PT tapered port thread, and the required mounting bracket. Remember that the rear adjuster is a travel stop, not a locking device; this cylinder will not hold a load without live air pressure. For true load-holding, 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 SAIJ100X500-10 FAQ
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 801 kgf.
A rear stopper screw lets you shorten the effective travel by up to 10 mm, providing a 490-500 mm usable window. It acts as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
