About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-50
The AirTAC SAIJ100X600-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel anywhere within a 550 to 600 mm window. It delivers substantial thrust, pushing with 3927 N and pulling with 3681 N at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches later if position detection becomes necessary.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-50 Is Used
Variable End-Stop Machining
Dial in the 550-600 mm travel window during machine setup to accommodate different part lengths without repositioning the entire actuator assembly.
Product Changeover Diverters
Quickly adjust the retract position on a packaging line to handle varying box sizes, utilizing the 50 mm trim range to switch product profiles rapidly.
Heavy-Duty Press Setup
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets, fine-tuning the stopping point at commissioning to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-50 the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder lacks the required force, as the 80 mm only provides 2513 N of push force at 0.5 MPa compared to the 3927 N available here. The 50 mm rear adjuster is ideal for product changeovers, letting you dial in the exact end position without swapping the cylinder or adding external stopper blocks. Because the nominal stroke is 600 mm, the M20x1.5 rod and long travel distance mean an external guide rail is recommended to prevent excessive side-loading and premature seal wear.
Keep in mind the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. If your application requires true load-holding in the event of air loss, consider the SAIL pneumatic lock or BSAI clamp-lock cylinder series instead. For an exact ISO 15552 replacement, match the 100 mm bore, 600 mm stroke, 50 mm adjustment, PT port, and your preferred mounting style from the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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 SAIJ100BX600-50 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. If higher pressure is needed, it can output up to 5497 N push force at 0.7 MPa.
The rear adjuster screw allows you to shorten the 600 mm nominal stroke by up to 50 mm, providing an effective usable travel window of 550 to 600 mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
