About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30
The AirTAC SAIJ100X500-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 500 mm stroke that can be dialed back by up to 30 mm, yielding a precise 470-500 mm usable travel window for fine-tuning end positions during commissioning. Delivering 5497 N of push force at 0.7 MPa, it handles heavy loads with a robust 25 mm piston rod.
This variant is configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the rear adjuster acts strictly as a mechanical stop and does not hold the load without live air, you must maintain continuous pneumatic pressure during operation.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30 Is Used
Product Changeover
Dial in the 470-500 mm travel window during format size changes on a packaging line without physically swapping out the entire actuator.
Machine Setup
Fine-tune the retract end-position at commissioning to achieve exact positioning, absorbing mechanical tolerances in the fixture build.
Heavy Material Handling
Leverage the 5497 N push force to move heavy pallets or workpieces, using the adjustable stop to tweak the resting distance safely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-30 the Right Cylinder?
Choose this 100 mm bore cylinder when an 80 mm bore falls short on power, as the 80 mm delivers only 3518 N of push force at 0.7 MPa compared to the 5497 N provided here. The 30 mm adjustment range is ideal for product-size changeovers on a line, allowing you to shift the end-stop without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on the adjuster.
To replace an ISO 15552 cylinder, match the 100 mm bore, 500 mm stroke, 30 mm adjustment, PT G1/2 port, and your required mounting style. Available mounts include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since this features a 500 mm stroke, the extended travel increases the risk of side-loading; ensure you use an external guide to support the load and protect the rod seals.
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 SAIJ100BX500-30 FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. It can reach a maximum push force of 7068 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 500 mm down to 470 mm. It sets the travel end but does not lock or hold the load without continuous live air pressure.
