About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-50S
The AirTAC SAIJ100X600-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 550-600mm. Delivering 3927N of push force at 0.5MPa, it features a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet for CMSE and DMSE sensors.
This 100mm bore unit utilizes PT tapered port threads and includes variable air cushions at both ends to absorb kinetic energy. The rear mechanical stopper allows precise end-position tuning during commissioning without adding external stops, though it acts purely as a travel limiter and not a lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-50S Is Used
Variable End-Stop Machining
Dial in the 550-600mm travel window to accommodate multiple part lengths on a single fixture without physically swapping out the entire cylinder assembly.
Machine Setup Commissioning
Fine-tune the retract end-position during initial machine build or product changeover using the rear adjustment screw, avoiding the need for external shims.
Product Sorting Diverter
Adjust the diverter stroke by up to 50mm on the fly to handle varying package sizes on a conveyor line while maintaining 3927N of pushing force.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-50S the Right Cylinder?
Selecting this 100mm bore makes sense when an 80mm bore (2513N push at 0.5MPa) lacks the necessary thrust, but stepping up to a 125mm unit (6136N) would be physically oversized. The 50mm adjustment range is ideal for product changeovers, letting operators dial in the exact end-position on the fly. For load-holding without live air pressure, this cylinder will not suffice, as the adjuster is only a stop; you must look toward SAIL or BSAI series cylinders instead.
Because the 600mm stroke is substantial, the 25mm rod diameter should be paired with an external guide to prevent excessive side-loading and premature seal wear. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ100BX600-50S FAQ
At a 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can reach up to 7068N push force at 0.9MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 600mm nominal stroke by up to 50mm, creating a 550-600mm usable travel window. It sets the end-position but does not lock the load without live air.
