About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-10
The AirTAC SAIJ100X500-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 7068N of push force at 0.9 MPa. It features a SUS304 stainless steel rod and PT tapered ports. The built-in rear stopper allows you to fine-tune the effective travel window down to 490-500 mm, providing exact end-position tuning without swapping out the entire unit.
Because this 500 mm stroke is relatively long, the M20x1.5 rod thread and 25 mm rod diameter provide robust support, though an external guide is still recommended to manage side loads. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-10 Is Used
Long-Stroke Press Tuning
Dial in the exact 490-500 mm end-of-stroke position on large pressing equipment without machining new hard stops.
Machine Changeover
Quickly adjust the retract position by up to 10 mm when switching between product variants on a shared line.
Heavy Material Handling
Move substantial loads with 7068N of push force at 0.9 MPa while trimming the travel window to suit varying material widths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-10 the Right Cylinder?
Choose this 100 mm bore cylinder when an 80 mm bore falls short (delivering 4523N push at 0.9 MPa) but you need precise 490-500 mm end-position control during commissioning. The 10 mm rear adjuster acts purely as a travel stop for deceleration and positioning, not a lock; the cylinder will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100 mm bore, 500 mm stroke, 10 mm adjustment range, PT port threads, and SUS304 rod material. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Operating speed ranges from 30-800 mm/s, and the long stroke necessitates external guiding to prevent rod deflection.

- ✓ 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 SAIJ100BX500-10 FAQ
The rear adjusting screw acts as an external stopper, allowing you to shorten the nominal 500 mm stroke by up to 10 mm. This creates a usable travel window of 490-500 mm for fine-tuning the retract end position during setup.
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068N of push force and 5497N of pull force. It reaches a maximum thrust of 801 kgf at 1.0 MPa.
