About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-100
The AirTAC SAIJ100X500-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 500mm nominal stroke that can be dialed back by up to 100mm, creating a precise 400-500mm usable travel window for commissioning flexibility. Built with an SUS304 stainless steel rod and tapered PT ports, it delivers 3927N of push force at 0.5MPa.
This extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this specific SKU ships without a magnet. The rear screw acts purely as a travel stop to fine-tune end positions without adding external shims. For applications requiring position holding without live air pressure, consider the SAIL or BSAI locking cylinder series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-100 Is Used
Variable End-Stop Positioning
Dial in the 400-500mm travel window during machine commissioning to accommodate varying product lengths without physically remounting the actuator.
Automated Line Changeover
Quickly shorten the effective stroke by up to 100mm via the rear screw when switching production lines to different package dimensions.
Long-Stroke Assembly Presses
Leverage the 3927N push force at 0.5MPa across a 500mm span to drive heavy tooling, using the adjuster to set precise bottoming depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX500-100 the Right Cylinder?
Choose this 100mm bore cylinder when a 50mm bore (offering 982N push at 0.5MPa) lacks the thrust for heavy payloads, but an 80mm bore (2513N) is still undersized. The 100mm option yields 3927N at 0.5MPa, scaling up to 7068N at 0.9MPa. The 100mm adjustment range is ideal for machinery requiring significant product-size changeover flexibility, eliminating the need to physically swap cylinders when end-stops vary.
When replacing an ISO 15552 cylinder, match the 500mm stroke, 100mm bore, PT port thread, and SUS304 rod material. Because the stroke is 500mm, the 25mm rod diameter and M20x1.5 rod thread must be paired with an external guide to prevent side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on other series.
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 SAIJ100BX500-100 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. If pressure is increased to 0.9MPa, the push force reaches 7068N.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this model, the 500mm nominal stroke can be reduced to anywhere within a 400-500mm usable window. It does not lock the load; it only sets the travel end.
