About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-30S
The AirTAC SAIJ100X600-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 600 mm stroke that can be dialed back by up to 30 mm, giving you a precise 570-600 mm usable travel window for exact end-position tuning during commissioning. Delivering a robust 5497 N push force at 0.7 MPa, it handles heavy dynamic loads with ease.
This variant includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered ports (G1/2). The extruded aluminum barrel integrates sensor grooves on both sides, and the -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to decelerate the end-of-stroke, not as a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-30S Is Used
Variable End-Stop Positioning
Dial in the 570-600 mm travel window during machine commissioning to perfectly strike a press or clamp without re-machining hard stops.
Product Size Changeover
Quickly adapt the retract distance on a packaging line when product dimensions change, using the 30 mm rear adjustment screw to trim the stroke.
Heavy-Duty Forming
Leverage the 5497 N push force at 0.7 MPa for robust forming operations while fine-tuning the exact bottom-dead-center position on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-30S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when your machine setup requires variable end-stops or frequent product-size changeovers without physically swapping the cylinder or adding external stops. If you need to step down force, the 80 mm bore provides 3518 N push at 0.7 MPa; stepping up to the 125 mm bore yields 8590 N. To match this exact ISO 15552 replacement, specify a 100 mm bore, 600 mm stroke, 30 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
Because the stroke is 600 mm, the 25 mm diameter rod is highly susceptible to side-loading and sagging; an external guide rail is strongly recommended to prevent premature seal wear. Furthermore, a plain SAIJ does not hold its load without live air pressure. For true load-holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead of relying on the adjustment screw.
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 SAIJ100BX600-30S FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. The maximum push force at 1.0 MPa is 801 kgf.
The rear adjuster screw lets you shorten the effective travel from 600 mm down to 570 mm, creating a 570-600 mm window. It functions as a mechanical stop to fine-tune the end position, but it does not lock or hold the load without continuous air pressure.
