About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-20S
The AirTAC SAIJ100X600-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa, utilizing a 25mm piston rod with an M20x1.5 thread. A standout feature is its 20mm adjustment range, which creates a precise 580-600mm usable travel window, allowing you to fine-tune the retract end position at commissioning without external stops.
This model includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and features a built-in magnet (-S) compatible with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-20S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 580-600mm window during machine setup to accommodate varying product lengths without swapping hardware.
Changeover Adjustment
Use the 20mm rear screw to quickly reposition the end-of-stroke stop when changing over production lines, eliminating the need for external mechanical spacers.
Heavy-Duty Positioning
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or fixtures, relying on the SUS304 rod for durability in demanding environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-20S the Right Cylinder?
Choose this 100mm bore cylinder when an 80mm bore (yielding 4523N at 0.9 MPa) cannot meet your thrust requirements, but a 125mm bore is oversized. The 20mm rear adjuster screw acts purely as a travel stop for end-position tuning during product changeovers; it does not hold the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI cylinder series.
To replace an ISO 15552 cylinder, match the 100mm bore, 600mm stroke, 20mm adjustment, PT G1/2 port, and -S magnet. Because the 600mm stroke is long and unsupported, you must use an external guide to prevent excessive side-loading on the M20x1.5 rod.
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 SAIJ100BX600-20S FAQ
At 0.9 MPa, this 100mm bore cylinder provides a push force of 7068N and a pull force of 3681N. It can deliver a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 600mm down to 580mm, creating a 580-600mm usable window. This stop only sets the end position; it does not lock or hold the load without continuous air pressure.
